    Study Notes

    Urination & Thirst

    • Prolonged undetected/untreated diabetes can lead to neurological or cardiovascular abnormalities.
    • Chronic skin and yeast infections indicate immune system dysfunction.
    • Increased centripetal fat distribution is a sign of diabetes, with waist circumference greater than 40 inches for men and 35 inches for women.
    • Acanthosis nigricans, a darkening of the skin in skin folds with associated skin tags, indicates significant insulin resistance.
    • Eruptive xanthomas are a consequence of hyperchylomicronemia, characterized by increased triglycerides.

    Diabetes Screening

    • Many people with Type 2 Diabetes are asymptomatic and unaware of their condition.
    • Early intervention in Type 2 Diabetes leads to superior outcomes.
    • Screening for Type 2 Diabetes is essential to prevent complications and progression.
    • People with prediabetes should increase efforts towards diabetes prevention.
    • Screening is cost-effective.

    Type 2 Diabetes (T2DM) Screening Guidelines

    • Overweight or obese individuals with one or more risk factors should be screened.
      • Family history of diabetes, ethnicity (African American, Latino, Asian, etc.), hypertension, low HDL or high triglycerides, PCOS, acanthosis nigricans, history of heart disease, physical inactivity, insulin resistance (e.g., severe obesity)
    • Individuals previously diagnosed with high blood sugar (IFG, IGT, A1C 5.7-6.4%) should be screened annually.
    • Women with a history of gestational diabetes should be screened every three years.
    • Everyone should begin screening at age 45, every three years.
    • People with HIV should be screened regularly.

    T2DM Diagnostic Evaluation

    • Glucose tolerance can be classified into three categories: normal glucose homeostasis, impaired glucose homeostasis, and diabetes mellitus.
    • Diagnosis of T2DM in non-pregnant patients is based on any of four abnormalities:
      • Elevated fasting plasma glucose (FPG)
      • Random elevated glucose with symptoms
      • Elevated HgB A1C
      • Abnormal oral glucose tolerance test (OGTT)
    • Plasma/serum glucose is a more accurate measure of glucose concentration than blood glucose because it avoids interference from red blood cell concentration (Hct).

    Monogenic Diabetes (MODY)

    • Single gene disorders resulting in genetic defects of pancreatic beta cell function.
    • Genes involved control pancreatic beta cell development, function, and regulation. Mutations in these genes cause impaired glucose sensing and insulin secretion with minimal or no defect in insulin.
    • Non-insulin requiring diabetes (typically), although some forms of MODY may require insulin.
    • Most common form of monogenic diabetes, accounting for 2-5% of diabetes cases.
    • Age of onset is typically ≤25 years old, with a lack of autoantibodies (differentiating MODY from Type 1 Diabetes).
    • Autosomal dominant inheritance, with multiple gene abnormalities on different chromosomes.
    • Most common causes are GCK (glucokinase) and HNF (hepatocyte nuclear factor) mutations.
      • GCK Mutation:
        • Causes mild asymptomatic stable fasting hyperglycemia.
        • Glucose sensor molecules are defective, requiring higher plasma glucose levels to stimulate insulin secretion.
        • Resulting hyperglycemia is often stable and mild, not associated with the vascular complications common in other types of diabetes.
        • No treatment required.
      • HNF Mutation:
        • Causes progressive pancreatic beta cell dysfunction and hyperglycemia, which can lead to microvascular complications.
        • Can be well controlled with a sulfonylurea.
        • Hepatocyte Nuclear Factor 4-alpha (MODY1): Patients are at risk for hyperglycemia-associated microvascular and macrovascular complications of diabetes.
        • Hepatocyte Nuclear Factor-1 (MODY3): Most common form, especially among Europeans.

    Obesity

    • Obesity is a major public health concern, characterized by excessive body fat accumulation.
    • Obesity is associated with a range of health complications, including hypertension, hyperlipidemia, type 2 diabetes, osteoarthritis, psychosocial disability, increased cancer risk, thromboembolic disorders, digestive tract diseases, and skin disorders.

    Obesity Treatment Options

    • Lifestyle Modification:
      • Dietary Changes:
        • Calorie restriction, focus on fruits vegetables, whole grains, lean protein.

          • MOA: Amphetamine + anticonvulsant.
          • Side Effects: Addictive potential, hypertension, tachycardia.
          • Distribution in the US is restricted (Class IV drug).
        • Naltrexone + Bupropion:
          • 2-4% weight loss.
          • MOA: Opioid antagonist + NE-dopamine reuptake inhibitor.
          • Side Effects: Possible suicide, seizures, hypertension, tachycardia.
        • Liraglutide (Saxenda, Victoza):

          • Concerns: Thyroid tumors, pancreatitis, gallbladder disease, renal impairment, tachycardia, suicidal thoughts.
          • Side Effects: Nausea, vomiting, diarrhea, constipation, hypoglycemia.
    • Bariatric Surgery:
      • Considered for patients with:
        • Severe obesity (BMI ≥ 40)
        • Moderate obesity (BMI ≥ 35) associated with serious medical conditions/co-morbidities.
        • Obesity co-morbidities: joint disease, obstructive sleep apnea (OSA), diabetes, hypertension, GERD.
      • Surgical procedures include:
        • Roux-en-Y gastric bypass
        • Gastric banding
        • Sleeve gastrectomy
        • Intraluminal gastric balloon
          • Intraluminal gastric balloon devices are placed in the stomach endoscopically.
          • Two devices approved: RESHAPE (consists of two silicone balloons connected to a central silicone shaft) and ORBERA (single-balloon device).
          • Mean weight loss of 7.2 kg and 8.8 kg, respectively, was seen in short-term pivotal trials.
          • Both systems are approved only for ≤ 6 months of use in adults with a BMI of 30-40.
          • Adverse Effects: Nausea, vomiting, abdominal pain.
      • Complications: infection, hernia, nutritional deficiencies, neuropathy, blood clots.
      • Mortality: 1% risk postoperatively, with higher rates within the first year after surgery.
      • Multidisciplinary approach: diet, exercise, behavior modification, social support, pre-meal planning.

    Hirsutism

    • Excessive hair growth in women, often in male-pattern distribution, can be a symptom of various endocrine disorders.
    • Hirsutism can range from mild to severe, with varying symptoms and underlying causes.
    • Possible causes of Hirsutism include:
      • Polycystic Ovarian Syndrome (PCOS): The most common endocrine disorder in reproductive-age women, accounting for 90% of hyperandrogenism.
      • Ovarian Hyperthecosis: A nonmalignant ovarian disorder with increased testosterone production from luteinized thecal cells.
      • Androgen-secreting tumors: usually occur later in life and progress rapidly compared to PCOS, accounting for approximately 5% of ovarian tumors.
      • Uncommon causes:
        • Hyperprolactinemia (pituitary adenoma)
        • Acromegaly (pituitary adenoma)
        • Hypothyroidism
        • Severe insulin resistance
        • Drugs: Androgenic medications (e.g., testosterone, DHEA), Danazol

    Hirsutism Clinical Presentation

    • Mild to moderate hirsutism: Regular menses, no clear cause. Consider idiopathic hirsutism.
    • Hirsutism with acne, male pattern hair loss, acanthosis nigricans, obesity, and/or oligomenorrhea.
    • Increased prolactin (PRL): Galactorrhea (milk production), vision changes, infertility, oligo/amenorrhea (irregular or absent menstrual cycles).
    • Congenital Adrenal Hyperplasia (CAH): Menstrual abnormalities, virilization (development of male characteristics in females), increased DHEA/DHEA-S/androstenedione.
    • Androgen-secreting tumor: Older age, rapid progression, virilization.
    • Ovarian hyperthecosis: Older age, intense slow-progressing hirsutism.

    Hirsutism Diagnostic Evaluation

    • Idiopathic Hirsutism:
      • Total testosterone: Normal
    • Polycystic Ovarian Syndrome (PCOS):
      • Total testosterone: Usually elevated.
      • Transvaginal Ultrasound (TVUS): Necessary for evaluation.
    • Androgen-secreting Tumor:
      • Total testosterone: Elevated ≥2x normal values.
      • DHEAS (primarily adrenal origin) and androstenedione (primarily ovarian origin): Required for assessment.
      • Pelvic ultrasound: Recommended.
      • CT of the abdomen and pelvis.
    • Ovarian Hyperthecosis:
      • Total testosterone: Elevated.
      • TVUS.
    • DHEAS:
      • Elevated DHEAS suggests adrenal carcinoma.

    Hirsutism Treatment

    • Treat underlying causes:
      • Remove tumor.
      • Block androgen production: Oral contraceptive pills suppress GnRH, LH, and FSH, reducing ovarian androgens.
    • Block androgen response:
      • Spironolactone (androgen antagonist): Recommended.
      • Finasteride: Inhibits 5-alpha-reductase type 2, an enzyme that converts testosterone to dihydrotestosterone (DHT). Concerns exist regarding inadvertent use during pregnancy.
      • Flutamide: Non-steroidal androgen receptor antagonist, primarily used for prostate cancer but sometimes used off-label.
      • Antiandrogens are contraindicated during pregnancy.
    • Block hair growth: Vaniqa (eflornithine) cream retards hair growth.
    • Hair removal:
      • Depilatory creams (e.g., Nair)
      • Electrolysis, laser ablation
      • Manual removal (plucking)

    Hirsutism Urgent Considerations

    • Rapid virilization: Evaluate for a tumor.
      • Adrenal gland CT.
      • Ovarian transvaginal ultrasound.

    Polycystic Ovarian Syndrome (PCOS)

    • The most common endocrine disorder in reproductive-age women, affecting 5- 10%.
    • Accounts for 90% of hyperandrogenism in women.
    • Prevalence does not vary across different regions of the world.
    • Causes menstrual irregularity and androgen excess.
    • Symptoms: Hirsutism, irregular menses, polycystic ovarian morphology on transvaginal ultrasound.

    PCOS Etiology

    • Unknown etiology: Multiple systems involved; the primary defect is unclear.
    • Theories:
      • Hypothalamic-pituitary axis defect → Increased amplitude and frequency of LH pulses → Increased gonadal androgens.
      • Intrinsic ovarian defect → Androgen overproduction and anovulation (lack of ovulation).
      • Defects in insulin sensitivity = Insulin resistance → Hyperinsulinemia.
    • Pathophysiology: Not well understood; multiple mechanisms are possible.

    PCOS Risk Factors

    • Family history: PCOS is inherited as a common complex disorder with multiple genes involved.
    • Premature adrenarche: Before age 8 in girls.

    PCOS Signs/Symptoms

    • Menstrual Dysfunction: Delayed menarche, oligomenorrhea (irregular flow), amenorrhea (no menses for 3+ months).
    • Hyperandrogenism: Hirsutism, acne, male pattern hair loss; most women with PCOS have elevated androgens.
    • Hirsutism
    • Polycystic Ovaries: Seen on TVUS.
    • Metabolic/Cardiovascular Risks:
      • 40-85% of patients with PCOS are overweight or obese.
      • Insulin resistance, Type 2 diabetes, coronary artery disease (CAD), sleep apnea, nonalcoholic fatty liver disease.
    • Mood: Linked to depression, anxiety, impaired quality of life, and eating disorders.
    • Additional Symptoms: Hirsutism (60%), Acne (20%), Scalp hair loss (5%), Oligomenorrhea (< 6-8 menses per year), Amenorrhea (no menses), Irregular menses, weight gain, infertility.
    • Physical Examination Findings: Hirsutism, acne, alopecia (hair loss), possible hypertension, acanthosis nigricans, sweating, oily skin.

    PCOS Differential Diagnosis

    • Congenital Adrenal Hyperplasia (CAH) = 21-hydroxylase deficiency: Most common cause of CAH, resulting in a missing enzyme that leads to overproduction of adrenal hormones.
    • Thyroid Dysfunction
    • Hyperprolactinemia
    • Cushing Syndrome (rare)
    • Androgen-secreting neoplasm

    PCOS Diagnostic Evaluation

    • Rotterdam Criteria (Preferred): Two out of three required.

      • Oligo- and/or anovulation
      • Clinical and/or biochemical signs of hyperandrogenism
      • Polycystic ovaries (by ultrasound)

    • Diagnosis is confirmed after excluding other conditions: thyroid disease, nonclassic congenital adrenal hyperplasia (NCCAH), hyperprolactinemia, androgen-secreting tumors.

    • Serum total testosterone:

      • Measure if evidence of androgen excess.
      • Upper limit of normal for women is 45-60.
      • Levels > 150 require evaluation for an ovarian or adrenal androgen-secreting tumor or ovarian hyperthecosis.

    • DHEAS:

      • Not suggested for every patient.
      • Measure for symptoms of severe hyperandrogenism.
      • Can be extremely elevated in patients with adrenal carcinoma.

    • Androstenedione: Its role in the evaluation of PCOS is unclear; mixed results have been reported.

    • Serum 17-hydroxyprogesterone:

      • Morning level in the early follicular phase is measured to rule out congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

      • 800 indicates adrenal hyperplasia.

    • FSH and estradiol: High in premature ovarian insufficiency (also have low estradiol).

    • TSH: Check for thyroid abnormalities (can also cause irregular menses/ovulation).

    • Increased prolactin: Pituitary adenoma causes irregular menses, ovulation, and galactorrhea.

    • Cushing syndrome: If suspected, perform a 24-hour urine cortisol or dexamethasone test. Shared symptoms include: oligomenorrhea, hirsutism, obesity, hypertension, striae (stretch marks), muscle weakness.

    • Transvaginal Ultrasound (TVUS): Used to check for polycystic ovarian morphology (PCOM).

      • Not all suspected PCOS patients need an ultrasound.
      • If oligomenorrhea and hyperandrogenism are present, PCOS can be diagnosed without an ultrasound.
      • TVUS is used in hyperandrogenic women with normal menstrual cycles to check for PCOM.

    • Pelvic ultrasound:

      • ≥ 12 follicles in either ovary measuring 2-9 mm in diameter OR Ovarian volume > 10 cm3

    • Basal body temperature chart:

      • Absence of a biphasic pattern indicates anovulation.
      • Rarely used now.

    • Other considerations:

      • Blood pressure (BP), BMI, waist circumference (CVD risk)
      • Fasting lipid profile
      • 2-hour OGTT (oral glucose tolerance test) or fasting glucose and hgbA1C (hemoglobin A1C)
      • Screen for OSA (obstructive sleep apnea)
      • Liver enzymes (US is not recommended for screening for fatty liver)
      • Screen for depression and anxiety disorders.

      PCOS Treatment

    • Obese patients: Weight loss and exercise can reverse metabolic issues and induce ovulation.

    • Non-pregnancy patients:

    • First-line: Combined hormonal oral contraceptive pills (OCPs) for hyperandrogenism and menstrual irregularities.

    • Alternatives: Intermittent or continuous progestin therapy or hormonal intrauterine device (IUD) for endometrial protection.

    • Metformin: Second-line, improves menstrual function but has no effect on hirsutism, acne, or infertility: Used for glucose issues.

    • Medroxyprogesterone (Provera) (10 mg q.d. PO for the first 10 days of each month): Only initiates and regulates menses but does not inhibit androgen excess.

    • Low-dose combination OCPs: - Use low-androgenic activity progestins. - Regulates menses and may decrease androgens while preventing pregnancy.

    • Patients who desire pregnancy:

      • Ovulation stimulation:
        • Letrozole (first-line)
        • Clomiphene
        • Increased risk of twins with ovarian stimulation.

    • Hirsutism:

      • Low-dose combination OCPs for 6-12 months
      • If not improved, add spironolactone 25 mg PO tid (only use with contraception).
      • Topical eflornithine (Vaniqa) cream applied to the face BID for 6 months.
      • Electrolysis/laser therapy as needed (PRN).

    PCOS Prognosis

    • Insulin resistance and hyperinsulinemia increase the risk of Type 2 diabetes.
    • Anovulation causes unopposed estrogen, which increases the risk of endometrial cancer.
    • Pregnancy desired: 20-40% live birth rate with clomiphene treatment.

    Type II Diabetes Mellitus

    • Type 2 Diabetes Mellitus (T2DM) is characterized by progressive loss of beta cell insulin secretion with varying degrees of tissue insensitivity to insulin.
    • T2DM is the most common type of diabetes, accounting for over 90-95% of all diabetes cases in the US.
    • T2DM is a very expensive disease, costing $327 billion per year in 2017.
    • T2DM is associated with increased risk of microvascular complications (retinopathy, neuropathy, nephropathy) and macrovascular complications (coronary artery disease, peripheral arterial disease, stroke).

    T2DM Pathophysiology

    • Insulin facilitates the movement of glucose from blood into cells for energy use, transporting glucose to the liver and muscles for energy utilization and storing glucose in fat tissue.
    • T2DM patients produce insulin, but often not enough for the body’s needs, and may struggle to use produced insulin effectively.
    • Insulin levels are sufficient to prevent ketoacidosis but not hyperglycemia.

    T2DM Etiology

    • T2DM is caused by a combination of genetic and environmental factors.
    • Genetics play a significant role, with a high heritability (30-70%) and over 60 genetic variants.
    • Environmental factors play a significant role, with obesity being the highest absolute risk factor.
    • Other environmental factors include reduced activity, age, poor diet, and prior gestational diabetes.

    T2DM Epidemiology

    • The highest prevalence of T2DM in the US is among American-Indian and Alaskan populations.
    • The highest prevalence of T2DM globally is in China.
    • T2DM has a higher prevalence in certain Pacific islands and the Middle East, and an intermediate prevalence in countries like India and the US.
    • T2DM has peak incidence in minority groups over 45 years of age (slightly younger than white onset).
    • Males are slightly more likely to have T2DM than females.

    T2DM Clinical Presentation

    • T2DM is often asymptomatic, with an insidious onset.
    • Patients are often overweight or obese.
    • Patients may experience increased thirst, frequent urination, increased hunger, weight loss, blurred vision, fatigue, slow-healing sores, and frequent infections.

    T2DM Diagnostic Evaluation

    • Laboratory diagnostics include clinical evaluation, fasting plasma glucose (FPG), random plasma glucose (RPG), HbA1c, C-peptide, and insulin levels.
    • HbA1c is a measure of average blood glucose over the prior 6-12 weeks.
    • FPG and HbA1c are preferred for diagnosis due to convenience.

    T2DM Treatment

    • The treatment goals for T2DM are to eliminate hyperglycemic symptoms, reduce/eliminate long-term microvascular/macrovascular complications, and allow patients to achieve as normal a lifestyle as possible.
    • The first-line treatment involves diet and exercise (plus metformin).
    • Psychosocial counseling is essential for patients with T2DM.

    Monogenic Diabetes (Maturity-Onset Diabetes of the Young - MODY)

    • MODY is a single gene disorder characterized by genetic defects of pancreatic beta cell function.
    • MODY is a non-insulin-requiring diabetes, but some forms may require insulin.
    • The age of onset for MODY is typically under 25 years of age.
    • MODY is an autosomal dominant disorder with multiple gene abnormalities on different chromosomes.

    Polycystic Ovarian Syndrome (PCOS)

    • PCOS is the most common endocrine disorder in women of reproductive age, affecting 5–10%.
    • PCOS causes menstrual irregularity and androgen excess.
    • PCOS does not have a clear cause, but multiple systems are likely involved.
    • PCOS symptoms include hirsutism, irregular menses, and polycystic ovarian morphology on transvaginal ultrasound.

    PCOS Etiology

    • The etiology of PCOS is unknown, but several theories exist, including:
      • Hypothalamic-pituitary axis defect leading to increased amplitude and frequency of LH pulses, resulting in increased gonadal androgens.
      • Intrinsic ovarian defect leading to androgen overproduction and anovulation.
      • Defects in insulin sensitivity, causing insulin resistance and hyperinsulinemia.

    PCOS Risk Factors

    • PCOS is inherited as a common complex disorder with multiple genes involved.
    • Premature adrenarche (before age 8 in girls) is a risk factor for PCOS.

    PCOS Signs & Symptoms

    • Menstrual dysfunction: Delayed menarche, oligomenorrhea, amenorrhea.
    • Hyperandrogenism: Hirsutism, acne, male pattern hair loss, elevated androgens.
    • Polycystic ovaries: Seen on transvaginal ultrasound.
    • Metabolic/Cardiovascular risks: Overweight/obesity, insulin resistance, T2DM, CAD, sleep apnea, nonalcoholic fatty liver disease.
    • Mood: Linked to depression, anxiety, impaired quality of life, eating disorders.

    PCOS Differential Diagnosis

      • Polycystic ovaries (by ultrasound).
    • Serum total testosterone: Measured if evidence of androgen excess.
    • DHEAS: Measured for symptoms of severe hyperandrogenism.
    • Androstenedione: Role unclear in PCOS evaluation.
    • Serum 17-hydroxyprogesterone: Measured in the early follicular phase to rule out CAH due to 21-hydroxylase deficiency.
    • FSH & estradiol: High in premature ovarian insufficiency.
    • TSH: Check for thyroid abnormalities.
    • Prolactin: Elevated prolactin levels may indicate a pituitary adenoma.
    • Cushing syndrome: If suspected, perform a 24-hour urine cortisol or dexamethasone test.
    • Transvaginal ultrasound (TVUS): Used to check for polycystic ovarian morphology (PCOM).

    Hirsutism

    • Hirsutism is excessive male pattern hair growth in women of reproductive age.
    • Hirsutism affects 5-10% of females of reproductive age.
    • PCOS is the most common cause of hirsutism.
    • Hirsutism can occur with virilization, which is characterized by male pattern alopecia, voice deepening, increased muscle bulk, and clitoromegaly.

    Hirsutism Etiology

    • Hirsutism can be idiopathic or caused by various factors, including:
      • Nonclassical adrenal hyperplasia.
      • Females with virilization or severe hyperandrogenemia.
      • Uncommon causes: hyperprolactinemia, acromegaly, hypothyroidism, severe insulin resistance, medications.

    Hirsutism Clinical Presentation

    • Mild-moderate hirsutism with regular menses and no clear cause can indicate idiopathic hirsutism.
    • Hirsutism with acne, male pattern alopecia, acanthosis nigricans, obesity, and/or oligomenorrhea may indicate PCOS, CAH, or other conditions.

    Hirsutism Diagnostic Evaluation

    • Idiopathic hirsutism: Total testosterone is usually normal.
    • PCOS: Total testosterone is usually elevated.
    • Androgen-secreting tumor: Total testosterone is elevated ≥ 2x normal values.

    Hirsutism Treatment

    • Treatment involves addressing the underlying cause, blocking the androgen response, blocking hair growth, and hair removal.

    Hirsutism Urgent Considerations

    • Rapid virilization necessitates evaluation for tumors, including an adrenal gland CT and an ovarian transvaginal ultrasound.

    Diabetes Mellitus

    • Type 1 Diabetes Mellitus (T1DM) is an autoimmune disease characterized by the destruction of pancreatic beta cells, leading to absolute insulin deficiency.
    • Type 2 Diabetes Mellitus (T2DM) is a metabolic disorder characterized by insulin resistance and a progressive decline in beta cell function, leading to hyperglycemia.
    • Gestational Diabetes (GDM) is a condition that develops during pregnancy characterized by insulin resistance brought on by the hormonal changes in pregnancy.
    • Latent Autoimmune Diabetes in Adults (LADA) is a slowly progressing form of autoimmune diabetes where the body slowly destroys beta cells resulting in a gradual decline in insulin production.
    • Monogenic Diabetes (Maturity Onset Diabetes of the Young (MODY)) is a rare form of diabetes caused by a single gene mutation affecting beta cell function.

    Type 1 Diabetes Mellitus (T1DM)

    • T1DM typically presents in childhood or adolescence, but can occur at any age.
    • T1DM is often characterized by rapid weight loss, polyuria, polydipsia, and polyphagia.
    • T1DM requires lifelong insulin therapy to control blood glucose levels.

    Type 2 Diabetes Mellitus (T2DM)

    • T2DM is the most common type of diabetes, accounting for 90-95% of all cases.
    • T2DM is often associated with obesity, family history, and physical inactivity.

    Gestational Diabetes (GDM)

    • GDM typically develops in the second or third trimester of pregnancy.
    • GDM is often a temporary condition that resolves after delivery.
    • GDM can increase the risk of complications for both the mother and the baby, including macrosomia (large for gestational age), shoulder dystocia, and birth defects.

    Latent Autoimmune Diabetes in Adults (LADA)

    • LADA is a slowly progressing form of autoimmune diabetes, often mimicking type 2 diabetes.
    • LADA can initially be managed with oral medications, but it eventually requires insulin therapy.

    Monogenic Diabetes (Maturity Onset Diabetes of the Young (MODY))

    • MODY is caused by a single gene mutation that disrupts beta cell function.
    • MODY is often diagnosed in younger adults and can sometimes be managed with oral medications.

    MODY Subtypes

    • Glucokinase (GCK) mutation : This subtype causes mild asymptomatic stable fasting hyperglycemia. Treatment is generally not required.
    • Hepatocyte nuclear factor mutations: These subtypes can lead to more severe hyperglycemia and potential complications. Treatment may include sulfonylureas or insulin therapy.

    Management of Diabetes Mellitus

    • Blood Glucose Monitoring: Essential for monitoring blood sugar levels and adjusting treatment plans.

      • Roux-en-Y Gastric Bypass: 50% of initial body weight loss, with an average of 50% weight regain by 5 years.

    Hirsutism

    • Hirsutism is excessive male-pattern hair growth in women of reproductive age.
    • Prevalence: Affects 5-10% of females of reproductive age.
    • Most common cause: Polycystic ovary syndrome (PCOS)
    • Hirsutism Epidemiology:
      • Prevalence: 20% of American women experience hirsutism.
      • Androgen Excess: 80% of women with androgen excess (not all) have hirsutism.
      • Ethnic Variation:
        • East Asian and Native American women tend to have less body hair.
        • Southern European women (Mediterranean) often have more body hair.
    • Hirsutism and Virilization:
      • Virilization: Presence of male-pattern hair loss, voice deepening, increased muscle bulk, and clitoromegaly.
      • Cause: Moderate to severe androgen excess.
    • Hirsutism Etiology:
      • Idiopathic Hirsutism:
        • Women with hirsutism, normal androgen concentrations, and no menstrual irregularities.
        • No identifiable cause for the hirsutism.
      • Androgen Hair Follicle Sensitivity:
        • Hirsutism results from the interplay of circulating serum androgens, hair follicle sensitivity to these androgens, and local growth factors.
        • Key Androgens: Testosterone (primarily from ovaries), Dehydroepiandrosterone sulfate (DHEAS) (from adrenal glands), Androstenedione (from adrenal or ovarian sources).
        • Hair Growth:
          • Hair growth on the scalp, eyebrows, and eyelashes occurs without the influence of androgens.
          • Androgens stimulate hair growth in other body regions (face, arms, legs, trunk).
          • Androgens lead to larger follicles, thicker hair, and a longer growth (anagen) phase.
          • Excess androgens in women promote hair growth in sensitive areas (lip, chin, back).
          • Scalp hair loss occurs due to a shorter growth (anagen) phase in androgen excess.
      • Nonclassical Adrenal Hyperplasia:
        • Characterized by excess androgens (observed in congenital adrenal hyperplasia).
        • Usually recognized at birth or early infancy.
        • Nonclassical form (primary 21-hydroxylase deficiency) presents as:
          • Hirsutism, menstrual irregularities, or primary amenorrhea at puberty.
          • No cortisol deficiency.
      • Females with Virilization or Severe Hyperandrogenemia:
        • Rapid Virilization: Sudden onset of masculine traits in women, frequently caused by excessive adrenal androgens.
        • Common Causes: Androgen-secreting tumors (ovarian, adrenal) or ovarian hyperthecosis.
          • Ovarian Hyperthecosis: Hyperplasia of thecal cells in the ovaries leads to excessive testosterone, resulting in hirsutism and virilization.

    Polycystic Ovary Syndrome (PCOS)

    • PCOS is a common hormonal disorder affecting women of reproductive age.
    • Characteristics:
      • Ovarian Cysts: Multiple small cysts develop on the ovaries.
      • Hormonal Imbalances: Increased levels of androgens (male hormones) and insulin resistance (difficulty using insulin to regulate blood sugar).
      • Other Features: Irregular periods, acne, excess hair growth (hirsutism), weight gain, difficulty conceiving.
    • Diagnosis:
      • Rotterdam Criteria: Requires at least two of the following:
        • Oligomenorrhea or Irregular Menstrual Cycles: Infrequent or irregular periods, or absence of menstruation.
        • Clinical and/or Biochemical Signs of Hyperandrogenism:
          • Clinical: Hirsutism, acne, or alopecia (hair loss).
          • Biochemical: Elevated testosterone levels.
        • Polycystic Ovaries: Multiple follicles in the ovaries on ultrasound.
    • PCOS Testing:
      • Pelvic Ultrasound:
        • Diagnosis:
          • At least twelve follicles in either ovary, measuring 2-9 millimeters in diameter, or an ovarian volume greater than 10 cubic centimeters.
      • Basal Body Temperature Chart:
        • Purpose: To detect the absence of a biphasic pattern, indicating anovulation (lack of ovulation).
        • Current Use: Rarely used in clinical practice.
      • Other Considerations:
        • Blood Pressure, BMI, and Waist Circumference: Indicators of cardiovascular disease risk.
        • Fasting Lipid Profile: Assesses cholesterol levels.
        • 2-hour Oral Glucose Tolerance Test (OGTT) or Fasting Glucose and HbA1c: Detects glucose issues.
        • Screen for Obstructive Sleep Apnea (OSA):
        • Liver Enzymes: (Ultrasound not recommended for screening fatty liver).
        • Screen for Depression and Anxiety Disorders:

    PCOS Treatment

    • Obesity:
      • Weight loss and exercise can reverse metabolic issues and induce ovulation.
    • Non-pregnancy Patients:
      • First-Line Treatment:
        • Combined Hormonal Oral Contraceptives (OCPs): For hyperandrogenism (excess androgens) and menstrual irregularities.
      • Alternatives:
        • Intermittent or Continuous Progestin Therapy: For endometrial protection (lining of uterus)
        • Hormonal Intrauterine Device (IUD): For endometrial protection.
      • Metformin:
        • Mechanism of Action: Improves insulin sensitivity.
        • Benefits: May improve menstrual function, but does not typically impact hirsutism, acne, or infertility.
        • Use: Considered second-line therapy for glucose issues.
      • Medroxyprogesterone (Provera) (10 mg orally daily for the first 10 days of each month):
        • Purpose: Initiates and regulates menses.
        • Limitation: Does not inhibit androgen excess.
      • Low-Dose Combination OCPs:
        • Progestins: Use progestins with low androgenic activity.
        • Benefits: Regulates menses and may decrease androgens while preventing pregnancy.
    • Patients Desiring Pregnancy:
      • Ovary Stimulation:
        • Letrozole: First-line treatment.
        • Clomiphene: Another ovulation-inducing medication.
        • Increased Risk: Increased risk of twins with ovary stimulation.
    • Hirsutism Treatment:
      • Low-Dose Combination OCPs: For 6-12 months.
      • Spironolactone (25 mg orally three times daily):
        • Additional Treatment: If OCPs do not sufficiently improve hirsutism.
        • Contraceptive Requirement: Must be used in conjunction with contraception.
      • Topical Eflornithine (Vaniqa) Cream: Applied to the face twice daily for 6 months.
      • Electrolysis or Laser Therapy: As needed.

    PCOS Prognosis

    • Insulin Resistance and Hyperinsulinemia: Increased risk of developing type 2 diabetes.
    • Anovulation: Lack of ovulation can lead to unopposed estrogen, increasing the risk of endometrial cancer.
    • Pregnancy: A live birth rate of 20-40% with clomiphene treatment.

    Urination & Thirst

    • Prolonged undetected/untreated urinary or cardiovascular abnormalities can signify a health concern.
    • Chronic skin infections and yeast infections can indicate immune system dysfunction.
    • Increased centripetal fat distribution is a sign of metabolic abnormalities:
      • Men: Waist circumference greater than 40 inches.
      • Women: Waist circumference greater than 35 inches.
    • Acanthosis nigricans (darkening of skin with folds and skin tags) is associated with significant insulin resistance.
    • Eruptive xanthomas are associated with hyperchylomicronemia (increased triglycerides).

    T2DM Screening & Diagnosis

    • Many individuals with T2DM are asymptomatic and unaware of the condition.
    • Screening for T2DM is crucial to prevent complications and progression of the disease.
    • Early intervention leads to superior outcomes.
    • Diagnosis of prediabetes warrants increased efforts for diabetes prevention.
    • Cost-effectiveness justifies screening.
    • Recommended screening for T2DM:
      • Individuals overweight or obese, with at least one risk factor: family history of diabetes, certain ethnicities (African American, Latino, Asian), hypertension, low HDL or high triglycerides, PCOS or acanthosis nigricans, history of heart disease, physical inactivity, insulin resistance (severe obesity).
      • Yearly screening for those previously diagnosed with high blood sugar (IFG, IGT, A1C 5.7-6.4%).
      • Every three years for women with past gestational diabetes.
      • Starting at age 45, every three years for everyone.
      • Screening for individuals with HIV.
    • Three broad categories for glucose tolerance: normal glucose homeostasis, impaired glucose homeostasis, and diabetes mellitus.
    • T2DM diagnosis in non-pregnant individuals is based on any one of four abnormalities:
      • Elevated fasting plasma glucose (FPG).
      • Random elevated glucose with symptoms.
      • Elevated HbA1c.
      • Abnormal oral glucose tolerance test (OGTT).
    • Plasma/serum glucose is a more accurate measure of glucose concentration in body tissues compared to blood glucose, as it avoids interference from red blood cell concentration (hematocrit).
    • Concentration of glucose in plasma/serum is typically 10-15% higher than in whole blood.
    • Glycosylated Hb (HbA1c):
      • Glucose irreversibly attaches to the beta chain of HbA.
      • HbA1c levels reflect average blood glucose over the prior 6-12 weeks.
      • More heavily influenced by glucose levels in the prior four weeks.
      • Increased HbA1c predicts the risk of microvascular complications.
      • Not suitable for populations with a high prevalence of hemoglobinopathies or conditions with increased red cell turnover.
    • Oral glucose tolerance test (OGTT)
      • Consume 150-200 g of carbohydrates per day for three days preceding the test.
      • Nothing by mouth (NPO) past midnight prior to the test day.
      • Perform the test in the morning to avoid diurnal variation in glucose tolerance.
      • Administer 75 g of glucose in 300 mL of water orally, consumed within five minutes.
      • Obtain plasma glucose levels at 0 hours (fasting) and 2 hours.
      • Most commonly used in pregnancy.
    • Urine Tests:
      • Urine glucose: Urine dipstick for glucose detects >100 mg/dL of glucose.
      • Urine & blood ketones: Urine dipstick aids in early detection of ketoacidosis, but does not detect beta-hydroxybutyric acid (the primary ketone in DKA). It cannot confirm DKA, but can estimation ketonuria; blood evaluation required to assess for significant ketones.
    • T2DM diagnosis confirmation:
      • If there is no clear symptomatic hyperglycemia, confirm the diagnosis by repeating the same test on a different day or performing two confirmatory tests on the same day.
      • Preferred tests due to convenience: fasting plasma glucose (FPG) and HbA1c.

    T2DM Treatment

    • Treatment goals: eliminate hyperglycemia symptoms, reduce/eliminate long-term micro/macrovascular complications of DM, and enable the patient to achieve as normal a lifestyle as possible.
    • First-line treatment: Diet and exercise (plus metformin).
      • 5-10% weight loss is associated with significant improvement in cardiac risk factors.
      • Diet: Decreased carbohydrate intake to promote decreased triglycerides and increased HDL.

    Gestational Diabetes

    • High glucose levels can cause polyhydramnios (increased amniotic fluid).
    • Increased risk of stillbirth with GDM and suboptimal glucose control.

    Gestational Diabetes Complications

    • Maternal complications:
      • Maternal hypoglycemia, diabetic coma, ketoacidosis.
      • Maternal cardiac, renal, ophthalmic, and peripheral vascular injuries.
    • Neonatal morbidity:
      • Increased risk of hypoglycemia, hyperbilirubinemia, hypocalcemia, hypomagnesemia, polycythemia, respiratory distress, and/or cardiomyopathy.
      • Delayed pulmonary, hepatic, and neurologic organ maturity.
      • Congenital defects: heart, neural tube, renal.
      • Abnormal fetal heart rate patterns.
      • Intrauterine fetal growth retardation and intrauterine fetal distress.
    • Maternal infection.

    Gestational Diabetes Long-Term Consequences

    • GDM is a strong marker for maternal development of T2DM, including diabetes-related vascular disease.
    • GDM increases the offspring's risk of developing obesity, impaired glucose tolerance, and diabetes.

    Gestational Diabetes Risk Factors

    • Personal history of impaired glucose tolerance, HbA1c > 5.7.
    • Family history of diabetes, especially first-degree relatives.
    • Pre-pregnancy BMI > 30, weight gain in early adulthood, between pregnancies, or between 18 and 24 weeks of pregnancy.
    • Older maternal age > 40.

    Gestational Diabetes Screening

    • Obtain HbA1c as part of prenatal laboratory studies at the initial visit. Manage as diabetic if > 6.5%.
    • Targeted screening at 24-28 weeks gestational age with an oral one-hour glucose tolerance test (OGCT).
      • 50-g 1-hr oral glucose challenge test (OGCT) without prior oral intake restrictions (50 g for screening, 100 g for diagnosis).
      • 1-hr serum glucose > 140 mg/dL is abnormal and requires a 3-hr OGTT.
      • 1-hr serum glucose > 200 mg/dL is indicative of GDM, and the 3-hr OGTT is not performed.
    • 3-hr OGTT (if the screening is abnormal, after an overnight fast).
      • Fasting blood sugar (FBS) obtained prior to the start of the test.
      • 100 g oral glucose load.
      • Two or more abnormal values indicate GDM.

    Gestational Diabetes Management

    • Team approach: Patient, obstetrician, maternal-fetal medicine specialist, nutritionist.
    • Goal: Euglycemia.
      • FBS < 95 mg/dL.
      • 1-hr postprandial < 140 mg/dL.
      • 2-hr postprandial < 120 mg/dL.

    Metabolic Syndrome

    • Insulin resistance and hyperglycemia are treated with Metformin, Pioglitazone, and Rosiglitazone.
    • Dyslipidemia is treated with Statins and other lipid-lowering drugs.
    • Hypertension is treated with lifestyle modification and antihypertensive medications.
    • Low-dose aspirin (81 mg orally daily) may be considered: weigh the risk of bleeding against the potential benefit.
    • Metabolic syndrome increases the risk of a pro-thrombotic and pro-inflammatory state, making individuals more susceptible to atherosclerosis and cardiovascular events.
    • Clinical implications of metabolic syndrome:
      • Fatty liver disease (steatosis, fibrosis, and cirrhosis).
      • Hepatocellular carcinoma and intrahepatic cholangiocarcinoma.
      • Chronic kidney disease (CKD = GFR < 60 mL/min per 1.73 m2).
      • Polycystic ovary syndrome.
      • Male hypogonadism.
      • Sleep-disordered breathing, including obstructive sleep apnea (OSA).
      • Hyperuricemia and gout.
      • Increased risk of cognitive decline and dementia.

    Obesity

    • BMI: A measure of excess adipose tissue; weight (kg)/height (m)2.
    • BMI Classifications:
      • 18.5-24.9 = Normal.
      • 25-29.9 = Overweight.
      • 30-34.9 = Class I obesity.
      • 35-39.9 = Class II obesity.

      • 40 = Extreme obesity.

    • BMI does not differentiate between muscle and fat.
    • A BMI range of 18.5-24.99 is generally considered healthy, but individual health can vary outside this range.
    • Increased risk associated with obesity:
      • Hypertension.
      • Diabetes.
      • Dyslipidemia.
      • Obstructive sleep apnea.
      • Nonalcoholic fatty liver disease.
      • Some malignancies.
    • Centripetal obesity (waist circumference > 40 inches in men, > 35 inches in women) leads to increased risk of diabetes, stroke, coronary artery disease, and early death.
    • Upper body obesity (abdomen and flanks) poses greater health risks than lower body obesity (buttocks and thighs).

    Obesity Epidemiology

    • American adults:
      • 30.7% are overweight.
      • 42.4% are obese, including severe obesity.
      • 60% of individuals with obesity suffer from metabolic syndrome.
      • 40-70% of obesity is attributed to genetic influences.
      • Less than 1% experience secondary obesity (hypothyroidism, Cushing's syndrome).
    • Prevalence has increased over the past three decades, especially among those aged 20-60 years (peaks at 60, then slightly declines).

    Obesity Patient Evaluation

    • Focused History:
      • Factors contributing to the patient's obesity.
      • How obesity affects the patient's health.
      • The patient's level of risk from obesity.
      • The patient's difficulties in managing weight.
      • The patient's goals and expectations.
      • The patient's motivation to start a weight management program.
      • The type of assistance the patient requires.
    • Physical exam to determine the degree and type of obesity.
    • Assessment of comorbid conditions.
    • Determination of fitness level.
    • Assessment of the patient's readiness to adopt lifestyle changes.
    • History and Physical:
      • Family history of obesity (if negative, look for extraneous causes).
      • Weight gain history over time (recent vs. chronic).
      • Diet and exercise routine (sedentary vs. active vs. athletic).
      • Degree and distribution of body fat (increased health risks with centripetal obesity).
      • Signs of secondary obesity:
        • Cushing's syndrome (round face, buffalo hump, striae).
        • Hypothyroidism (depression, fatigue, constipation, cold intolerance, etc.).

    Hirsutism

    • Excessive male-pattern hair growth in women of reproductive age.
    • Affects 5-10% of females of reproductive age.
    • The most common cause is polycystic ovary syndrome (PCOS).

    Hirsutism Epidemiology

    • 20% of American women experience hirsutism.
    • 80% of women with androgen excess exhibit hirsutism (but not all women with hirsutism have excess androgens).
    • The extent of terminal hair growth varies by ethnic background:
      • East Asian and Native American women: Less body hair.
      • Southern European women (Mediterranean): More body hair.
    • Hirsutism can sometimes occur with virilization:
      • Male pattern alopecia, voice deepening, increased muscle bulk, clitoromegaly.
      • Virilization represents moderate to severe androgen excess.

    Hirsutism Etiology

    • Idiopathic Hirsutism:
      • Females with hirsutism, normal androgen concentrations, no menstrual irregularities, and no identifiable cause.
    • Hirsutism results from the interaction of circulating serum androgens, hair follicle sensitivity to those androgens, and local growth factors.
    • Key androgens:
      • Testosterone: Primarily from the ovaries.
      • Dehydroepiandrosterone sulfate (DHEAS): From the adrenal glands.
      • Androstenedione: From adrenal or ovarian sources.
    • Hair growth on the scalp, eyebrows, and eyelashes does not require androgens.
    • Androgens increase hair growth in other body areas (face, arms, legs, trunk).
      • Androgens lead to larger follicles, thicker hair, and a longer growth (anagen) phase.
      • Excess androgens in females cause hair growth in sensitive areas (lip, chin, back).
      • Scalp hair loss occurs due to a shorter growth (anagen) phase in androgen excess.
    • Nonclassical Adrenal Hyperplasia:
      • Characterized by excess androgens (seen in congenital adrenal hyperplasia).
      • Usually recognized at birth or early infancy.
      • The nonclassical form (primary 21-hydroxylase deficiency) presents as:
        • Females with hirsutism at puberty, menstrual irregularities, or primary amenorrhea.
        • No cortisol deficiency.
    • Females with Virilization or Severe Hyperandrogenemia:
      • Rapid virilization: Sudden onset of masculine traits in females, often from excess adrenal androgens.
      • Common causes: Androgen-secreting tumors (ovarian, adrenal) or ovarian hyperthecosis.
        • Ovarian hyperthecosis: Thecal cell hyperplasia in ovaries leads to excess testosterone, causing hirsutism and virilization.

    Autonomic Neuropathy

    • Generalized - ataxia, gait instability
    • Gastrointestinal - constipation (most common manifestation), dysphagia, abdominal pain, nausea, vomiting, diarrhea, fecal incontinence, gastroparesis
      • Gastroparesis may lead to poor glucose control.
      • Treatment includes diet changes and prokinetic agents (erythromycin, cisapride, domperidone).
      • Anti-emetics can be used for treatment.
      • Metoclopramide is used for severe cases only.
    • Cardiovascular - persistent sinus tachycardia, orthostasis, exercise intolerance
    • Genitourinary - Bladder neuropathy (poor urinary stream/straining, feeling of incomplete emptying, recurrent UTIs, pyelonephritis, incontinence), erectile dysfunction, retrograde ejaculation
    • Sudomotor Neuropathy - Heavy sweating of the upper body and anhidrosis (lack of sweat) of the lower body, gustatory sweating

    Hyperosmolar Hyperglycemic State (HHS)

    • Second most common form of hyperglycemic coma and a serious acute complication
    • It is a severe hyperglycemia in the absence of significant ketoacidosis.
    • There is hyperosmolality and dehydration leading to altered mental status.
    • Etiology: type 2 diabetes mellitus (T2DM) plus illness with fluid intake, but no ketoacidosis.
    • Pathophysiology: Decreased insulin -> Increase in counterregulatory hormones -> Decreased glucose utilization and increased gluconeogenesis -> Hyperglycemia -> Osmotic diuresis -> Dehydration -> Limited access to water, so the body holds onto water -> Hyperosmolar state
    • Signs/Symptoms: Develops over weeks to days, polyuria (+/- polydipsia), weight loss, weakness, tachycardia, hypotension, dry skin and mucous membranes, poor skin turgor, altered mental status without Kussmaul respirations

    Nonketotic Hyperosmolar State

    • Diagnosis: Plasma glucose > 600, serum osmolality > 320 (normal = 280-290), profound dehydration up to an average of 9 liters.
    • Blood urea nitrogen (BUN)/creatinine is elevated due to dehydration -> poor perfusion.
    • There is no significant acidosis (serum pH > 7.3, bicarbonate concentration > 15, small ketonuria and absent-to-low ketonemia).
    • May have some ketosis due to lack of eating.
    • Treatment: Rehydration, correction of hyperglycemia, treatment of underlying illness. May require insulin.

    Type 2 Diabetes Mellitus Wrap-Up

    • Every patient with T2DM needs:
      • Multidisciplinary team working with both the patient and the patient’s family.
      • A written plan that encompasses medications, diet/exercise, and goal setting.
      • Medications (with adequate refills). Most patients with T2DM are on multiple medications.
      • Education on using devices to calculate whether individuals are overweight or underweight.

    Body Mass Index (BMI)

    • BMI does not distinguish between muscle and fat.
    • BMI 18.5 – 24.99 = considered to be healthy.
    • Some people are healthy with other BMIs.
    • Some people are unhealthy in this BMI range.

    • Increased risk of:
      • Hypertension
      • Diabetes
      • Dyslipidemia
      • Obstructive sleep apnea
      • Nonalcoholic fatty liver disease
      • Some malignancies
    • Centripetal obesity (>40 inches in men, >35 inches in women) leads to an increased risk of diabetes mellitus, stroke, coronary artery disease, and early death.
    • Upper body obesity (abdominal and flank) = greater health risk vs. lower body (buttocks and thighs) obesity.

    Obesity Epidemiology

    • American adults:
      • 30.7% = overweight
      • 42.4% = obese
      • 9.2% = severe obesity
      • 60% with obesity have metabolic syndrome
      • 40-70% of obesity = genetic influences
      • < 1% = secondary obesity (hypothyroidism, Cushing syndrome)
    • Increased prevalence over the last 3 decades, especially with ages 20-60 years old (peaks at 60 then slightly declines).

    Obesity Patient Evaluation

    • Focused history:
      • History considerations:
        • What factors contribute to the patient’s obesity?
        • How is the obesity affecting the patient’s health?
        • What is the patient’s level of risk from obesity?
        • What does the patient find difficult about managing weight?
        • What are the patient’s goals and expectations?
        • Is the patient motivated to begin a weight management program?
        • What kind of help does the patient need?
    • Physical exam to determine the degree and type of obesity
    • Assessment of comorbid conditions
    • Determination of fitness level
    • Assessment of the patient’s readiness to adopt lifestyle changes

    Obesity History and Physical Examination

    • Family history of obesity. If negative, search for extraneous causes.
    • Weight gain history:
      • Recent vs. chronic.
    • Diet and exercise routine:
      • Sedentary vs. active vs. athletic.
    • Degree and distribution of body fat: Increased health risks with centripetal obesity.
    • Signs of secondary obesity:
      • Cushing syndrome - round face, buffalo hump, striae.
      • Hypothyroidism - depression, fatigue, constipation, cold intolerance, etc.

    Obesity Diagnostic Evaluation

    • Measurements:
      • Blood pressure.
      • Weight and height -> Calculate BMI.
      • Waist circumference.
    • Labs:
      • Thyroid-stimulating hormone (TSH) and Free T4.
      • Fasting lipid panel.
      • Fasting glucose.

    Obesity Differential Diagnosis

    • Increased caloric intake (life changes).
    • Fluid retention (heart failure, cirrhosis, renal failure).
    • Hypothyroidism.
    • Diabetes mellitus (type 2).
    • Drugs (antipsychotics, antidepressants, corticosteroids).
    • Insulinoma.
    • Binge eating disorder.

    Obesity Treatment

    • Primary approach (if no underlying condition): Diet and exercise.
    • Goal: Decrease in 10% body weight over 6 months or 1-2 pounds per week.
    • Reassess treatment plan after 6 months.

    Obesity Diet

    • General guidelines for weight loss:
      • Aim for a 500-750 kcal/day deficit from habitual diet.
      • For women: Consume 1200-1700 kcal/day.
      • For men: Consume 1500-1800 kcal/day.
      • Caloric intake should be adjusted based on the individual’s body weight.
    • No single diet is proven superior for long-term weight loss (>1 year). Mediterranean diet may reduce atherosclerotic cardiovascular disease (ASCVD) risk.
    • Low-carb, high-protein diets show increased weight loss at 6 months.

    Obesity Exercise

    • Best approach - Combine diet and exercise for effective long-term weight loss.
      • Exercise alone is usually not enough for maintaining weight loss beyond 1 year.
    • Physical Activity Guidelines:
      • 150 minutes of moderate-intensity or 75 minutes of vigorous activity per week performed for at least 10 minutes and spread throughout the week.
    • Simple activities: Brisk walking, using stairs, housework, and sports.
      • Pedometers or accelerometers can be used to track steps and activity.
      • Step counts are highly correlated with overall activity level.

    Obesity Adjunctive Behavioral Therapy

    • Cognitive behavioral therapy (CBT) strategies to help change and reinforce new dietary and physical activity behaviors.
    • Self-monitoring techniques (e.g., journaling, weighing, and measuring food and activity), stress management, stimulus control (e.g., using smaller plates, not eating in front of the television or in the car), social support, problem-solving, and cognitive restructuring to help patients develop more positive and realistic thoughts about themselves.

    Obesity Adjunctive Pharmacological Treatment

    • Considered for patients with:
      • BMI ≥ 30 kg/m2.
      • BMI ≥ 27 kg/m2 with concomitant obesity-related disease and when dietary and physical activity therapy has not been successful.
    • Gastrointestinal (GI) fat blockers - Orlistat (Xenical, Alli) (120 mg PO TID with meals).
      • 5% body weight loss.
      • Mechanism of action (MOA): Decreases fat absorption in the gastrointestinal tract (GIT).
      • Side effects: May cause GI distress (diarrhea, cramping, flatulence).
        • Low fat diet reduces symptoms, which can motivate the patient to stay on diet.
    • Appetite suppressants (anorexiants):
      • Lorcaserin (Belviq) (10 mg PO BID):
        • 5% body weight loss.

    • Mortality: 1% risk in the postoperative period, higher rate within the first year after surgery.
    • Multidisciplinary approach: Diet, exercise, behavioral modification, social support, pre-meal planning.

    Obesity Outcomes and Prognosis

    • Hypertension and hyperlipidemia.
    • Coronary artery disease.
    • Type 2 diabetes mellitus.
    • Degenerative joint disease.
    • Psychosocial disability.
    • Increased cancers (colon, rectum, prostate, uterus, biliary tract, breast, ovary).
    • Thromboembolic disorders (myocardial infarction, stroke, pulmonary embolism).
    • Digestive tract diseases (gallstones, reflux esophagitis).
    • Skin disorders (hidradenitis suppurativa, striae, acanthosis nigricans, delayed wound healing, infections).
    • 20% lose 20 pounds.

    Hirsutism

    • Excessive hair growth in women in male-pattern distribution (face, chest, abdomen, back).
    • It is a common symptom of androgen excess.
    • Most common causes include:
      • Polycystic ovary syndrome (PCOS).
      • Idiopathic hirsutism.
      • Ovarian hyperthecosis.
      • Androgen-secreting tumors.
      • Nonclassic congenital adrenal hyperplasia (NCCAH).
      • Other less common causes.

    Ovarian Hyperthecosis

    • Nonmalignant ovarian disorder with increased testosterone from luteinized thecal cells.
    • Testosterone levels are often greater than 700, meaning markedly increased.
    • It is unclear if it is a distinct disorder or part of PCOS.
    • Mostly affects postmenopausal women but can occur in premenopausal women.

    Androgen-Secreting Tumors

    • Usually occurs later in life and progresses rapidly compared to PCOS.
    • Approximately 5% of ovarian tumors.
    • Identified by pathology (biopsy/surgery) or transvaginal ultrasound (TVUS).
    • Most females have testosterone levels >150-200 and present with virilization.
    • Rare cause of androgen excess.
    • Adenomas secrete testosterone.
    • Carcinomas secrete dehydroepiandrosterone (DHEA), DHEA sulfate (DHEAS), and cortisol.
    • Symptoms: Androgen excess, Cushing syndrome.
    • Elevated DHEAS suggests adrenal carcinoma.

    Uncommon Causes of Hirsutism

    • Hyperprolactinemia (pituitary adenoma).
    • Acromegaly (pituitary adenoma).
    • Hypothyroidism.
    • Severe insulin resistance.
    • Drugs: Androgen therapy (testosterone, DHEA), danazol (used to treat endometriosis).

    Hirsutism Clinical Presentation

    • Mild to moderate hirsutism:
      • Regular menses, no clear cause -> Idiopathic hirsutism.
    • Hirsutism with:
      • Acne, male pattern alopecia, acanthosis nigricans, obesity, and/or oligomenorrhea -> Think PCOS.
      • Increased cortisol and/or androgens.
    • Increased prolactin (PRL): Galactorrhea, vision changes, infertility, oligo/amenorrhea.
    • Congenital adrenal hyperplasia (CAH): Menstrual abnormalities, virilization, increased DHEA/DHEAS/androstenedione.
    • Androgen-secreting tumor: Older age, rapid progression, virilization.
    • Ovarian hyperthecosis: Older age, intense slow-progressing hirsutism.

    Hirsutism Diagnostic Evaluation

    • Idiopathic hirsutism:
      • Total testosterone = Normal.
    • Polycystic ovary syndrome (PCOS):
      • Total testosterone = usually elevated.
      • Transvaginal US (TVUS).
    • Androgen-secreting tumor:
      • Total testosterone = elevated ≥ 2x normal values.
      • Get DHEAS (primarily adrenal origin) and androstenedione (primarily ovarian origin).
      • Pelvic ultrasound.
      • Computed tomography (CT) of abdomen and pelvis.

    Hirsutism Treatment

    • Treat underlying cause: Remove tumor, block androgen production (Oral contraceptive pills suppress gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) = decreased ovarian androgens).
    • Block androgen response:
      • Spironolactone (androgen antagonist, recommended).
      • Finasteride (inhibits 5-alpha-reductase type 2 - enzyme that converts testosterone to dihydrotestosterone (DHT), concerns about its use inadvertently in pregnancy).
      • Flutamide (non-steroidal androgen receptor antagonist, prostate cancer drug used off label).
      • Antiandrogens contraindicated in pregnancy.
    • Block hair growth: Vaniqa (retards hair growth).
    • Hair removal:
      • Depilatory creams (Nair).
      • Electrolysis, laser ablation.
      • Manual (plucking).

    Hirsutism Urgent Considerations

    • Rapid virilization:
      • Evaluate for tumor.
      • Adrenal gland CT.
      • Ovarian TVUS.

    Polycystic Ovarian Syndrome (PCOS)

    • Most common endocrine disorder in reproductive-age women (5-10%).
    • 90% of hyperandrogenism in women.
    • Prevalence does NOT vary across different regions of the world.
    • Causes menstrual irregularity and androgen excess.
    • Symptoms: Hirsutism, irregular menses, polycystic ovarian morphology on transvaginal ultrasound.

    PCOS Etiology

    • Unknown etiology: Multiple systems involved, primary defect unclear.
    • Theories:
      • Hypothalamic-pituitary axis defect -> Increased amplitude and frequency of luteinizing hormone (LH) pulses -> Increased gonadal androgens.
      • Intrinsic ovarian defect -> Androgen overproduction and anovulation.
      • Defects in insulin sensitivity = insulin resistance -> hyperinsulinemia.
    • Pathophysiology: Not well understood, multiple mechanisms possible.

    PCOS Risk Factors

    • Family history (FHx): PCOS inherited as a common complex disorder (multiple genes involved).
    • Premature adrenarche (before age 8 in girls).

    PCOS Signs/Symptoms

    • Menstrual dysfunction: Delayed menarche, oligomenorrhea (irregular flow), amenorrhea (no menses for 3+ months).
    • Hyperandrogenism: Hirsutism, acne, male pattern hair loss, most have elevated androgens.
    • Hirsutism.
    • Polycystic ovaries: Seen on TVUS.
    • Metabolic/cardiovascular risks:
      • 40-85% are overweight/obese.
      • Insulin resistance, type 2 diabetes mellitus, coronary artery disease, sleep apnea, nonalcoholic fatty liver disease.
    • Mood: Linked to depression, anxiety, impaired quality of life, eating disorders.
    • Symptoms:
      • Hirsutism 60%.
      • Acne 20%.
      • Scalp hair loss 5%.
      • Oligomenorrhea (< 6-8 menses/year).
      • Amenorrhea (no menses).
      • Irregular menses.
      • Weight gain.
      • Infertility.
    • Physical examination:
      • Hirsutism.
      • Acne.
      • Alopecia.
      • Possible hypertension.
      • Acanthosis nigricans.
      • Sweating.
      • Oily skin.

    PCOS Differential Diagnosis

    • Congenital adrenal hyperplasia (CAH) = 21 hydroxylase deficiency - most common cause of congenital adrenal hyperplasia, missing enzyme -> overproduction of adrenal hormones.
    • Thyroid dysfunction.
    • Hyperprolactinemia.
    • Cushing syndrome (rare).
    • Androgen-secreting neoplasm.

    PCOS Diagnostic Evaluation

    • Rotterdam Criteria (Preferred) - 2 of 3 Required -
      • Oligo- and/or anovulation.
      • Clinical and/or biochemical signs of hyperandrogenism.
      • Polycystic ovaries (by ultrasound).
      • Diagnosis confirmed after excluding other conditions (thyroid disease, nonclassic congenital adrenal hyperplasia (NCCAH), hyperprolactinemia, androgen-secreting tumors).
    • Serum total testosterone:
      • Measure if evidence of androgen excess.
      • Upper limit of normal for women is 45-60.
      • Levels > 150 require evaluation for ovarian or adrenal androgen-secreting tumor or ovarian hyperthecosis.
    • DHEAS - not suggested for everyone:
      • Measure for symptoms of severe hyperandrogenism.
      • Can be extremely elevated in patients with adrenal carcinoma.
    • Androstenedione: Role unclear in evaluation of PCOS (mixed results).
    • Serum 17-hydroxyprogesterone:
      • Measure morning level in early follicular phase to rule out congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

      • 800 = adrenal hyperplasia.

    • Follicle-stimulating hormone (FSH) and estradiol: High in premature ovarian insufficiency (also have low estradiol).
    • Thyroid-stimulating hormone (TSH): Check for thyroid abnormalities (also cause irregular menses/ovulation).
    • Increased prolactin: Pituitary adenoma causes irregular menses, ovulation, galactorrhea.
    • Cushing syndrome: If suspected, perform 24-hour urine cortisol or dexamethasone test.
      • Shared symptoms include: Oligomenorrhea, hirsutism, obesity, hypertension, striae, muscle weakness.
    • Transvaginal ultrasound (TVUS): Used to check for polycystic ovarian morphology (PCOM).
      • Not all suspected PCOS patients need ultrasound.
