Study Notes

Women's Health - Evaluation and Management of Gynecologic Concerns

  • Amenorrhea: Absence or abnormal cessation of menstrual bleeding.

Primary Amenorrhea

  • Characterized by the absence of both spontaneous uterine bleeding and secondary sexual characteristics by age 14.
  • Alternatively, it's the absence of menarche (first menstrual period) by age 16, regardless of secondary sexual development.
  • Half of primary amenorrhea cases stem from a failure of the gonads to develop.
  • Other causes include structural abnormalities (e.g., imperforate hymen, vaginal abnormalities,) and disorders of the hypothalamic-pituitary-ovarian (HPO) axis, malnutrition, and PCOS.

Secondary Amenorrhea

  • Absence of menstruation in a woman who previously had regular periods.
  • Frequent causes are pregnancy, breastfeeding (lactation), weight loss/eating disorders, intense athletic training (e.g., ballet, running) and early menopause.
  • Discontinuation of birth control pills (OCPs) or Depo-Provera can also contribute.
  • Similar to primary amenorrhea, disorders of the HPO axis can also cause secondary amenorrhea.

Types of Secondary Amenorrhea

  • Hyperprolactinemia: Caused by drugs (e.g., OCPs, phenothiazines), pituitary tumors, or systemic illnesses (acromegaly, hypothyroidism). Nipple stimulation and breastfeeding can also elevate prolactin levels.
  • Hyperandrogenism: Often linked to PCOS, obesity, Cushing's syndrome, adrenal or thyroid disorders, or androgen-secreting tumors.
  • Hypogonadotropic Amenorrhea: A result of congenital or acquired disorders affecting the HPO axis. Commonly seen in young women under significant stress—emotional, physical or nutritional deficiencies or eating disorders.

Clinical Presentation - Absent Bleeding

  • Comprehensive menstrual history (age at menarche, frequency, duration, flow, missed periods.)
  • Detailed sexual history (number of partners, last intercourse, birth control methods)
  • Medical history (pregnancies, abortions, ectopic pregnancies, surgical procedures, family history of infertility) and medication history (including OTC and illicit drugs).
  • Nutritional and exercise history (disordered eating habits, recent weight changes, athletic activity levels)
  • Review of other symptoms (e.g., headaches, visual disturbances, galactorrhea, thyroid issues) and social history (stressful life events, substance use).

Physical Exam and Diagnostics

  • Thorough physical exam, focussing on general growth and development, and the assessment of visual acuity, thyroid, pelvic region, and cervical region.
  • Initial laboratory tests: Ruling out pregnancy (serum hCG), assessing hormonal function (FSH, LH), thyroid function (TSH), and prolactin levels.
  • Imaging: MRI or CT scans may be necessary if prolactin levels are high to identify pituitary tumors.

Differential Diagnoses

  • Turner syndrome
  • Abnormal chromosomes
  • Chromosomal deletions
  • Structural abnormalities
  • Malnutrition
  • Systemic illnesses
  • Tumors
  • Early menopause
  • Pregnancy
  • Primary ovarian insufficiency
  • PCOS
  • Medication-related amenorrhea

Management

  • Psychiatric counseling (when indicated), especially for disordered eating behaviors.

  • Medication: Progesterone challenge test if imaging is normal (medroxyprogesterone for 5-7 days), hormonal therapy.

  • Restoration of hypothalamic-pituitary-adrenal axes: Treating conditions like Kallmann syndrome or pituitary lesions, head injuries, or infections which impact the hormonal axis

  • Lifestyle modifications for anorexia nervosa: Increased nutritional intake, weight restoration and reduced exercise to re-establish menstruation.

Hospitalization

  • Necessary for women with anorexia nervosa who have lost more than 30 percent of their desired body weight and fail to gain weight, and those with suicidal ideation.

Dysmenorrhea

  • Primary Dysmenorrhea: Painful menstruation without an identifiable underlying medical condition, most common in adolescents, typically starting 6-12 months after menarche.
  • Secondary Dysmenorrhea: Painful menstruation with an underlying medical condition like endometriosis, PID, or fibroids, typically after childbearing age (30-40s).

Signs and Symptoms (both primary and secondary dysmenorrhea)

  • Cramping and painful menses
  • Lower abdominal pain, possibly worsening during menstruation
  • Back pain, nausea, headache, diarrhea
  • Unilateral pain or signs of acute abdomen suggest more serious underlying issues that require additional medical evaluation.

Laboratory/Diagnostics (Dysmenorrhea)

  • Primary Dysmenorrhea: No specific testing; diagnosis is clinical.
  • Secondary Dysmenorrhea: Testing based on suspected underlying cause (e.g., pelvic exam, hormonal testing).

Management (Dysmenorrhea)

  • Education on menstruation, diet, and lifestyle choices can be beneficial.
  • Heat application like hot water bottles, relaxation techniques, and biofeedback are simple strategies that can support managing painful periods.
  • Over-the-counter pain relievers (NSAIDs, ibuprofen) can provide relief. For severe cases, stronger NSAIDS, or other medications may be considered.
  • Nutritional supplements like B vitamins, zinc, and calcium may play a role in managing pain.
  • Oral contraceptives can regulate the menstrual cycle and reduce cramping.
  • Referral to a specialist is recommended if pain is severe or does not respond to treatment.
