Study Notes
Diabetes Mellitus
- A metabolic disease where the body's inability to produce enough insulin causes elevated glucose levels.
Types of Diabetes
- Type 1: Usually diagnosed in children and young adults. The body's immune system destroys insulin-producing cells. Not preventable. Approximately 5% of all cases.
- Type 2: Most common form (about 90% of cases). Body produces insulin but does not use it properly. Glucose doesn't move into cells, causing a build-up in the bloodstream. Often preventable.
- Gestational diabetes: Occurs during pregnancy. Increased risk for type 2 diabetes later. 18 out of every 100 pregnant women get GDM.
- Prediabetes: Elevated blood sugar levels, but not high enough for a diagnosis of diabetes. A higher risk of developing type 2 diabetes in the future.
Symptoms of Diabetes
- Excessive thirst and frequent urination
- Increased appetite and unusual weight loss or gain
- Fatigue
- Nausea or vomiting
- Blurred vision
- Frequent yeast or vaginal infections
- Slow-healing sores or cuts
- Skin itching, especially in groin or vaginal area
- Sudden weight loss
- Frequent urination
- Always hungry
- Wounds that won't heal
- Blirry vision
- Sexual problems
- Always thirsty
- Vaginal infections
- Numb or tingling hands or feet
Signs and Symptoms of Type 1 Diabetes
- Polyuria (frequent urination)
- Polydipsia (extreme thirst)
- Polyphagia (extreme hunger)
- Weight loss
- Fatigue
- Increased frequency of infections
- Rapid onset
- Insulin-dependent
- Early onset (often before age 20)
Type 2 Diabetes
- Most common type
- Body produces insulin but doesn't use it properly
- Glucose accumulates in the bloodstream
- Often preventable
Components of Type 2 Diabetes
- Insulin resistance
- Beta-cell dysfunction
Risk Factors
- Genetics
- Family history
- Polycystic ovary syndrome
- Irregular menses
- Race (African Americans, Hispanics, Asians > whites)
- Age (after age 45, but increasingly younger)
- Environmental factors
- Inactivity
- Weight gain
Gestational Diabetes Mellitus (GDM)
- Diabetes during pregnancy
- Family history of diabetes or being overweight before pregnancy
- Giving birth to a baby >9lbs
- 18 out of every 100 pregnant women get GDM
- High blood glucose in mother
- Baby gaining extra weight due to increased glucose in the mother
Complications of Uncontrolled Diabetes
- Heart disease
- Stroke
- Kidney failure
- Blindness
- Nerve damage
- Amputation
- Wound that does not heal
- Cardiovascular disease
- Stroke
- Heart attack
- Loss of circulation in arms and legs
Monitoring Diabetes
- Blood samples taken from a finger prick
- Strips are put into blood glucose meter
- Recording blood glucose levels allows for changes in treatment and lifestyle changes
Prevention of Diabetes
- Type 1: Currently not preventable. Research continues on preventing further beta cell destruction.
- Type 2: Primary prevention involves maintaining a healthy lifestyle (diet and exercise). Secondary prevention involves checking HbA1c (average blood sugar over three months). Tertiary prevention involves ongoing exercise and proper diet.
- Gestational diabetes: Active lifestyle before and after pregnancy can reduce risk by about 70%. Higher fiber diets reduce the risk by 26%.
U.S. Prevalence of Diabetes
- 29.1 million people
- 1 out of every 11 people
- Undiagnosed cases still exist
Global Prevalence of Diabetes
- 387 million people worldwide
- Continued expected increase
Prediabetes
- 86 million people
- 9 out of 10 do not know they have it
- 15-30% may develop type 2 within 5 years
Diabetes Prevention Program (Type 2)
- Lifestyle intervention group vs. medicated group (with Metformin) vs placebo.
- Lifestyle intervention reduced diabetes by 58%.
- Metformin reduced diabetes by 31%.
- Effective for both sexes (25-44 years old) and BMI of 30+.
Treatment of Type 2 Diabetes
- Monotherapy: Usually begin with a healthy lifestyle change.
- Combination Therapy: Often added medication is needed to manage glucose
- Initial treatment depends on individual factors like age, obesity, genetics etc.
- Different drugs (oral/insulin) can be used in treatment
