Study Notes
Eating Disorders: Risk Factors, Pathophysiology, and Clinical Manifestations
-
Anorexia Nervosa (AN):
- Risk Factors: Genetic predisposition, family history of eating disorders or mood disorders, perfectionism, low self-esteem, body dissatisfaction, societal pressure, stressful life events. Typically begins during adolescence or young adulthood.
- Pathophysiology: Hypothalamic-pituitary axis dysfunction, leading to low gonadotropin-releasing hormone, reduced estrogen/testosterone, increased cortisol, neurotransmitter imbalances (low serotonin), and CNS neuropeptide dysregulation (altered neuropeptide-Y and leptin).
- Clinical Manifestations: Extreme weight loss (BMI < 18.5), fear of gaining weight, distorted body image, amenorrhea, fatigue, bradycardia, low blood pressure, and osteopenia/osteoporosis.
-
Bulimia Nervosa (BN):
- Risk Factors: Family history of eating disorders or substance abuse, impulsivity, emotional dysregulation, sociocultural influences, history of trauma or abuse.
- Pathophysiology: Serotonin imbalance, dopamine dysregulation (altering reward processing), hypothalamic-pituitary-adrenal (HPA) axis activation related to stress and emotional eating, and electrolyte imbalances (sodium and potassium depletion from vomiting and laxative use).
- Clinical Manifestations: Normal or slightly overweight body mass, recurrent episodes of binge eating, followed by compensatory behaviors (purging, laxatives, excessive exercise), pitted teeth, esophageal inflammation, swollen salivary glands, electrolyte imbalances (hypokalemia), and irregular heart rhythms.
-
Binge Eating Disorder (BED):
- Risk Factors: Family history of obesity or eating disorders, emotional eating, low self-esteem, stress coping mechanisms, access to high-calorie foods, chronic dieting, and comorbid psychiatric conditions (depression or anxiety).
- Pathophysiology: Dysregulated dopamine signaling, low inhibitory control of food intake, hypothalamic dysfunction, and neuroinflammation.
- Clinical Manifestations: Recurrent episodes of consuming large amounts of food in short time frames, with a lack of control during episodes. No compensatory behaviors. Associated with obesity, type 2 diabetes, hypertension, cardiovascular risks, emotional distress, guilt, and shame after eating episodes.
