Anorexia Nervosa
- Characterized by a morbid fear of weight gain and a distorted body image
- Individuals with anorexia nervosa may have an obsessive need to control food intake
- Often involves extreme dieting, fasting, and/or excessive exercise.
- Self-induced vomiting and the misuse of laxatives, diuretics, or enemas may co-occur.
- BMI below 85% of expected weight may indicate severity
- Hypothermia, bradycardia, hypotension, and edema are other symptoms.
- Amenorrhea is a common symptom associated with weight loss in females.
- The disorder often starts in adolescence.
- A subjective concept of one's physical appearance
- The body image is distorted leading to the individual perception of being "fat" when underweight.
Types of Anorexia Nervosa
- Restriction type: involves dieting, fasting, or excessive exercise without episodes of binge and purging
- Binge-eating/purging type: characterized by recurrent episodes of binge eating or purging behavior.
Anorexia Nervosa Severity
- Severity is classified based on BMI: Mild, Moderate, Severe, or Extreme.
Bulimia Nervosa
- An eating disorder characterized by episodes of binge eating (rapid ingestion of large amounts of food) followed by compensatory behaviors
- Compensatory behaviors to rid the body of excess calories often include purging (self-induced vomiting, misuse of laxatives, diuretics, or enemas) or fasting, or excessive exercise.
- Individuals with bulimia nervosa experience feelings of guilt, shame, and depression after binge-eating episodes.
