Study Notes on Anorexia Nervosa and its Impact

Eating Disorders: Features and Epidemiology

Overview of common eating disorders:
- Anorexia Nervosa
- Bulimia Nervosa
- Binge-Eating Disorder

Key Characteristics:
- People with anorexia nervosa:
- Refuse to maintain normal body weight
- Experience intense fear of gaining weight
- Have a disturbed body image regarding their shape and weight
Diagnostic criteria as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5):
- A. Restriction of Energy Intake:
- Relative to requirements, leading to significantly low body weight considering age, sex, developmental trajectory, and physical health.
- Definition: Significantly low weight is less than minimally normal or, for children/adolescents, less than minimally expected.
- B. Intense Fear:
- Persistent fear of gaining weight or becoming fat, interfering with weight gain despite being at low weight.
- C. Body Image Disturbance:
- Disturbance in the perception of one's body weight or shape.
- Undue influence of body weight/shape on self-evaluation.
- Persistent lack of recognition of the seriousness of current low body weight.
Specification of Severity:
- Types: Restricting or binge-eating/purging type
- Remission: Partial or full
- Severity:
- Mild: BMI ≥ 17 kg/m²
- Moderate: BMI 16-16.99 kg/m²
- Severe: BMI 15-15.99 kg/m²
- Extreme: BMI < 15 kg/m²

Appetite and Behavior:
- People with anorexia may appear to lack appetite but actually think about food intensively and may prepare meals for others.
Body Image Distortion:
- Sooki's example of losing 25 pounds, yet perceiving herself as fat highlights the extreme body image distortion.
- A metaphor for this distortion is the effect of looking into a fun house mirror, which shows a distorted reflection.
Relation to Weight Loss:
- People typically lose weight by:
- Eating less
- Excessive exercise
- Avoiding high-calorie foods
- Skipping meals
Types of Weight Loss:
- Restricting subtype: Reducing caloric intake and meal skipping
- Binge-eating/purging subtype: Involves binge eating and purging methods, such as self-induced vomiting, misuse of laxatives or diuretics, and enemas.

Background Information:
- Kitty Westin recounts her daughter Anna's journey with anorexia nervosa, which started at 16 years old and led to her eventual suicide at 21.
Symptoms and Behavioral Changes:
- Anna exhibited perfectionism, high achievement, and dissatisfaction with perceived imperfections from a young age
- Development of obsessive thoughts regarding size starting around age 15 after an acquaintance remarked on her thighs.
- Transition from sociable to withdrawn behavior, avoiding family meals and displaying hostility.
- Denial of eating issues earlier in the process.
Family Response and Treatment:
- Difficulty faced by the family in understanding eating disorders and available support; lack of information compared to illnesses like cancer or diabetes.
- Initial treatment included an outpatient program, perceived as successful until a relapse occurred post high school.
- The complexity of dealing with a patient who displayed denial, anger, and resistance during treatment.
- A multidisciplinary approach in a specialized program, involving various healthcare professionals.
- Family involvement in therapy and education; dynamics changed due to stress and fear of triggering Anna's eating behavior.

Anna's family emphasizes that anorexia is a disorder, not a choice, challenging societal stigma and urging for a better understanding of eating disorders.
They highlight the importance of education and open discussion surrounding mental health issues, particularly in the context of deadly consequences such as suicide.
