Overview

Anorexia nervosa and bulimia nervosa are both serious eating disorders, but they differ in behaviors and physical effects. Anorexia involves extreme restriction of food intake, intense fear of gaining weight, and significant weight loss. Bulimia is marked by cycles of binge eating followed by purging behaviors such as vomiting or excessive exercise. While anorexia often leads to being underweight, individuals with bulimia may have a normal weight or be overweight. Both conditions have serious psychological and physical consequences and require professional treatment.

Disease Summaries

Anorexia: Anorexia nervosa is an eating disorder marked by intense fear of gaining weight, distorted body image, and self-imposed starvation leading to significantly low body weight. It can affect physical health (including heart, bone, and hormonal health) and mental wellbeing. The exact cause is multifactorial, including genetic, psychological, and environmental factors.

Bulimia: Bulimia nervosa is characterized by recurring episodes of binge eating followed by compensatory behaviors such as self-induced vomiting, fasting, or excessive exercise. Individuals often have a normal or near-normal weight but experience shame, guilt, and secrecy around eating behaviors.

Treatment Approaches

Anorexia Treatment Approaches

Treatment requires a multidisciplinary approach. Nutritional rehabilitation is the first priority, often combined with individual or family-based therapy. Cognitive behavioral therapy (CBT) is commonly used. In some cases, hospitalization may be needed to address severe malnutrition or medical instability. Ongoing psychological support is essential for long-term recovery.

Bulimia Treatment Approaches

The mainstay of treatment is psychotherapy, especially cognitive behavioral therapy. Nutritional counseling helps normalize eating patterns. Medications may help reduce binge-purge cycles. Support groups and education play a key role. Inpatient treatment may be required for severe cases or when complications arise.
