Bulimia - Overview

Alternative Names

Bulimia nervosa; Binge-purge behavior; Eating disorder - bulimia

Definition of Bulimia:

Bulimia is an illness in which a person binges on food or has regular episodes of overeating and feels a loss of control. The affected person then uses various methods -- such as vomiting or laxative abuse -- to prevent weight gain.

Many (but not all) people with bulimia also have anorexia nervosa.

Causes, incidence, and risk factors:

Many more women than men have bulimia. The disorder is most common in adolescent girls and young women. The affected person is usually aware that her eating pattern is abnormal and may feel fear or guilt with the binge-purge episodes.

The exact cause of bulimia is unknown. Genetic, psychological, trauma, family, society, or cultural factors may play a role. Bulimia is likely due to more than one factor.
