Causes
By Mayo Clinic staffIt's not known specifically what causes binge-eating disorder. As with many mental illnesses, it's thought that a variety of factors are at play in binge-eating disorder and may include:
- Biological. Biological vulnerability may play a role in developing binge-eating disorder. Both genes and brain chemicals may be involved. In addition, researchers are studying appetite regulation of the central nervous system for clues, along with gastrointestinal changes that might shed light on causes.
- Psychological. Psychological and emotional characteristics may also contribute to the condition. You may have low self-worth and trouble controlling impulsive behaviors, managing moods or expressing anger.
- Sociocultural. Modern Western culture often cultivates and reinforces a desire for thinness. Although most people who have binge-eating disorder are overweight, they're acutely aware of their body shape and appearance and berate themselves after eating binges. Some people with binge-eating disorder have a history of being sexually abused.
