Causes
By Mayo Clinic staffThe exact cause of bulimia is unknown. As with other mental illnesses, there are many possible factors that could play a role in the development of eating disorders, such as genes, certain behaviors, psychological disorders, and family and societal influences:
- Biology. There may be genes that make some people more vulnerable to developing eating disorders. People with first-degree relatives — siblings or parents — with an eating disorder may be more likely to develop an eating disorder too, suggesting a possible genetic link. It's also possible that a deficiency in the brain chemical serotonin may play a role in the development of bulimia.
- Behavior. Certain behaviors, such as dieting or overexercising, can contribute to the development of bulimia. For example, dieting is a primary factor in triggering binge eating. In addition, dieting helps encourage rigid rules about food, which when broken can lead to loss of control and overeating.
- Emotional health. People with eating disorders may have psychological and emotional problems that contribute to the disorder. They may have low self-esteem, perfectionism, impulsive behavior, anger management difficulties, family conflicts and troubled relationships, for instance.
- Society. The modern Western cultural environment often cultivates and reinforces a desire for thinness. Success and worth are often equated with being thin in popular culture. Peer pressure and what people see in the media may fuel this desire to be thin, particularly among young women.
