Main Causes of Bulimia

See Your Abs Review Some people may feel that they are fat, no matter how thin they actually are. Or they may feel guilty when they eat too much food. The guilt and shame from eating makes the person vomit up all their food. These people have bulimia nervosa, or bulimia, an eating disorder. The disorder has nothing to do with the digestive system, but rather with the mind. And though people with bulimia may share the same guilt and shame about food, and the same patterns of bingeing and purging, bulimia has many causes. Doctors have not identified any one cause of bulimia, but do know of several factors that may contribute to developing bulimia.

Bulimia may be caused by a genetic component. Certain genes may predispose a person to developing bulimia. Bulimia appears to run in families--people with relatives suffering from bulimia have a higher frequency of developing bulimia. This may, however, have more to do with family influences and role models than genetics.Brain chemistry may also cause bulimia. Research indicates that people with bulimia tend to have different levels of a chemical in the brain called serotonin. Altered levels of serotonin may also contribute to clinical depression.
