Bulimia nervosa, also called bulimia, is a psychological eating disorder that is characterized by episodes of binge eating (consuming a large quantity of food in one sitting) followed by inappropriate methods of weight control, such as vomiting, fasting, enemas, excessive use of laxatives and diuretics, or compulsive exercising.
Bulimia tends to develop late in childhood or in early adulthood. It affects females more often than males. People with bulimia often perform the behaviors in secret, feeling disgusted and ashamed when they binge, yet relieved once they purge. People with bulimia usually weigh within the normal range for their age and height. However, they may fear gaining weight, have desire to lose weight, and may feel intensely dissatisfied with their bodies.
What Causes Bulimia Nervosa?
The exact cause of bulimia is not known, but research suggests that a combination of certain personality traits, emotions, and thinking patterns, as well as biological and environmental factors might be responsible. Researchers also believe that this eating disorder may begin with a dissatisfaction of the person's body and extreme concern with body size and shape. Usually individuals suffering from bulimia have low self-esteem and fear becoming overweight. The fact that bulimia tends to run in families also suggests that a susceptibility to the disorder might be inherited.

How Is Bulimia Treated?
Bulimia treatment requires the consideration of the physical as well as the psychological needs of the person. Treatment may include psychological counseling and medications such as antidepressants or other drugs. In many cases, treatment is undertaken by a team of medical, nutritional, and mental health professionals. The ideal outcome of treatment is to restore physical health and normal eating patterns.
What Is the Outlook for People With Bulimia?
Bulimia is a condition that is difficult to cure. Many people improve, but relapses may recur from time to time in some cases. In addition, some people who are considered "cured" continue with less-than-normal eating patterns throughout their lives. In general, however, the outlook for people with bulimia is more positive than the outlook for people with anorexia, another eating disorder.
