Bulimia
Bulimia, an eating disorder in which persistent overconcern with body weight and shape leads to repeated episodes of binging (consuming large amounts of food in a short time) associated with induced vomiting, use of laxatives, fasting, and/or excessive exercise to control weight. Sometimes bulimic behavior is observed in cases of anorexia nervosa , or abnormal dieting, but bulimia in itself does not result in severe weight loss. It can, however, cause gastrointestinal problems and serious potassium depletion, and teeth may be damaged due to the acid nature of the regurgitated food. Bulimia usually develops during adolescence (most commonly among females) as a result of various psychological pressures, the most obvious one being the social emphasis on the desirability of slimness. Various modes of group and behavioral therapy are used in treating the disorder. Because patients with bulimia often suffer from depression as well, antidepressant drugs may be effective
