Eating disorders refer to a group of conditions defined by abnormal eating habits that may involve either insufficient or excessive food intake to the detriment of an individual's physical and mental health. Bulimia nervosa, anorexia nervosa, and binge eating disorder are the most common specific forms in the United States.[1] Though primarily thought of as affecting females (an estimated 5–10 million being affected in the U.S.), eating disorders affect males as well (an estimated 1 million U.S. males being affected).[2][3][4] Although eating disorders are increasing all over the world among both men and women, there is evidence to suggest that it is women in the Western world who are at the highest risk of developing them and the degree of westernization increases the risk.
