Bulimia nervosa is defined as uncontrolled episodes of overeating (bingeing) usually followed by self-induced vomiting, misuse of laxatives, enemas, or medications in an attempt to control weight.
Anorexia nervosa is an eating disorder that is a form of self-starvation. A child or teen with anorexia has abnormally low body weight, a distorted body image, and an intense fear of gaining weight.
At least 8 million people in the U.S. are living with an eating disorder. The overwhelming majority—about 90%—are female.
