Anorexia Nervosa
Is a disorder characterized by the refusal of an emaciated individual to maintain a normal body weight. In addition, people with anorexia nervosa have a distorted evaluation of their own weight and body shape. They typically consider their emaciated bodies to be attractive or even a bit too fat, have a severely restricted and rigid diet, and have an intense fear of gaining weight. In women the weight loss is accompanied by amenorrhea (failure to menstruate for at least three consecutive months). An estimated 5–20 percent of people with the disorder die as the result of starvation or medical complications that are caused by low weight and a restricted diet.
Bulimia
Is characterized by binge eating followed by compensatory behavior such as self-induced vomiting, fasting, or excessive exercise.
