People with anorexia have a real fear of weight gain and a distorted view of their body size and shape. As a result, they can't maintain a normal body weight. Many teens with anorexia restrict their food intake by dieting, fasting, or excessive exercise. They hardly eat at all — and the small amount of food they do eat becomes an obsession.
Others with anorexia may start binge eating and purging — eating a lot of food and then trying to get rid of the calories by forcing themselves to vomit, using laxatives, or exercising excessively, or some combination of these.
