Another group of disorders which are of special interest to young people are eating disorders. These include anorexia nervosa, bulimia nervosa, and binge eating.

In bulimia nervosa, the individual may eat excessive amounts of food, then purge her/his body of food by using medicines such as laxatives or diuretics or by vomiting. The person often feels disgusted and ashamed when s/he binges and is relieved of tension and negative emotions after purging. In binge eating, there are frequent episodes of out-of-control eating. The individual tends to eat at a higher speed than normal and continues eating till s/he feels uncomfortably full. In fact, large amount of food may be eaten even when the individual is not feeling hungry.
