THREE major eating disorders within the general population:

Bulimia Nervosa

Bulimia Nervosa is characterized by continual episodes of binge eating followed by purging.
A binge involves eating large amounts of food in a discrete period of time. After a binge, vomiting is induced and/or laxatives are used. In these cases involve excessive exercise as a form of purging. Body weight is often normal in these cases. A secretive eating pattern is also seen in them. Usually nervous or agitated behavior is seen immediately after eating. There is either loss or gain of extreme amounts of weight.
