Binge Eating is quite similar to bulimia, however, it differs from bulimia because its sufferers do not purge their bodies of excess food. They will eat large quantities of food, and do not stop until they are uncomfortably full. Most people with binge eating disorder are obese and have a history of weight fluctuation. Recent research shows that binge eating disorder occurs in about 30 percent of people participating in medically supervised weight control programs.Although Binge Eating does not attract the kind of attention that Anorexia and Bulimia do, it is still apparent that those who binge can cause tremendous amount of damage to their bodies. Furthermore binge eating is a reflection of a deeper imbalance within the sufferer, which may be indicative of a basic breakdown of body and food relationship that if not dealt with can develop from binge eating to other more deadly eating disorders.
Binge eaters do not necessarily throw up afterwards, however that may be an unintended consequence of eating a huge quantity. Bulimic's actually do try and make themselves throw up, and may do so after a normal sized meal rather than just after a period of binge eating.
Bulimic behavior exists from two distinct phases, the binge and the purge. This behavior is typical for individuals with severe self image problems and needs to treated by professionals as it is a potential life threatening psychological disorder.
