*[[Anorexia Nervosa]] (AN), characterized by refusal to maintain a healthy body weight, an obsessive fear of gaining weight, and an unrealistic perception of current body weight. However, some patients can suffer from Anorexia nervosa unconsciously. These patients are classified under "atypical eating disorders". Anorexia can cause menstruation to stop, and often leads to bone loss, loss of skin integrity, etc. It greatly stresses the heart, increasing the risk of heart attacks and related heart problems. The risk of death is greatly increased in individuals with this disease.
*[[Bulimia nervosa Nervosa]] (BN), characterized by recurrent binge eating followed by compensatory behaviors such as purging (self-induced vomiting, excessive use of laxatives/diuretics, or excessive exercise). Fasting and over exercise may also used as a method of purging following a binge.
*Binge eating disorder (BED) or 'compulsive overeating', characterized by binge eating, without compensatory behavior. This type of eating disorder is even more common than Bulimia or anorexia. This disorder does not have a category of people in which it can develop. In fact, this disorder can develop in a range of ages and is unbiased to classes.
*Compulsive overeating, (COE) characteristic of binge eating disorder, in which people tend to eat more than necessary resulting in more stress. This is mainly caused by 'binge eating disorder'.
