The term "eating disorder" is very vague, suggesting simply a problem with food and with the act of eating. It suggests that there is only one "disorder," and by doing so, that there is only one cause.

One of the most valuable lessons that can be learned about eating disorders is that there are no perfect definitions, no definite causes, and no absolute cures.

Some of the common descriptions of Anorexia Nervosa, Bulimia, compulsive eating and compulsive exercising can be found below, as well as possible effects of these disorders, and ways to help people who suffer from them.

In presenting these descriptions, it must be emphasized that they are only lists of some possible characteristics of the problems. These lists are far from complete, and a person does not need to show all of the signs listed to have a problem. Any group of symptoms that disrupts an individual's lifestyle constitutes a problem.
