Eating disorders develop for a variety of reasons. That is, while many individuals with eating disorders think and act in very similar ways, the reasons they have these thoughts and actions can be quite different. Although many people view these behaviors as self-destructive acts, most individuals who develop eating disorders do not usually perceive their behaviors as self-harmful. Actually, most patients feel that they began the behaviors to try to fix other problems. The most common reason therapists hear from people about why they began self-starvation, bingeing or purging is that at some point they felt terribly out of control — whether because of something they were feeling inside themselves or something that was happening to them from their outside environment.
