disordered eating

Disordered Eating is a term that is used by some people to describe a wide variety of irregularities in eating behavior that do not warrant a diagnosis of a specific eating disorder such as anorexia nervosa or bulimia nervosa. People who have this kind of disordered eating patterns may be diagnosed with an eating disorder not otherwise specified. A change in eating patterns can also be caused by other mental disorders (e.g. clinical depression), or by factors that are generally considered to be unrelated to mental disorders (e.g. extreme home-sickness).
