Article: Eating disorder

An eating disorder is a compulsion to eat in a way which disturbs physical health. The eating may be excessive (compulsive over-eating); too limited (restricting); may include normal eating punctuated with episodes of purging; may include cycles of binging and purging; or may encompass the ingesting of non-foods. The best-known eating disorders are Anorexia nervosa and Bulimia nervosa. There are numerous theories as to the causes and mechanisms leading to eating disorders. The two most common eating disorders are anorexia and bulimia. Both of these have severe consequences to a person's health and can even cause death.

Eating disorders are characterized by an abnormal obsession with food and weight. Eating disorders are much more common in women than in men, particularly teenaged girls, where eating disorders are on the rise. Over 50% of the people with an eating disorder also have a comorbid diagnosis of severe mental depression.^{[citation needed]} The American Psychiatric Association lists eating disorders. Some psychologists also classify a syndrome called orthorexia as an eating disorder, or, more properly, "disordered eating" - the person is overly obsessed with the consumption of what they see as the 'right' foods for them, to the point that their nutrition and quality of life suffers (although due to cultural and political factors which influence food choices, this idea is considered controversial by some). In addition, some individuals have food phobias about what they can and cannot eat, which can be characterised as an eating disorder. Somewhat qualitatively different from those conditions previously mentioned is pica, or the habitual ingestion of inedibles, such as dirt, wood, hair, etc. This is a condition particularly prevalent in children.
