Other Eating Disorders

Anorexia and bulimia nervosa and binge-eating disorder have strict diagnostic
criteria set forth by the American Psychiatric Association. However,
these three do not cover the entire spectrum of disordered eating patterns.
Those people who induce vomiting after consuming only a small amount of
food, for example, or those who chew large amounts of food and spit it out
rather than swallow it, do not fit the diagnosis of bulimia. For such persons, a
diagnosis of “Eating Disorder, Not Otherwise Specified” is used.
