[Anorexia nervosa in a young diabetic].

Coexistence of diabetes mellitus and anorexia nervosa has been noted in the past 2 decades. The nature and treatment of diabetes offer numerous opportunities for the anorectic patient to lose weight. Improper adjustment of the insulin dose, failure to inject insulin, clandestine vomiting and failure to provide urine samples allow the anorectic diabetic to achieve morbid weight loss. The treatment of patients with both conditions is difficult; behavioral management combined with psychotherapy was found to be most effective. An illustrative case is presented.
