[Eating disorders and diabetes mellitus].

Numerous empirical studies indicate a higher frequency of eating disorders such as anorexia or bulimia nervosa in young female diabetic patients compared to the normal population. The comorbidity of the two syndromes usually leads to a continuous metabolic disorder bearing high risks of acute metabolic failure or early microangiopathic lesions. In addition to "restraint eating" as an essential element of diabetic therapy a premorbid neurotic malformation and/or poor coping strategies are further predisposing aspects for the development of an eating disorder. The inpatient treatment of a 22 year old patient suffering from both diabetes mellitus and bulimia nervosa demonstrates the association of neurotic malformation, poor coping style and the directive function of diabetic therapy.
