[Eating disorders in obese individuals--a psychiatric or internal medicine issue?].

Many relations are connecting obesity and eating disorders--one disease is often modifying the other. Anorexia Nervosa and Bulimia Nervosa are mostly treated by psychiatrists. Internal medicine specialists are mostly involved only in complications (e.g. malnutrition, ion disorders). Obesity is mostly treated only by internists. Psychiatrists are only involved in some depressive patients. Obese patients with eating disorders are mostly not sent to psychiatric diagnostics. In this article an overview of eating disorder symptoms and classification is given--binge eating disorder, night eating syndrome and grazing. These symptoms are defined and possibilities of diagnosis and treatment are described.
