The Saxon Study for General Medicine (SESAM) investigated the reasons why patients consulted the general physician, what diagnoses were established, and how the patients were subsequently treated. In the majority of cases, the reason for the abdominal complaints was located in the gastrointestinal or urogenital tract, in the presence of infections or psychosomatic problems. Gynecological problems must also be considered, while diseases other than gastrointestinal are of no significance for the differential diagnosis of abdominal complaints in the general physician's office.
