In recent years, a number of studies have been carried out, the results of which suggest that the exocrine function of the pancreas is significantly more frequently impaired than is the case in healthy controls. In particular when a patient presents with gastrointestinal complaints of unclear origin, unexplained fluctuations in blood sugar, or loss of weight, the possibility of pancreatic exocrine insufficiencyshould be included in differential diagnostic considerations. Abnormal stools and intolerance of dietary fat can be clarified on the basis of a careful history. The diagnosis is confirmed with the aid of simple laboratory tests, for example the chemotrypsin test or the detection of elastase 1 in the stools. By way of treatment, pancreatic enzyme replacement can be applied.
