Summary

Typical clinical symptoms of diabetes mellitus have been described as early as 1500 bc in the Ebers Papyrus. When sufficient indirect tests of exocrine pancreatic function became available, it enabled researchers to study larger groups of patients. In the first single-center study in 30 patients with T1D and 83 patients with T2D, exocrine insufficiency was demonstrated in 56.7% and 35%, respectively, as compared to 18.1% in controls. It can be concluded that the finding of pancreatic exocrine insufficiency in diabetic patients is much more common than in age-matched controls and that fecal fat digestion is also altered in these patient. There are some autopsy studies reporting morphological changes of the exocrine pancreas in patients with diabetes mellitus. The possible coexistence of exocrine pancreatic disease and diabetes mellitus has relevant implications for the clinical treatment of affected patients.
