Steatorrhea Complicating Diabetes Mellitus with Neuropathy: Report of Cases without Apparent External Pancreatic Insufficiency

Disturbances of gastrointestinal function have frequently been observed in association with diabetes mellitus. The disorders which have been reported include gastric atony and dilatation, postprandial abdominal cramping, severe constipation, and intractable diarrhea characterized by watery stools, nocturnal exacerbations and fecal incontinence. These disturbances have been attributed by many investigators to alterations in gastrointestinal motility secondary to visceral diabetic neuropathy. The purpose of the present report is to call attention to a group of patients with diabetes mellitus and neuropathy who exhibited diarrhea and steatorrhea which apparently could not be attributed to external pancreatic insufficiency.
