[Changes in gastrointestinal motility in the diabetic].

The frequency and pathophysiology of disorders of gastro-intestinal motility associated with diabetes are poorly understood. Gastroparesis is often misdiagnosed, although it can be responsible for diabetic instability. Constipation is the most frequent gastro-intestinal symptom, although the patient may present alternating episodes of diarrhoea and constipation. The pathophysiology of these disorders is still poorly understood. It could well be caused by diabetic neuropathy.
