[Disorders of gastrointestinal motility--diabetes mellitus].

Diabetic motility disturbances are frequent and may be found within esophagus, stomach, small bowel, colon and anal sphincter. Disturbed motility may explain gastrointestinal symptoms of patients with diabetic enteropathy, but there is no correlation between symptoms and extent of motility changes. Prokinetic drugs relief symptoms, but also without improving motility parameters. Diarrhea is best treated by local opoid agonists (loperamide), in anorectal incontinence biofeedback training is also to be recommended.
