[Diabetic neuropathy. II. Autonomic neuropathy. The gastrointestinal system]

Autonomic diabetic neuropathy of the alimentary canal takes several basic forms: a) oesophagopathy , b) gastroparesis, c) enteropathy, d) bile duct disorders. In many cases three are no subjective symptoms. In other the onset of the clinical condition may take acute and dangerous forms as in gastropathy. In still other cases e.g. enteropathy, the neuropathy may develop in bizarre and unexpected ways which are highly damaging to the patient's quality of life though in most cases they are not fatal. Bile disorders involving minimal motility after stimulus, as in denervation and reduced sensitivity to pain are particularly significant. Diabetics are more likely to suffer from calculosis (59.6% of cases), with septic complications (20% in diabetics compared to 7.8% in non-diabetics) or cholestasis (20% in diabetics v. 15.8% in non-diabetics). These figures indicate that all diabetics and especially the elderly should be subjected to careful examination to identify any bile disorders.
