An unusual case of gustatory sweating.

Facial sweating after food (gustatory sweating) is a recognized complication of long-standing insulindependent diabetes mellitus (Watkins, 1973). It is usually provoked by cheese, salty or spicy foods and accompanies other features of autonomic and peripheral neuropathy. The patient herewith reported is unusual in that he developed gustatory sweating as a major, but relatively isolated complication, whilst on treatment with oral hypoglycaemic agents, albeit during a period of deteriorating diabetic control.
