Diabetic gustatory sweating

Abstract

Gustatory sweating is a potential manifestation of autonomic dysfunction in diabetes. This syndrome is seen in long-standing diabetes and is associated with nephropathy, peripheral neuropathy, and other signs of dysautonomia. Symptoms of profuse head and neck diaphoresis with eating may suggest this clinical diagnosis. We present a patient who had complicated diabetes with symptoms of gustatory sweating and other evidence of dysautonomia. Diagnosis and treatment possibilities are discussed, with a review of the literature and an emphasis on bedside testing.
