Esophageal disorders in diabetes mellitus.

Esophageal motility disturbances are common in diabetics in general and are most prevalent in these with peripheral neuropathy or autonomic neuropathy. The usual findings are a decrease in the amplitude of esophageal contractions in the smooth muscle portion of the body, frequent absence of primary peristalsis, simultaneous or repetitive body contractions, and a decrease in the velocity of peristalsis. Radiographically, this may be manifest as delayed esophageal emptying. These changes do not produce symptoms. Dysphagia and chest pain should be thoroughly evaluated and not ascribed to the diabetes. Candidiasis may be more common in diabetics.
