Plasma insulin response to oral glucose load in Menière's disease.

Oral glucose tolerance tests and plasma insulin measurements were carried out in 74 patients with Menière's disease and 74 control subjects. No statistically significant differences were observed in fasting, one-hour, and two-hour blood glucose levels or in fasting, one-hour, and two-hour plasma insulin levels between patients with Menière's disease and control subjects. The results do not confirm the hypothesis that disturbances in glucose metabolism or plasma insulin response are etiologic factors in Menière's disease.
