[Hyperinsulinemia in vertigo, tinnitus and hearing loss].

48 patients (25 woman, mean age 42 +/- 9.9 years and 23 men, mean age 46.6 +/- 8.3 years) suffering from vertigo, tinnitus and hearing loss of unknown origin were included into this study. The occurrence and coexistence of symptoms was measured. Insulin levels were measured fasting and at the second hour of OGTT. Results were compared with the control group of 31 healthy persons (16 women, mean age 41.3 +/- 5.6 years and 15 men, mean age 47.6 +/- 9.4 years). The character of vertigo, localization of hearing loss and electronystagmographic findings showed the pathology of the inner ear. The occurrence of hyperinsulinemia was significantly more common in the patients group--43.8%, comparing to the control group--22.6%. Also the insulin levels in the second hour of OGTT, were statistically significantly higher in patients that in the control group.
