Objectives: We investigated the incidence of hyperinsulinemia
in patients presenting with tinnitus and
evaluated the effect of diabetic diet on tinnitus.
Pat ients and Methods: Serum insulin levels were measured
and oral glucose tolerance test was performed in
52 patients (26 males, 26 females; mean age 50 years;
range 20 to 80 years) with idiopathic tinnitus. Those with
hyperinsulinemia were given a diabetic diet for four
months. A questionnaire was administered to all the
patients and the complaint of tinnitus was assessed
according to a rating scale before and after treatment.
The results were compared with those of 15 age-and
Results: Hyperinsulinemia was detected in 76%
and 27% of the patients and the controls, respectively
(p<0.05). Oral glucose tolerance test was normal
in 48% of the patients, and in 80% of the controls
(p<0.05). Following a diabetic diet, the severity
of tinnitus complaints significantly decreased in
patients with hyperinsulinemia (p<0.0001).
Conclusion: Hyperinsulinemia may play an etiologic
role in tinnitus and a diabetic diet may result in significant
improvement in tinnitus complaints in this population.
