Nonalcoholic fatty liver disease (NAFLD) is frequently associated with type 2 diabetes mellitus, obesity, and dyslipidemia. We tested the hypothesis that there may be an association between NAFLD and insulin resistance (IR); and its correlation with glucose tolerance status of subjects who aren't known patients with diabetes. One hundred and seventy-six consecutive patients with elevated serum aminotransferase levels and bright liver were evaluated. Sixty-two patients were excluded from the study. Age, gender, height, weight, body mass index, waist circumferences, and family history of diabetes were recorded. Fasting plasma glucose, insulin, lipid profile were measured. A standard oral glucose tolerance test (OGTT) was performed and the index of IR was calculated according to the HOMA method. Patients with a normal glucose tolerance formed group 1 (64 patients) and patients with impaired or diabetic glucose tolerance group 2 (50 patients). Age, female sex, family history of type 2 diabetes, fasting insulin, fasting plasma glucose and HOMA-R index were statistically significantly different between the groups. Although the subjects in the study are not known patients with diabetes, the prevalence of impaired or diabetic glucose tolerance was prominent. In conclusion, performing OGTT in cases with nonalcoholic fatty liver disease may be useful for early screening of diabetes mellitus.
