A COMPARISON OF THE METABOLIC PARAMETERS OF OBESE AND NON-OBESE NAFLD PATIENTS WITH INSULIN RESISTANCE INTRODUCTION-AIM: It is frequently comorbid with obesity and insulin resistance. However, NAFLD is also seen in non-obese individuals. The purpose of this study was to compare insulin resistance and metabolic parameters in obese and non-obese NAFLD patients. MATERIALS-METHOD: 50 obese (BMI >=30) and 50 non-obese (BMI 2.5. RESULTS: Fifty were obese and 50 were non-obese. Insulin resistance was determined in 60% of obese patients and 50% of non-obese patients (in 55% of the entire group). The difference was not significant (p:0.3). Conclusion: We compared metabolic parameters of obese and non-obese patients with NAFLD and insulin resistance. We observed significant differences between insulin levels, HOMA-IR, GGT and indirect bilirubin levels in subjects with insulin resistance. In conclusion, we think that fatty liver disease is by itself a risk factor for insulin resistance independent of obesity, and that GGT and indirect bilirubin levels in particular can show insulin resistance in patients with hepatic steatosis.
