LEP and Obesity: These findings are consistent with previous studies showing a positive correlation between obesity and HbA1c levels in type 2 diabetes mellitus patients.[3–5] Similarly, research has reported elevated levels of total cholesterol and LDL in obese patients with type 2 diabetes mellitus.[4] The higher levels of leptin in the obese group in our study also agree with prior studies that have established a connection between obesity and increased leptin levels.
