Results: The mean 25(OH) Vitamin D levels in Diabetic patients were 8.05 ±1.5 whereas the mean serum 25(OH) Vitamin D concentration in the control group was 34.28 ±13.42.Our study showed significantly lower levels of Vitamin D in Type 2 Diabetes Mellitus patients than in the control group. Also there was an inverse relation between HbA1c and Vitamin D levels which also emphasizes that those diabetics with Vitamin D deficiency had higher HbA1c levels.

Conclusion: Vitamin D appears to play a role in blood glucose regulation and low levels of Vitamin D may be a risk factor in development of Type 2 Diabetes Mellitus. There might be a beneficial effect in supplementation of Vitamin D to improve glycemic control in patients with Type 2 Diabetes Mellitus.
