Introduction: Diabetes mellitus (DM) is a result of heterogeneous metabolic disorders, causes hyperglycemia due to deficiency in secretion and/or insulin action. The present retrospective cross-sectional study was done among 78 T2DM patients. Serum 25-hydroxyvitamin D [25(OH)D] levels reflect body stores of vitamin D which was measured in all and classified as normal (≥30ng/mL), insufficient (>20 to 29.9ng/mL), and deficient (≤20ng/mL). The mean serum 25(OH) D level was 27.91±2.58ng/mL (mean±SD). Aim of the Study: Aim of the study was to find out the vitamin D status in type 2 diabetes mellitus patients. Methods: This retrospective cross-sectional study was conducted in SMC Niltara Clinic, Dhaka, Bangladesh during the period from January 2020 to December 2020. All the results were statistically analysed by were taken by SPSS-20 version and MS-Excel-16. Result: In total 78 patients divide into two groups. In Vitamin-D status was 24(41.38%) found normal in male and 8(40.00%) in female; insufficient found 22(37.93%) in male and 11(55.00%) in female; deficient found 12(20.69%) in male and 1(5.00%) in female. There was no statistical difference of 25(OH)D level between males and females (26.79±2.1 vs. 31.09±8.2ng/mL, mean±SEM; p=0.470); among smokers, non-smokers and ex-smokers (26.86±4.31, 27.10±2.49 and 42.62±1.71ng/mL respectively, mean±SEM; p=0.363); among normal weight, overweight and obese (30.61±6.16, 35.61±9.52 and 24.27±1.71ng/mL respectively, mean±SEM; p=0.191); and among normotensive, borderline hypertensive and hypertensive (25.29±2.46, 32.57±5.32 and 20.84±3.66ng/mL respectively, mean±SEM; p=0.277) patients. 25(OH) D level showed significant negative correlation with body mass index (r= -0.391, p=0.017) and positive correlation (r=0.334, p=0.044) with fasting plasma glucose in male subjects. Conclusion: A large portion of Type-2 diabetes mellitus (DM) subjects in Bangladesh has subnormal vitamin D as revealed by our study. Vitamin D level had a significant..
