Osteoporosis and Type 2 diabetes mellitus are two common chronic conditions with potentially significant impacts on patients' health. Osteoporosis, characterized by decreased bone density and increased fracture risk, is influenced by various factors, including parathormone (PTH) and vitamin D levels. Aim: To study the association between PTH, vitamin D levels and BMD in Type 2 diabetic patients. Material And Methods:This cross-sectional observational study was conducted in the Department of Medicine. A total of 50 participants were included in the study. A semi-structured questionnaire was administered and relevant clinical data was obtained. Result: The results show a statistically significant association between vitamin D status and BMD (p = 0.008). Patients with normal vitamin D levels were more likely to have normal BMD, with 57.14% falling into this category. In contrast, 92.3% of patients with osteopenia and 75% of those with osteoporosis had low vitamin D levels. Conclusion: Low vitamin D levels were associated with a higher prevalence of osteoporosis and osteopenia, particularly in patients with low PTH levels.
