Background: Vitamin D is essential for bone and muscle health. Deficiency is common worldwide and often asymptomatic. This study evaluates the prevalence of Vitamin D deficiency and the proportion of symptomatic cases in patients undergoing routine health check-ups.

Methods: A retrospective analysis of 646 patients attending routine check-ups over six months was conducted. Serum vitamin D levels were measured. Patients with Vitamin D <20 ng/ml were classified as deficient. Symptomatic cases were identified based on musculoskeletal complaints.

Results: Among 646 patients undergoing routine check-ups (146 males, 500 females; age 19- 87 years), 313 (48.5%) had vitamin D deficiency. Of these, 85 (27.2%) were symptomatic. Overall, symptomatic vitamin D deficiency was present in 13.2% of all patients.

Conclusion: Vitamin D deficiency is prevalent in the study population undergoing routine health evaluation. A substantial proportion is asymptomatic, highlighting the importance of screening and preventive strategies.
