Aim: To determine the incidence of vitamin-D deficiency in patients presented to us with complains of aches and pain in body. Methods: This prospective study was carried out in Dr. Wasima Talat Clinic, Mall Road, Multan from January 2014to May 2014. A total of 120 patients were included in the study. Results: Out of 120 patients, 80 (66.7%) were female and 40 (33.3%) male. 56 (70%) out of 80 female patients had vitamin-D deficiency (<20 ng/mL) and 14 (17.5%) out of 80 patients had vitamin-D insufficiency (21-29 ng/mL). 25 (62.5%) out of 40 male patients had vitamin-D deficiency (<20 ng/mL) and 8 (20%) out of 40 male patients had vitamin-D insufficiency (21-29 ng/mL). So, out of 120 patients 81 (67.5%) had vitamin-D deficiency (<20 ng/mL) and 22 (18.3%) patients had vitamin-D insufficiency (21-29 ng/mL). Total 103 (85.8%) out of 120 patients were suffering from vitamin-D deficiency/insufficiency (<30 ng/mL). 17 (14.13%) out of 120 patients had sufficient levels of vitamin D (>30 ng/mL). Conclusion: Prevalence of Vitamin D deficiency is alarmingly high in patients presenting with fatigue, even more than that seen in other parts of the world.
