Objective: The number of patients with hypercalcemia due to different causes has been ever increasing in our settings, mostly because of both prescribed as well as over the counter supplements. In o rder to see the trends of such patients and to understand the most common etiology, the present study was conducted in this hospital over a period of 16 months. Methods: Over a period of 16 months, all such patients who were admitted in this hospital with symptomatic hypercalcemia due to different causes were studied and their data was collected and interpreted. Besides serum calcium levels, the serum levels of PTH and 1, 25 dihydroxy Vitamin D were measured. Results: In this study of 16 months duration, a total of 24 patients were admitted with hypercalcemia, out of whom 13 patients had Vitamin D intoxication (54%) as the cause, 9 patients had malignancy, 3 patients were having primary hyperparathyroidism and 2 patients had hypercalcemia of undiagnosed cause. Conclusion: Hypercalcemia due to vitamin D intoxication (a treatable cause) is becoming the leading cause of hypercalcemia in this setting of a tertiary care centre.
