Hypercalcemia in a Weight Lifter on Nutritional Supplements

ABSTRACT

Hypercalcemia commonly occurs secondary to hyperparathyroidism or malignancy. We describe a case of a young weightlifter who had been consuming over the counter multivitamin pills containing vitamin A and D and was detected to have hypercalcemia, metastatic calcification and renal insufficiency. The relevant literature on vitamin A and D intoxication and hypercalcemia is reviewed.
