My blood test report of 8 April shows 25 OH Vitamin D 17.3 ng/ml and serum calcium 10.3 mg/dl. It is usually said that vitamin D deficiency causes low calcium, but my calcium is almost high. Could there be another problem? I recently passed a kidney stone. Is it related? Is having sun exposure for 15 minutes every morning enough for vitamin D?

Low vitamin D with high calcium may point to other causes like hyperparathyroidism, especially with a history of stones. Sunlight helps, but supplements are often needed. Evaluate parathyroid hormone levels.
