Overview

Hypercalcemia is a condition in which the calcium level in your blood is above normal. Too much calcium in your blood can weaken your bones, create kidney stones, and interfere with how your heart and brain work.

Hypercalcemia is usually a result of overactive parathyroid glands. These four tiny glands are situated behind the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and taking too much of calcium and vitamin D supplements.

Signs and symptoms of hypercalcemia range from nonexistent to severe. Treatment depends on the cause.
