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 the way your heart and brain works. Hypercalcemia most commonly results from overactive parathyroid glands. These four tiny glands are each about the size of a grain of rice and are located on or near the thyroid gland.
A more technical description is given below: Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands.he second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed (reabsorbed) into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.
