Hypoparathyroidism is a rare condition in which your body secretes abnormally low levels of parathyroid hormone (parathormone). This hormone plays a key role in regulating and maintaining a balance of your body's levels of two minerals — calcium and phosphorus.

The low production of parathyroid hormone in hypoparathyroidism leads to abnormally low ionized calcium levels in your blood and bones and to an increased amount of phosphorus.

Treatment for hypoparathyroidism consists of taking supplements to normalize your levels of calcium and phosphorus. Because hypoparathyroidism is a chronic condition, treatment is generally lifelong.
