Hypoparathyroidism: Condition Information

What is hypoparathyroidism?

Hypoparathyroidism is a condition in which the body doesn’t make enough parathyroid hormone (PTH).¹

Parathyroid glands are small endocrine glands that are located in the neck behind the thyroid gland. These glands secrete PTH in response to decreasing calcium in the circulation. This hormone regulates the amount of calcium, magnesium, and phosphorus in your body. Decreased levels of PTH lead to low levels of calcium and magnesium and high levels of phosphorus in the blood. This imbalance can lead to problems with bones, muscles, skin, and nerve endings.
