Hypoparathyroidism

Definition of Hypoparathyroidism

Hypoparathyroidism is is an endocrine disorder in which the parathyroid glands in the neck do not produce enough parathyroid hormone (PTH).

Causes, incidence, and risk factors

The parathyroid glands help control calcium use and removal by the body. They do this by producing parathyroid hormone, or PTH. PTH helps control calcium, phosphorus, and vitamin D levels within the blood and bone.

Signs and tests

Blood tests will be done to check calcium, phosphorus, magnesium, and PTH levels. An may show abnormal heart rhythms.

Treatment

The goal of treatment is to restore the calcium and mineral balance in the body.

Expectations (prognosis)

The outcome is likely to be good if the diagnosis is made early. However, changes in the teeth, the development of cataracts, and brain calcifications are irreversible.
