Hypoparathyroidism

What is Hypoparathyroidism?

Hypoparathyroidism meaning Caused by underactive parathyroid glands. Parathyroid glands are four small glands located next to the thyroid. They are responsible for regulating blood calcium levels as well as magnesium and phosphorus levels. If the parathyroid glands do not produce or secrete enough parathyroid hormone (PTH), it will result in low levels of calcium in the bloodstream. The low levels of calcium lead to muscle spasms, or tetany, an increased excitability of the nerves, and disturbances in heart rhythm.The most common cause of hypoparathyroidism is injury to or accidental removal of all four glands during a removal of the thyroid. Some people are born without parathyroid glands or the glands function suddenly decline due to unknown reasons.
