The parathyroid glands are four tiny glands located next to the thyroid gland in your neck. The glands release parathyroid hormone (PTH). Hypoparathyroidism is a condition in which not enough PTH is produced to keep levels of calcium, phosphorus, and vitamin D balanced in your body. The calcium levels in your blood and bones become too low, and the phosphorus levels get too high.
What are the causes?
This condition is caused by:
Removal of or injury to your parathyroid glands as a result of neck surgery.
DiGeorge syndrome, which can result in the underdevelopment or lack of parathyroid glands.
Autoimmune disease (your body begins to attack and destroy the parathyroid tissue).
High levels of cancer radiation treatment to your neck
