The parathyroid glands are four pea-sized glands. They are located next to the thyroid gland in the neck. The glands secrete the parathyroid hormone (PTH). PTH helps to regulate the level of calcium in the blood.
In hypoparathyroidism, there is not enough PTH secreted. This causes low levels of calcium in the blood. Low blood calcium is known as hypocalcemia.
