When the blood calcium level is too low, PTH is released to bring the calcium level back up to normal. When the calcium level is normal or gets a little too high, normal parathyroids will stop releasing PTH. Proper calcium balance is crucial to the normal functioning of the heart, nervous system, kidneys, and bones. In bone, vitamin D may play a synergistic role with parathyroid hormone (PTH) in stimulating osteoclast proliferation and bone resorption.

Likewise, too high a calcium level parathyroid hormone function cause a person to feel run down, cause them to sleep poorly, make them more irritable than usual, and even cause a decrease in memory. Even though half of patients with this hyperparathyroidism Parathyroid Disease will state that they feel just fine, after a successful parathyroid operation more than 85 percent of these patients will claim parathyroid hormone function "feel much better"!

Parathyroid Hormone

Phosphate ions form water-insoluble salts with calcium. Thus, a decrease in the phosphate concentration of the parathyroid hormone function plasma for a given total calcium concentration increases the amount of calcium that is ionized.


This latter form of vitamin D is the active hormone which stimulates calcium uptake from the intestine. Further information on the symptoms parathyroid hormone function each condition can be found in the individual articles.

It can result in low levels of calcium parathyroid hormone function the blood hypocalcaemia.

Function of the parathyroid glands

But calcium has other functions. It aids in the transmission of signals in nerve cells, and it's involved in muscle contraction.

Phosphorus, another mineral, works in conjunction with calcium in these areas. The disorder can generally be divided into two types based on the cause.

Hyperparathyroidism may occur because of a problem with the parathyroid glands themselves primary hyperparathyroidism or because of another disease that affects the glands' function secondary hyperparathyroidism.

Primary hyperparathyroidism Primary parathyroid hormone function occurs because of some problem with one or more of the four parathyroid glands: A noncancerous growth adenoma on a gland is the most common cause.

Enlargement hyperplasia of two or more parathyroid glands accounts for most other cases.
