Causes Of Hypocalcemia To Watch For
Hypoparathyroidism

Hypoparathyroidism is a deficiency in parathyroid hormone (PTH). This hormone, secreted by the parathyroid gland in the throat, regulates calcium and phosphorus in the blood as kidneys do. Without the parathyroid gland and the regular thyroid, the body cannot metabolize food and liquids properly.
It's rare to have this disorder, but it is possible. Some of the contributing factors are magnesium deficiency, an incorrectly-performed thyroid surgery, or congenital genetic disorders. It can also be caused by trauma to the neck, which can damage the blood vessels. The only ways to treat this disorder and counteract hypocalcemia are calcium carbonate tablets, intravenous vitamin D, or synthetic PTH.
Intolerance To Foods High In Calcium

Another factor that can cause hypocalcemia is an intolerance to foods high in calcium. Many individuals confuse this for lactose intolerance, but it isn't the same thing. The main factor in this symptom is an inability of the body to break down the calcium in certain foods, leading to its elimination through urine or feces. The cause of this intolerance is unknown, but many believe genetics is connected. The only way to counteract this intolerance is to monitor intake carefully, and have urine checked regularly to ascertain calcium levels. The patient may receive calcium supplements, which are easier to absorb.
