Your guide to the Thyroid.

Parathyroid Hormone

Parathyroid hormones are considered to be the most important endocrine regulator. It basically regulates the calcium and phosphorus concentration in the body. These hormones are secreted from the cells of the parathyroid gland. The parathyroid gland is the small endocrine glands found in an individual’s neck just behind the thyroid gland. Parathyroid hormones also have major effects on development. The body needs just enough parathyroid hormones. If one’s parathyroid glands do not produce or secrete enough parathyroid hormones, this may cause one’s calcium level to drop. If one’s calcium level in the body drops, one may suffer from hypothyroidism. Hypothyroidism happens when the thyroid glands fail to produce enough thyroid hormones. One’s parathyroid hormone level can be checked through a parathyroid hormone test. The parathyroid hormone test is done to identify if an individual is suffering from hypothyroidism. Parathyroid hormone tests may also help in finding the cause why an individual’s calcium level is abnormal. It may also help physicians to check if the parathyroid glands are the ones causing the abnormal calcium level. It may be considered as well to determine if an individual has chronic kidney problems.

Parathyroid Hormone Levels

One’s parathyroid hormone level can be checked in one’s body through parathyroid hormone test or PTH. This test is done to measure the parathyroid hormone level in one’s blood. This test is also used to help identify if an individual is suffering from hypothyroidism. It may be used as well to check or find the cause of abnormal calcium levels. The parathyroid hormones or PTH are the ones responsible in controlling calcium and phosphorus in the body. Parathyroid hormones are produced and secreted from the parathyroid. Parathyroid glands are pea-sized glands that can be found just at the back of the thyroid gland. The parathyroid glands release more parathyroid hormones if the calcium in one’s body is low. When the parathyroid glands release more parathyroid hormones, it causes the bones to release more calcium into the blood and reduces the amount of calcium released by the kidneys. The parathyroid glands should just release enough parathyroid hormones needed by the body. If the body has too high or too low in parathyroid hormones, it may cause problems with the kidneys.

Parathyroid Hormone Calcium

The parathyroid hormones play a vital role in an individual’s body. It regulates calcium and phosphorus. These hormones are produced by the thyroid gland. Its major targets find its way to the cells in the bone and kidneys. If the calcium extracellular fluids are below normal, it simply means that the body is not getting enough parathyroid hormones from the parathyroid glands. The parathyroid gland stimulates the mobilization of calcium from the bone. Studies show that the effect of parathyroid hormone is to stimulate osteoclasts or large multinucleate cells to reabsorb bone minerals, and liberate calcium into the blood. Parathyroid hormones also enhance absorption of calcium from the small intestine. Other that, the parathyroid hormones suppresses the calcium loss in the urine. In stimulating fluxes of calcium into the blood from the bones and intestine, the parathyroid hormones break the excretion of calcium in the urine, thus, it conserves the calcium in the blood. Another effect of parathyroid hormones on the kidneys is to stimulate the loss of phosphate ions in the urine.
