How do the parathyroid glands work?

Calcium regulation.: The parathyroid glands are continously checking the calcium level in the blood. If the level drops too low, the gland produces more parathyroid hormone (pth), which has several actions to promote calcium coming into the blood. The gland also contains c cells, which make a separate hormone, calcitonin, which has some effects on bone metabolism.
Dr. Nader Kalantar

Regulates calcium.: They make parathyroid hormone (PTH), which regulates the body's calcium and phosphate levels. These levels are important for normal nerve and muscle function. PTH tells bone to break down and release calcium into the blood. In the gut, it converts vitamin D to its active form which absorbs more calcium. It also tells kidneys to allow less calcium and phosphate to leave the body through urine.

Dr. Joseph Roosth
Internal Medicine 36 years experience
Parathyroid Glands: The parathyroid glands are 4 small groups of tissue that sit behind the thyroid gland. They make parathyroid hormone or PTH which is involved in calcium metabolism. Too much PTH causes the calcium level in the blood to go up. An overactive parathyroid gland is often diagnosed when a routine blood test shows a high calcium level.

What does the parathyroid gland do?

Dr. Melissa Young
Endocrinology 10 years experience
Regulate calcium: The parathyroid glands secrete a hormone that keeps the level of calcium in the blood from falling. It does this by pulling calcium from the bone and by preventing loss of calcium through the kidney. It is also necessary to convert vitamin d into its active form, which in turn increases calcium absorption in the gut.
