What are the parathyroid glands?

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.
Endocrine glands. Normally four glands - two on each side of the neck with secrete parathyroid hormone and control the blood calcium.
Parathyroid glands. He parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone. Humans usually have four parathyroid glands, which are usually located in variable manner on the posterior surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest (mediastinum) or even the thymus.[1] parathyroid glands control the amount of calcium in the blood an.

What happens if one of your parathyroid glands is damaged?

Three more remaining. There are four parathyroid glands situated in the neck, behind the thyroid gland -- two on left and two on right, usually a few centimeters apart. These glands make parathyroid hormone (PTH) that control calcium and bone metabolism. Usually only 0.5 to 1 parathyroid is sufficient to make enough pth. If 3 to 3.5 glands are damaged or removed, the body can still maintain PTH and calcium control. Read more...
Redundancy. You only need one functioning parathyroid to lead a healthy normal life. This anatomical fact makes thyroid surgery largely safe. Sometimes parathyroids can be removed or damaged during thyroidectomy. Read more...

What complications come in romoving th parathyroid glands?

Low blood calcium. If one parathyroid gland is removed complications are unusual. If all 4 glands are removed blood calcium levels develop immediately and if untreated lead to tingling and cramps and occasionally a seizure. A nerve supplying a vocal cord could also be damaged and cause hoarseness. Read more...
Some. Parathyroid surgery risks include anesthesia, bleeding, infection, scar, injury to nerve that moves vocal cord, need for further surgery/failure to remove all necessary glands, and need for oral supplementation. In experienced hands, this is minimized. Ask your surgeon their experience with this procedure. Read more...

What are the hormones secreted by parathyroid glands?

Parathyroid hormone. The parathyroid glands secrete a substance called parathyroid hormone. This hormone is heavily involved in calcium metabolism. Calcium is vital to proper functioning of the heart, muscles, nerves, and bones. Read more...
Parathyroid hormone. The parathyroid glands secrete parathyrid hormone. This hormone is important in keeping calcium levels stable in the blood. It does this by removing calcium from bone, activating vitamin d and increasing calcium removal from the urine (so less calcium is lost in the urine). Read more...
