There are four parathyroid glands in our body. They are very small, about 1/ 5 of the inch and they are located on or behind the thyroid gland in the neck, or elsewhere around this area: usually two on the top and two on the bottom on each side of the neck. Parathyroid glands have sensors which detect amount of calcium in the bloodstream. They function normally to regulate calcium and phosphorus levels by secreting parathyroid hormone (PTH). PTH regulates the level of calcium in the blood, release of calciu
Calcium plays an important role in bone development and in maintaining bone strength. Calcium is also important in nerve transmission and muscle contraction. Hyperparathyroidism is a disorder of the parathyroid glands, which resulted form hyperfunctioning, or excessive secretion of parathyroid hormone (PTH). Primary hyperparathyroidism is a disorder of one (in 85% of the patients) or more than one (in 15% of the patients) parathyroid glands. This problem originates in the parathyroid glands in opposite to s
When parathyroid gland (or glands) becomes hyperfunctional and enlarged, it is ignoring our body needs and secretes too much parathyroid hormone (PTH) into the bloodstreem, causing calcium level to rise. Normal feedback mechanism that has to stop PTH overproduction is disrupted and one (or several) of the parathyroid glands loses their calcium sensor ability and starts functioning independently of the body needs. This condition of excessive accumulation of the calcium in the blood, called hypercalcemia. Pri
