PTH, or parathyroid hormone, is a crucial hormone produced by the parathyroid glands, which are small glands located in the neck. Its primary role is to regulate the levels of calcium in the blood. When calcium levels drop, PTH is released to stimulate the release of calcium from bones, increase calcium absorption in the intestines, and reduce calcium loss in urine. This helps maintain a stable level of calcium, which is essential for various bodily functions, including muscle contraction and nerve signaling.
High levels of PTH can lead to health issues, such as hyperparathyroidism, where too much calcium is released into the bloodstream. This condition can cause symptoms like fatigue, kidney stones, and bone pain. Conversely, low levels of PTH
