PTH (Parathyroid Hormone)

Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands, which are small glands located near the thyroid in the neck. PTH plays a crucial role in regulating calcium levels in the blood. When calcium levels drop, PTH is released to increase calcium by promoting its release from bones, enhancing absorption in the intestines, and reducing loss in the kidneys. This regulation is vital for maintaining bone health, muscle function, and overall bodily processes. Imbalances in PTH can lead to conditions such as osteoporosis or other bone disorders.
