Parathyroid Hormone

Parathyroid hormone (PTH) is a hormone released by the parathyroid glands in the neck that helps the body maintain a healthy level of calcium in the blood. The hormone is critical for many body processes, including building strong bones, helping regulate the amount of calcium that is absorbed from the diet, and regulating nerve and muscle functioning. Additionally, PTH helps regulate calcium levels in the bloodstream, protecting against calcium deficiency or excess calcium. It also helps to control phosphate levels in the blood, and can also induce a variety of other effects such as changes in heart rate and volume of urine produced. PTH plays an important role in numerous medical conditions, including hypoparathyroidism, hyperparathyroidism, and osteoporosis. Treatment with PTH is effective in many of these conditions to help maintain bone health and restore normal calcium levels.
