PTH

Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands, which are small structures 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, prompting bones to release calcium, kidneys to retain calcium, and the intestines to absorb more calcium from food. This hormonal action helps maintain the balance of calcium, which is essential for bone health, muscle function, and nerve signaling. Proper PTH function is vital for overall metabolic health and prevents conditions like osteoporosis.
