The hormone responsible for raising blood calcium levels when they drop below homeostatic levels is parathyroid hormone (PTH). When calcium levels in the blood are low, PTH is released from the parathyroid glands and works to increase calcium levels by promoting the release of calcium from bones, increasing absorption of calcium in the intestines, and reducing calcium loss in urine. Interestingly, PTH also plays a significant role in the body's calcium homeostasis during breastfeeding. As mothers breast-feed and lose calcium through milk production, the secretion of PTH increases to help maintain adequate calcium levels, ensuring that both the mother and child remain healthy. Hence, it's integral for mothers to monitor their nutrition during this time!
