That one I remember, it increases calcium levels. One of the first patients I had as a student was a woman who was experiencing severe carpal spasms after thyroidectomy. Seem like the surgeon also removed most of the parathyroids at the same time. A common complication back in those days.

On my board exams in 4+ decades ago it seemed like every third question was on whether calcium or phosphorus levels rose or fell with certain diseases. I must have had a lucky coin to flip that day. A modicum of knowledge of physiology helped, too.

    PTH increases calcium in the blood by increasing osteoclast activity (bone breakdown), reabsorption of calcium in the kidneys, and via the intestine where it increases vitamin D production (vitamin D causes increase absorption of calcium via calbindin).

    and that is why pharmacists don't practice medicine. Parathyroid hormone increases calcium levels in the blood. It is actually the first thing you check when someone has a high calcium. It stimlates osteoclasts to resorb calcium from the bone and also stimulates the kidneys to reabsorb more and as well as ativate vitamin D to increase intestinal absorption.
