The answer is Parathyroid Hormone (PTH). Steroids reduce calcium levels in the blood. This results in activation of the parathyroid hormone that is essential in the metabolism of calcium in the blood. PTH induces reabsorption of calcium from bones to restore homeostasis Ca2+ levels in the blood hence causing osteoporosis. Osteoporosis causes an increased risk of bone fractures.
