Hyperparathyroid disorder is when your body makes too much of a hormone called PTH. It leads your body to take calcium out of your bones and weakens them. Taking lab-made version of PTH can build new bone and make your bones stronger.
You take this hormone therapy once a day by giving yourself a shot under the skin. You can take it in the leg or the stomach. Over time, it can make your bones denser, which lowers the chances that you'll break them.
