The parathyroid glands produce a hormone called PTH, which controls how much calcium and phosphorus you have in your blood, bones, and intestines, as well as how much phosphorus you release in your urine.

Hyperparathyroidism develops when the parathyroid produces too much PTH. Too much PTH causes your blood to receive too much calcium and your urine to excrete too much phosphorus, which can put you at risk for bone fractures and kidney stones.

The two types of hyperparathyroidism are:

  • Primary hyperparathyroidism, which results from one or more enlarged parathyroid glands
  • Secondary hyperparathyroidism, which results from a calcium or vitamin D deficiency

To care for hyperparathyroidism, we first evaluate the severity of your symptoms and determine the underlying cause of your disease. For some, hyperparathyroidism does not cause significant symptoms. In those cases, we will simply monitor your condition closely.

In more severe cases, we may prescribe medication and/or recommend surgical removal of the affected parathyroid glands. We always follow up on your condition with careful monitoring.

Our endocrine surgeons typically perform this surgery as an outpatient procedure using minimally invasive techniques with intraoperative hormone monitoring. Intraoperative hormone monitoring allows your surgeon to test your PTH level during the operation and determine if there are additional glands that should be evaluated.
