Parathyroid adenoma is a benign tumor of a parathyroid gland that makes too much parathyroid hormone. Because the parathyroid hormone is largely responsible for keeping calcium levels in balance, too much of the hormone may result in elevated calcium levels in the body, which can be high or still within the normal range on blood testing. Hyperparathyroidism means that the level of parathyroid hormone measured in the blood is high. Hyperparathyroidism is associated with a variety of symptoms, including osteoporosis, kidney stones, stomach pain, fatigue, weakness, concentration and mood problems, and more.
Adenomas are diagnosed and localized with specialized imaging and are treated with minimally invasive surgery for removal. Hormone levels will often drop to normal, within minutes of removing the adenoma.
