Treatment of excess parathyroid hormone including evaluation for causes, medical treatments and referral for surgical treatment as needed help save bones! Vitamin D deficiency or an adenoma or nodule in the parathyroid gland, are the two main reasons why patients have hyperparathyroidism. The symptoms are very subtle and include irritability, bone pain, and nausea or diarrhea, all nonspecific and seemingly caused by other medical conditions. Together, they lead to long-term changes in muscle strength, and bone strength, if the underlying high parathyroid hormone levels are not addressed. We find clues to what causes the hyperparathyroidism, we send people to get surgical treatment when needed, and we follow to make sure that the problem resolves: all to help improve the quality of life.
