Primary HyperParaThyroidism is the result of one of the 4 Parathyroid glands going completely out of control. It grows in size and puts out increasing amounts of Parathyroid hormone. This steals calcium from bone and raises calcium levels in the blood. This tumor is called an Adenoma. The good news is that it is NOT a cancer. The bad news is that it can and will destroy your bones.
Primary Hyperparathyroidism and Tertiary Hyperparathyroidism both have high PTH and high Calcium levels. The treatments are very different; so it is necessary to tell them apart. This is done by Parathyroid Scan.
Tertiary HyperParaThyroidism is becoming common among older individuals. Or maybe we are just beginning to notice what it really is. The blood tests are the same as Primary HyperParaThyroidism – high Calcium and high PTH. But the cause and treatment are very different.
Tertiary HyperParaThyroidism happens when Secondary HyperParaThyroidism has been going on for so long that the “thermostat is reset too high”. The ParaThyroid Glands have been maintaining a high PTH level for so long that they forget to shut off when Calcium levels are high enough.
High ParaThyroid Hormone (PTH) levels take Calcium out of your Bones. This is good as an occasional event to cover short periods of low calcium intake. Bones store calcium for use in the body. Only recently have we discovered that the flow of calcium into and out of bones is a minute by minute process, controlled by PTH.
As long as equal amounts of calcium flow into and out of your bones daily and weekly, life is good. But, if PTH is high most of the time, you eventually drain too much calcium from your bones and you Fracture. We check PTH as part of a Complete Bone Health Evaluation. High PTH is much more common than we once thought. It is called HyperParaThyroidism and comes in 3 types.
DXA identifies only 15% of persons with increased Fracture Risk. Are you in the other 85%? To find out, you should get a Complete Bone Health Evaluation. And that is…….
First and foremost, it is an entire office visit devoted to bone health. That gives you and your doc enough time to fully discuss bone health issues. Next there is the full panel of tests: DXA, VFA, CBC, CMP, TSH, PTH, and 25-hydroxy Vit D level. Finally, there is FRAX.
