Hi,Sally
RAI can damage the parathyroid glands, which are nestled around the thyroid glands. Damage may show up as an enlargement in one or more of the glands (there are 4). The enlarged parathyroid excretes more than normal amounts of hormone (PTH). This will increase the amount of calcium pulled out of your bones into your bloodstream to serve the cells in your body. This can be checked by a test of PTH and serum calcium. I just had this done. The results were high PTH, normal calcium, which is hard to explain. My physician has passed the info on to my endocrinologist; I’m still waiting for her response.
Let me know what you find out. The studies I’ve seen recommend testing of PTB every 5 years for those treated for Graves’ Disease with RAI.
If you want the references, let me know.
