radioactive iodine and parathyroids

If the radioactive iodine kills the thyroid how can the parathyroids still funtion since they are connected to the thyroid?

Re: radioactive iodine and parathyroids

Thyroid tissue is unique, in that it takes up iodine (which it converts like a factory to thyroid hormone). Radioactive iodine is used to destroy the thyroid, because the iodine component is "sucked up" (uptake) by the thyroid tissue, and then the radioactive material can then destroy it.

My parathyroids by the way, were not even on my thyroid---they are in the area, but not necessarily on each persons thyroid.

So a parathyroid, which isn't made of thyroid tissue, should not usually be destroyed by the radioactive material, because it's designed to just destroy thyroid tissue, if that makes sense.
