Your TSH needs to be high so that your thyroid will suck up the iodine, the thyroid is the only gland that uses iodine, Thyroid Stimulating Hormone (TSH) is what gets the thyroid working, that is why RAI 131 works. Thyroid tissue ***** up the radioactive iodine and it dies off. By the way, before my RAI treatment (I have cancer) my TSH got up to 186...it was awful!
Hi and WELCOME! Good ? ... I'm sure some others will jump on in with answers. I'm not sure to be honest.
