I cant believe this treatment still exists. For those who don't know what I-131 is a radioactive isotope (type) of iodine. The thyriod gland uses iodine for the production of thyroid hormones (thyroxin). When you give the radioactive stuff, the thyroid uses this radioactive stuff, and prompty dies. Thus the need for continued use for synthetic hormones FOR THE REST OF YOUR LIFE. The thyroid don't grow back!!!
The other option is to consume uncooked goitrogens (eg. soy, nuts, cabbage, broccoli ect.) which reduce thyroid function by limiting the amount of free iodine in the body. This is USUALLY a big NO NO for O's as they generally have low thyroids. But, in this case I think the change is warranted.
Also, exersice reduces the other building block for thyroid function by using the tyrosine for adrenalin production (as tyrosine is used to make adrenalin and thyroxin). Also check Selenium statis as its needed to regulate thyroid function.
I could go on for ever but you get the gist. There is tones of things you can try BEFORE you get injected with a radioactive posion. Once again, see your practitioner. I have saved two thyriods in my day treating people like this.
Good luck, Stephen.
