I had a total thyroidectomy 9/10/03. I am currently going through the low iodine diet in preparation of the radiation therapy. I am extremly nauseous and in the last few days I have diarreah. Has anyone else had these type of symptoms. I have spoken with nuclear medicine and the suregeon and both do not think it is releated...this has been going on for a little over a week now. Any suggestions or comments I would gladly accept.
