I was tested for thyroid problems and was very boarderline for an overactive thyroid. But it was never treated because it wasn't over the normal limit, just as high as it could be without going over.quote:Originally posted by Nikki.Roes any one suffer from thyroid problems. In the past I had an over active thyroid, had radioactive iodine to kill it and now take thyroxine. Another IBS sufferer I know had the same thing. Has any one else?
