I was diagnosed with an overactive thyroid and Graves in 2010. I take Carbimazole a 5mg tablet and 7.5mg on alternate days, without any side affects. My last blood test was in October, results as follows; TSH 0.14 mu/l 0.3-5.0 FreeT3 6.1 pmol 3.8-6.0 FreeT4 12.1 pmol 8.4-19.1 I have an appointment with a consultant Thursday 2/11 who is keen for me to have Radio-active iodine therapy. I have read that it could activate my Graves . My question is; based on my recent results do I need this Therapy? Please I need advice.
