Kerri, my TSH is suppressed also, 6+ months after RAI and on synthroid. That happens commonly when one has been hyper for awhile, and can take 3-6 months (my endo said) to start functioning normally. Were you hyper this time again?
You are about the third person I’ve talked to who was on synthroid and had some regeneration of the thyroid after RAI. Did your endo say how often this happens? Thanks. Dianne N
