Weight gain after RAI

I have hyperthyroidism and im going to get radioactive iodine treatment for it,i would like to know if anyone that has had it if they had severe weight gain after the RAI.

I have not had RAI, but I can tell you that you will eventually go hypo, of which one of the main symptoms is weight gain; however, it's possible that you won't gain weight, particularly if you eat well and get exercise.

Everyone reacts different to things. I believe some do, some don't. I did gain weight; however, I needed too. I was down to 88 due to my thyroid. I had the RAI, then had the TT.

I gained the weight after the TT, once I went hypo, I think I gained about 20-25 lbs at the most; stayed that way for about a yr, then I got my medications correct (after a yr.) & just started eating healthier.

This was about 17yrs ago, currently under weight at 107 (5'2, so NOT by much), but I do eat a lot healthier as I said. I was amazed how cutting out regular soda, & stopped eating fast food I dropped my weight pretty quickly. I am not a sweet eater either though, so that may help a lot, can't eat ice cream or have milk. I had gotten so burnt out of fast food. I do every now and then eat fast food, but far few & between....when we do go out to dinner or lunch, it is always grilled chicke, I love grilled chicked...
