I had radioactive iodine when I was 15. I'm 20 right now about to turn 21. I had a bit of trouble at the beginning but my universe sent doctor figured that instead of just giving me the T4 he would combine T4 and T3 ( levothyroxine and liothyronine). My levels have been really good ever since and I am glad I got the radioactive iodine. I personally do recommend the radioactive iodine. That was the last option for my doctor for years and once we did it, it was amazing. I recommend talking to your doctor first because you can't get pregnant for like 6 months once you get the iodine done but after that it would be much easier to control your hormones. Once you get it the only thing you take is synthetic hormones that replace your thyroid, which is easier than TRYING to control your hormones which are constantly changing.

I had radioactive Iodine treatment when I was very young around 6yrs old. This could be just my situation I was told at that age in the future if I wanted to have children the likely hood of something complications during pregnancy or something with the baby is very high. I highly suggest you try Anything before resorting to that treatment.

I had the radioactive iodine treatment done and wish I would have never got it my doctor insisted on me getting it done ever since then my health has never been the same
