Hello,
I myself had Graves disease (hyperthyroid) and went with the radioactive iodine treatment.
I don't really have a suggestion as to which you should go with, the radio iodine or the chembizole. I never had anit-thyroid meds like chembizole so I don't know the effects it has on the body and the % of it working for some patients. When my Endo doc sat me down and explained it to me, he told me there is only a certian % chance of the anti-thyroid meds actually working, on top of the risk of it causing damage to the liver, etc. Also that if the anti-thyroid meds don't work, you'll be back to the choice of radio active iodine or surgery to take out the thyroid. I don't know how true that is, this is what he told me.
He also told me that if I went with the radio active iodine route or surgery, that the meds for hypothyroid wouldn't have as many side effects compared to the anti-thyroid meds. Believing him, I went with the choice of Radio active iodine in Oct 10th or last year.
So far becoming hypothyroid had been a bumpy road. My endo first placed me on generic levothyroxine, which I read isn't the best compared to others like Sythyroid. When I was on generic Levothyroxine, I felt like complete trash. I kept having chest pain and discomfort on and off and eventually it got very very bad that I had to go to the ER. I kept telling my Endo's nurse that I've been feeling very bad with the chest pains, as well as my knees hurting all the time and she pretty much ignored me saying it was something else causing the problem. I felt so stuck. I started researching myself, reading around, and asking questions on forums like this one, and found many answers to why I was having these problems.
Problems with the chest pains, came from the dosage of the Levothyroxine the doctor first put me on. Everybody's body is different, and some can not start off with a high dose of Levothyroxine. I was one of them. The moment I cut my Levothyroxine pill in half, the chest pain went away almost immediately. I try to explain this to the doctor and his nurse but they still were giving me a hard time at addressing other issues caused by either the Levothyroxine or hypothryoid itself.
I decided to switch to a Holistic doctor, in which she placed me on Armour thryoid meds (desiccated thyroid hormones) and have felt much better. I no longer felt like complete trash compared to the generic Levothyroxine. I did still have some problems like joint pain still, lack of energy, bad heartburn and some tooth loss, but apparently that was also the fault of my doctors.They never did any blood work on my mineral panel, and the whole time I've been hypothyroid for months, my body had developed extremely low vitamin D and iron. In fixing both the vitamin D and iron I feel a whole lot better. I don't have joint pain anymore and my energy has picked up, no more heartburn and don't seem to be having tooth loss anymore.
I still don't feel at my 100% like I did before the hyperthyroid happen, but it seems to be slowly working it's way up there.
Anyways, long story short, that's what I've expereniced thru going the route of getting radio active iodine. If you do choose to go that route, just make sure you stay on top of everything. All the bloodwork you need to include a full mineral panel,b-12, folate, magnesium, potassium, calcium, sodium, glucose,iron, vitamin D, Thyroid antirbodies,TSH, Free T4and T3, and Reverse T3,adrenal testing, etc. If you're feeling certain
symptoms that you haven't felt before you started becoming hypothyroid, do alot of research first and ask around, cause most likely it's something caused by the medictions you're placed on, hypothryoid itself, or problems caused by hypothroid. I myself couldn't not rely 100%on my doctors to know what to check for or change to slove my problems, even tho you think you can trust them to know what they're doing cause they're specialists. No, you must keep on top of things yourself.
So again, I can not suggest to go one way or the other. Do a lot of research, read, ask around on forums like this, before making a choice. Either route you go, just keep on top of everything. If things don't feel like their working then you make have to go another route, try a different med, etc.
