the recent thyroid levels look normal at this point -- 49 is not an unusual age for menopause and not all women have hot flashes, etc.  It usually takes 3-6 mos to go hypo after RAI but may take longer.  Testing thyroid at least every 6 months is imortant in your case

Hi Sandy, I hope you are still out there reading. Sorry your post wasn't answered before now. I had expected the doctor to answer.  Until he does here is my input and a short back ground of my thyroid history.  I am 10 years RAI treated Hyper/Graves', with nodule and TED 2 years after treatment.  I think I answered some of your other post.

I have know of women who did RAI that still wasn't on meds after 5 years.  I have lost contact with them but I am almost sure that they must be on meds. by now.

When you will go hypo enough for meds. is really an individual process, with many possible factors factors such as: What the doctors goal  was i.e. to totally ablate or leave a little function. Reason for the RAI, dose of RAI,   was the correct dose amount  given i.e.  RAI dose is not an exact science therefore the dose could have been miscalculated.  How tough thyroid you have i.e.  some are so tough a first RAI will not take therefore will need a second treatment dose which is not all that unusual and I have read where 2 and 3 dose treatments were need.  Up to 5 treatments is safe but they normally don't go beyond that amount.   Then for some, it might take up to 10 years for the thyroid to  totally ablate. So you see there are many factors that might influence when we go hypo from RAI.
As long as you stay in Labs reference range I would assume you would not need to go on meds. or have another RAI. However make sure you get tested on a regular bases and often to stay on top of your situation to avoid  severe situations.
I was in menopause earlier than 49, however I was not diagnosed with Graves' until years later. I did not have the night sweats/hot flashes or weight gain nor any other symptoms and I did not take HRTs. However, I believe that being hyperthyroid will bring on female problems and therefore menopause as well. I don't know about you, but I welcomed mine.
As far as symptoms being fatigued or tired all the time is a continued issue with me and a possible permanent thyroid issue.  I have to take cat-nap to rejuvenate, sometimes taking several throughout the day - good thing I don't work :) My cholesterol (family history with heart attacks and strokes) is good when I eat properly, if I don't it shows up in  the Labs.
Worry and stress is not good for us Graver's due to the autoimmune factor.  Worry and stress can make symptoms and levels worse.  Exercises, especially  yoga, is very relaxing on the body and for the mind.
The only test that I can recommend is TSH and both FTs.  Once a year a full blood and urine work up to make sure our system is up to par and fully running correctly.
This is getting too long, hope it all post, so I'll stop for now,  however I hope it finds you doing much better. If you have any more questions, I am here.
