      Hypo is short for “hypothyroid” . In this condition, there is not enough thyroid hormone being naturally produced to sustain cell metabolism in the body. All the systems slow down (much the way they revved up when we had too much thyroid hormone.)

      RAI does not necessarily “kill” the entire thyroid, nor is it necessarily intended to do so. Some RAI treatments are designed to leave some thyroid tissue still functioning. Some treatments are designed to get rid of more than a majority of the gland, even all of it. But the dose of RAI given is a bit of a guess (based on the size of our thyroid and the level of hyperactivity), and sometimes, albeit rarely, an initial treatment does not get rid of enough of the thyroid to eliminate, permanently, hyperthyroidism.

      How long it takes for thyroid cells to die out after RAI varies with the amount of RAI given, and our own body’s reaction to it. A rule of thumb that I’ve read is three to six months. The effects can usually be seen before then, but the complete results take longer. I was technically hypothyroid four weeks after my RAI treatment.

        RAI has been interesting for me. I had two doses of radioiodine last year (2/97 and 4/97). The first time they tried to calculate a dose that would disable a portion of my thyroid and leave me with normal hormone levels. When I continued to be hyper after that treatment, I was given a second treatment intended to “kill off” my thyroid. At the end of January, 98, my doctor had me discontinue taking any replacement hormone because I was still hyper. I need to wait for 8 weeks and then they will test me again. Most everyone I’ve talked to only had one dose and have been extremely surprised at my experiences.

          Bobbi. You said that you were technically hypo four weeks after RAI. Did you then start taking hormone replacents? How long did it take for you to feel normal again –feel good? I’m going to do an RAI and I feel real nervous about killing my Thyroid and then not feeling normal or good for a long time. Please let me know your experience. Thanks
