Thyroid uptake and scan

[Wantingnormalcy]

A few months ago (mid June)I had levels tested due to multiple HYPO symptoms and blood tests can back severely HYPER.... and the dr scheduled me for an uptake scan immediately. (I never got the specific numbers) so I went in on June 20th and took the radio active pills and the next day did the scan. About a week later I got a voice mail saying my scan was "normal" and I needed to come back in about a year for more blood tests to recheck levels . Since my uptake about 2 months ago I have gained 14 lbs (and I am not pregnant... Trust me!) I lead a very healthy life style , exercise regularly and try to maintain a 80% raw diet. I am 5'7 and In June I weight 135 and now I am 150.... My question is can the uptake upset the thyroid to the point of such aggressive weight gain? I have even upped my workouts to try and counter act since I am so miserable. I read a lot of posts of specific free t3 and 4 levels and uptake results, but I have not received my exact numbers, so sorry I can't post (I will try to call and get them if it will help suggestions and input). I guess my question is has anyone had HYPER blood results and HYPO symptoms, or weight gain after an uptake ?

While many doctors tell us that weight gain with hypothyroidism should only be 5-10 pounds, many of us who have been there/done that know that's certainly not the case, particularly if treatment for hypothyroidism is not adequate, as we see all too often.

I can't say if your weight gain is excessive but generally weight gain with hypothyroidism is more modest in the neighborhood of 5-10lbs or so I've read. Since the purpose of your treatment was to correct an overactive thyroid, I'd expect a little weight gain since your metabolism rate should have slowed. Your activity and caloric needs to maintain your old weight will not be the same as before.

It *is* possible you are now hypothyroid. Whether or not that's really the case can only be determined by bloodwork to evaluate your  thyroid function. If you're concerned about the weight gain, I'd speak to your doctor who can order bloodwork and treat you accordingly. If your labs come back normal you may just need to increase your activity further and/or decrease you caloric intake.

Best of luck.

Is the weight gain a result of the thyroid scan? NO
Did it damage my thyroid?!?
In order to cause acute thyroid damage it must be I-131, not  Iodine-123  and in 20 times larger dose that normally given for function scan.
The  medicine is needed to treat hyperthyroid symptoms, viral infection (If present), and anti-inflammatory medicine (Ibuprofen, for example)

In order to adequately assess your status, we really do need to have a look at your test results and their reference ranges shown on the lab report.  Also, if tested for Vitamin D, B12 and ferritin, or iron, please post those, with ranges also.

Thanks. Would medicine be needed? Is the weight gain a result of the thyroid scan? Did it damage my thyroid?!?

I will not directly answer your question but I can speculate that you may have had sub-acute thyroid inflammation of viral origin (brief preiod of hyper but the I-123 uptake is low normal or normal); the inflammation may end up with low thyroid function so you could be actually hypo right now
