0.8-2.2 ng/dl. The Thyroid treatment center has ordered a radioactive iodine uptake and thyroid scan for toxic multinodular goiter and to treat with I-131 treatment.  not sure what to think. Have  alot of the symptions, but I have gained weight and have been unable to lose it.  So what is up?

Wow, you have given me alot to think about  Ok symptons first:
hot flashes,night sweats,fogginess, hair loss, muscles getting weaker,sleeping 3-4 hrs, fatigue,hard time swallowing,terrible mood swings, am sure I am leaving some out.  Blood work results:
TSH 0.10 range 0.30-5.00 MIU/ML   T4Free 1.2 range 0.8-2.2 NG/DL
T3Free 4.52 range 1.7-3.7 pg/ml  CRP(c-reactive protein) .50 range 0.01-0.82 MG/DL
IGE(Immunoglobulin e) 4.0 range 88.0 IU/ML//  B6 21 range 2.1-21.7 ng/mL
B12 384 range 208-964 Pg/ML  Vit D  30 range 30-00 ng/mL
LH (luteinizing Hormone) 31 range not sure most likely in the Luteal range 1-9, but am peri(have not had a period in over 2 years) FSH  54.6  Progesterone .60 luteal range is 1.2-15.9  origesteribe .60 Kyteak rabge 1,2-15.9.  So there it is and the Family Dr has ordered HRT

I-131 is a permanent treatment to kill (ablate) the natural function of your gland.

You have no confirmation of Graves disease so this option could be done - pre-maturely. Also no other further tests are done like in the Hashimoto theory Barb suggested with the hyper results.

Your labs indicate "hyper" but in the spectrum of things these are not terrible labs for optimal thyroid patients.

You do have some damage on the Mult-goiter but to rush on ablation may not solve anything.

You said you had other testing done. Can you list what you had and those results?

You also state that you may be a candidate for HRT which very well - if you have these other hormone issues going on the thyroid certainly good become ill and your situation could be stemmed directly from the abnormal other issues already in place.

Are you estrogen dominant? Abnormal estrogen can cause the thyroid to malfunction and not necessarily towards hypo either.

Your gaining weight - which can happen in hyperthyroid - but its not common with it. Most lose due to the metobolism speeding up and with your weight gain your doctor and you may want to look at progesterone/estradiol and testosterone levels very close to see if you have a pattern there that could be causing these issues to rise.

Also where is the weight gain? Is it a pooch belly fat? That then, should be a sign of looking at some adrenal issues first too - before assuming its all thyroid related.

No I am not on anything.  The Family Doctor ordered all the blood work for the thyroid and vitamin checks, he was just going to put me on hormone replacement therapy, and I insisted he make an appointment with an endo before I would do anything. So I went and met with the endo he looked at all the lab reports, asked me a lot of questions about my symptoms, felt my neck and set up the appointment with the hosp for the
iodine uptake and throid scan along with the I-131 treatment.  Not really sure what to think here

Are you currently on any type of thyroid med? If so, what kind and what dosage?

I would suggest that you get tested for Graves Disease AND Hashimoto's Thyroiditis.  It's very possible for a person to have both antibodies.  

I'm not that familiar with the nuclear treatments, but I agree that I'd want all other possibilities exhausted before going down that road.

There are many on this Board much more familiar with nuclear than I am, let me suggest Barb139, and a post 2 days ago about I-131 treatment.

Many make the case that Graves be ruled out before turning to nuclear. I would agree but not from the standpoint of a Doc, or person who's had the uptake themselves. Many want all non-nuclear options taken first before they go any further.

Please take a look at the posts on this from October 10th and 11th.

Best in your health.

No sonogram/ultrasound. Just went to the endo yesterday.  He looked at all the lab results, felt my throat and then scheduled  the RIUT and I-131 treatment.

I assume the iodine scan for toxic multinodular goiter has been confirmed with a detailed sonogram/ultrasound?

Your labs are hyper, but many of us who are hyper gain weight. Thryoid diseases affect our metabolism, which can be a cause of a lot of weight issues, higher and lower. This is not that unusual at all.

Can you confirm a sonogram/ultrasound diagnosis?
