Common Questions and Answers about Graves disease normal t3 t4
graves-disease
Many hypo patients taking significant doses of T4 meds find that their body does not adequately convert the T4 to T3 and they end up with a Free T3 level that is too low in the range for them to feel well.
If you will please post your thyroid test results and their reference ranges, members will be able to assess the adequacy of your testing and treatment.
Hello. I'm 36 and I am almost 9 weeks pregnant. I have Graves' disease and had radiation treatment back in 2009. I hadn't been taking my thyroxine constantly for a few months as I was super stressed and now that I am pregnant haven't missed a dose. My thyroid levels are still very high and I'm worried that this will affect my baby's brain development/IQ levels. Has anyone else had similar experiences? I'm scared and worried.
What are your actual T4 and T3 results and were they Free T4 and Free T3 or were they Total T4 and Total T3? They aren't the same tests and don't give the same information. If you have those reports, please post those results, along with the corresponding reference ranges, which vary from lab to lab and have to come from your own report(s).
A warm nodule indicates one that might be producing thyroid hormones independently of the thyroid.
I think you have Grave's that has gone into remission.
You do not have Hashimoto's.
I think there is another problem going on as well, or your TSH would be high. Also, if you have Grave's and it is in remission, you should not need the Methimazole OR the Levoxyl.
If your Grave's is in remission your T4/T3 should be in a normal range. They are within "lab limits", but you are hypothyroid.
Something else is going on. I hope the new doctor figures it out.
Thanks for the information on the total T3 and total T4. As you probably know, TT3 and TT4 are not nearly as useful as free T3 and free T4. Is there any way you could ask your doctor to test the frees?
Your symptoms sound very hyper, which is consistent with your elevated T4. Most thyroid disease in the developed world is autoimmune...Graves' (hyper) of Hashi's (hypo, but can swing hypo to hyper in early stages).
what counts is your Free T3, Free T4 levels and symptoms .... Free T3 and Free T4 are the actual thyroid hormones, with Free T3 being the active hormone - meaning it's available for immediate use, while Free T4 must be converted to T3 before the body can use it.
Do you know if the T4 is free or total? Also, what is the reference range? That's very important because we need to know where your results fall within the range.
TSH and T4 are much more important in this case than T3 (not necessary to measure and we don't treat w/T3 when pregnant or trying to conceive). Antibodies are associated w/ infertility/miscarriage. If you had Graves' and become pregnant, test TSI levels about week 24-26. TSH goal for now is low-normal range.
I have early stages of graves disease. I have only a high t3 according to normal levels, but all the symptoms...full blown. How do I get someone to treat me based on symptoms, not numbers? My levels in June were
tsh 3.7
t4 7.0
freet4 2.6
this week they are
tsh 2.68
t4 10.4
t3 40
freet4 4.2
how bad do they have to be to get atm meds? help! They put me on clonazepam too, doesn't that cause hyperthyroid to worsen?
I finally saw an endo last week and she thinks I have Graves but my test results today show free T3 and T4 within the normal range even though TSH is suppressed.
I was supposed to have RAI uptake scan today with ablation treatment to follow but had to cancel due to a CT Scan with contrast I had done last week. I guess I'm just looking for support from others like me.
Have you been tested for thyroid antibodies to make sure you do, in fact, have Graves disease and are not simply in a hyper phase of Hashimoto's? Both Graves and Hashimoto's are autoimmune.
While Graves is always connected with hyperthyroidism, Hashimoto's is most often connected with hypothyroidism, however it's not uncommon for one to have periods of hyperthyroidism in the beginning stages.
You should ask for thyroid antibody tests.
Of course you will need a full daily replacement amount of thyroid hormone, and most doctors only prescribe T4 meds like Synthroid, which frequently results in inadequate conversion of the T4 to T3 and thus less than optimal levels of Free T3. Many doctors prescribe just enough T4 med to bring TSH back to a level that suits them. This does not work because typically Free T4 will remain too low and Free T3 even lower in its range.
The most recent labs are normal - the other labs are unusual but likely represent a hypo phase of autoimmune thyroid disease. The higher T3 compared to T4 is not unusual with Graves. It may take some time for things to settle out -- at this point, no specific thyroid treatment is needed and would continue to monitor.
Looks like Graves' disease based on the significant elevation in T3 however to confirm this a TSI blood test or I-123 nuclear uptake would be required.
When referring to T3 and T4, always specify FREE T3 and FREE T4, as they are different from the tests for Total T3 and Total T4. If you don't specify, you will get Total T3 and Total T4, which are considered obsolete and of little value.
Definitive test for Graves is TSI.
While Hashimoto's is most often associated with being hypo, it can also be characterized by periods of of hyperthyroidism, and "swinging" from hyper to hypo.
m having my worst symptoms, and my TSH is at 1.2. No doctor has wanted to test my Free T4 and T3, because I'm only 20, so everyone just chalks my symptoms up to teenage depression, anxiety, and birth control side effects. I can not gain weight, my metabolism is super fast, my appetite is making it so I always snack Yet, my heart is continuously tachycardic, my hand trembles, I don't sleep well, my temperature sensitivity is insane, and I am always tired and groggy.
