Thank you for the help! I will bring all of it up to my doctor!
Let me explain those tests first. Our thyroids make predominantly T4, but a little bit of T3. The rest of the T3 we need comes from conversion of T4 to T3 at various sites throughout the body. T4 is a "storage" form of the hormones. It basically floats around in the blood stream until cells need thyroid hormone. At that time, T4 is converted to T3, which is the "active" form of the thyroid hormones. It's also the one that correlates best with symptoms. It's the only form our cells can use. So, it's very important to monitor and control T3 (which in the case of hyper is controlled by controlling the FT4 level).
By far, most hyper is caused by Graves' disease. Graves' is an autoimmune condition in which antibodies attach to the TSH receptors in the thyroid and stimulate it to produce hormone indiscriminately. TSI (thyroid stimulating immunoglobulin) are the antibodies. It's important to establish if you have Graves'. If you don't, then further testing would be indicated to determine what the cause is.
Graves' sometimes goes into remission, sometimes for years, so ATMs (anti-thyroid meds) are typically used to control hyper first. If meds do not control it well, then a more permanent solution, RAI or surgery is usually the next step. RAI (radioactive iodine) is a radioactive pill that targets thyroid cells and kills off the thyroid non-surgically.
But, we're getting ahead of ourselves. At the moment, you haven't even tried ATMs. I'd certainly stress to your doctor tomorrow that the beta blocker hasn't helped a lot. Often, beta blockers are used at the same time as ATMs are started; they help to control symptoms until the ATMs lower FT3 and FT4 levels. I'd ask for TSI for sure, and I'd ask for a repeat of TSH and FT4, adding in FT3. Methimazole (Tapizole) is the ATM that seems to be used first by most doctors.
He did not test either of those, he only tested TSH and t4. So I should get the other two tested I am guessing. What does reverse the problem? Surgery?
FT4 is quite high. Is that all he tested? Did he test FT3 or TSI?
A beta blocker will help with some of the symptoms, but it does not lower thyroid hormone levels, so it will not reverse the thyroid problem. Even anti-thyroid meds will not reverse the problem, but they do inhibit the production of too much thyroid hormone.
TSH: .25 (Normal Range is 0.45 - 4.5)
FT4: 2.21(Normal Range is 0.82 - 1.77)
My doctor told me that the beta blocker should help reverse the thyroid problem which also confused me. My TSH was .2 and my TS4 was a 2.1. According to the scale the TSH is extremely low and the TS4 is high. I have all the lab results.
Is your doctor planning to start you on anti-thyroid meds? Propranolol is a beta blocker, and it will help with some of the symptoms (lowering HR and BP), but it doesn't do anything for your thyroid condition directly.
Do you have the results of the blood work you were diagnosed on? If so, please post them with their reference ("normal") ranges as these vary lab to lab and have to come from your own lab report. We can then comment on the adequacy of testing. If you don't have them, by all means, ask your doctor for a copy tomorrow when you see him. One of the best things you can do for yourself is to get copies of all test results and keep your own history. This is invaluable as you control your thyroid condition over the years.
If you post the findings of your U/S report, members good with imaging can comment on that.
