T4 levels while suppressed
I’m 9 months past TT with right lateral neck dissection, and almost 8 months past RAI (150 mCi with rTSH).
The last 5 months we’ve been gradually increasing my Levo dosage. Since I’m high risk, the goal is to get my TSH suppressed to <0.1. I feel like it’s taking a lot of time to get there.
I’m currently on 150 mg of Levo, and TSH has finally dropped significantly and currently sits at 1.3 mIU/L. fT4 has raised to 26.9 pmol/L (= 2.09 ng/dL). I’m starting to feel some minor symptoms like dizziness, fasciculations and light tremors and some wieght loss. It’s all quite manageble, but I’m wondering how much I can expect this to raise further and when/if the symptoms will increase.
I can’t seem to find any literature as to what’s an expected T4 level to get TSH suppressed. Only that T4 will need to sit at a ‘high normal’ range or slightly above.
So my question to you all: What are your T4 levels while being TSH suppessed? And do you have any symptoms?
Fwiw: I’m M37 and 77kg (170 lbs).
