I was only diagnosed as hypothyroid 8 weeks ago and have been on levo for 7 weeks. I am getting the results of my first bloods since being on levo, on Friday. Trying to inform myself, so apologies if this is a basic question.
My question is this: If low FT3 causes hypo symptoms, how is it possible that TSH can be reduced by levo, but your FT3 does not increase? I thought that your body only reduces TSH production if more FT3 is being produced? If my TSH levels have gone down into normal range on Friday, why would this be? I don't feel any better (except for an initial spike in the first few days where I felt really, really well), so I'm guessing that my body still isn't using the FT3.
Is it not only FT3 that can switch TSH off? I really hopes this makes sense. I'm getting very confused!
