Since being Hashi/hypo I have had phases on and off AD's. Actually I was taking AD's long before being diagnosed. So what's new!!!
However over the years I have noted that when I am not taking AD's my FT3 levels are much lower. Now I put this down to a slight over conversion issue. Caused by the SSRI. That's a guess. Naturally.
Just thought I'd throw this out there.
So if you are on SSRI's and come off them and then see your FT3 blood levels drop.......don't be surprised.
I know SSRI's affect a lot of things and work in a very complex way. Not even the doctors truly fully understand I believe. I haven't mentioned this to my GP because of course I'd be deemed MAD AS A BOX OF FROGS!!!!😀
