As per previous posts, I had been on 20 mcgs of T3 and 50 mcgs of T4 for several years - and felt well, although blood tests showed I was slightly over-medicated. I'm not hugely confident with my NHS endo, although he prescribes T3, and so saw a private endo at the end of 2019 for a second opinion. He was really knowledgeable, clearly not the "average" diabetes specialist, but not a fan of T3 meds for various reasons, and doesn't prescribe them in his NHS practice. He recommended I return to the previous level of levo-only at which I felt well.
Somewhat to my surprise, when he then wrote to my GP to summarise our consultation, they changed my prescription to levo-only. I decided to see how this went, but booked an appointment with the GP anyway to discuss my last blood results [about which I posted earlier]. This is a new GP for me, who had arranged a full set of blood testing, so I was impressed with that.
After just over 2 weeks on levo-only: I have put on 2 kilos [previously my weight was stable and I even managed to lose a bit last summer]; my face is puffy; husband says hair is no longer glossy; I'm moving over to brain-fog and feeling cold.
Saw the GP just now - and happily she has restored my NHS T3
So pleased!
