I'm on t3 and t4. The doc I used to see suggested I wait until my antibodies were lower before trying ndt. They have got better (there has been a bit of fluctuation but they're better than they were when I was first diagnosed) but still were too high when last tested (tpo was around 300 and tgab was 40 or 60). Being on enough meds hasn't really shifted them, nor has a gf diet.
I don't know if I ever asked why antibodies and ndt are meant to be mutually exclusive, but I thought it was something to do with ndt being too like the natural human thyroid hormone and going the way of the hormones produced by the human thyroid, so I think the danger is meant to be that when you swap over to ndt you can become hypo (please don't quote me, I'm not a doctor, etc).
So my question is: are there people here who are succeeding on ndt with high antibodies, aka is the antibody theory a load of hooey? I'd like to give it a go, but not if I'm going to go hypo, get ill, etc and have to go back on synthetics anyway.
