I was diagnosed with Hashi in 2011 and at the time my TPO antibodies were 258 iu/mL (0-59). Two years later, and on levo, they'd climbed to 478.8 iu/mL (0.00 – 5.61) and although I was feeling quite well I decided I didn't want this to continue and went gluten free to see if I could halt and perhaps reverse the condition. 12 months on I had the test repeated yesterday and the result was 390.16 iu/mL (0.00 -5.61). So going in the right direction, albeit slowly. Does anyone know if this is good, bad, indifferent? Given how long it took me to get my diagnosis I now realise I had been ill for many years, so could quite appreciate that it might take years to go back the other way. In addition to my levo I also supplement with vitamin D and Selenium. I'd really apprecite your thoughts on this.
