With a TSH at 0.1 and still hypothyroid symptoms I think you need to ask for an endocrinologist referral. If she refuses that, insist on a second opinion within the practice group you're seeing. Ditto the celiac testing.
If all else fails, I think you can get a Canadian home celiac test kit shipped to the US.
Yes, I have thought of that. I'm going to check with my insurance to see if I have to get a referral. If not I may just go on my own.
Can Americans buy the celiac home test? I've seen the web site before and IIRC it says they only ship to Canadian addresses. I'm in Detroit...I wonder if I can get a Canadian PO box. LOL
