About 1 year ago I was diagnosed with an under-active thyroid. During a few blood tests back then I had a TSH of 5.4 – 6.8. I avoided taking Thyroxine prescriptions and instead sought help/advice from a nutritionist. She carried out a blood test from which she concluded that my under-active thyroid was an auto-immune issue. For the past 6 months I have been taking supplements (incl a thyroid hormone) and my diet has changed (incl avoiding gluten). Overall, this appears to have been having an effect i.e. in the last 2 blood tests my TSH has been 4.00 and 4.25, which I think is very encouraging. However, my Thyroglobulin auto immune antibody reading remains high, at approx. 259 IU/mL.
I am wondering whether anybody can advise me on what conclusions to reach:
•Can I conclude that the reason my TSH level has come down is probably because I have been taking supplements (incl a thyroid hormone)? and because I have made some changes to my diet?
•However, given that my Thyroglobulin auto immune antibody reading (259 IU/mL) has not reduced can I conclude that avoiding gluten is probably unnecessary? Instead, I am likely to have a sensitivity to some other food?
•How likely is it that my auto immune antibody issue is caused by something other than food?
•What should I do next in an attempt to reduce my Thyroglobulin auto immune antibody reading? Avoid some other food(s)?
I would be extremely grateful for any responses. Thanks in advance.
