I was diagnosed with an underactive thyroid (and was told my antibodies were high although doctors seem reluctant to diagnose Hashimotos) two years ago and six months later went on a gluten free diet. I did so to see if it would help my migraines. Even though its been 18 months its still early days but I think there has been a reduction in the severity of my migraines. I would be interested in finding out if going gluten free has helped anyone elses migraines. I have a strong family history of auto-immune disorder with one close relative having caeliac disease so I strongly believe it is all linked and worthwhile going gluten free even if you do not have caeliac. I would be interested in finding out if my antibodies have reduced but I don't think my GP will test me again. They only seem to want to check thyroid levels and not antibodies and their argument is its the same treatment.
