This article would be really useful to show your doctor. Dr Kamran Rostami wrote this in the British Medical Journal and it has proved useful for patients to show doctors who have yet to hear about NCGS or gluten related disorders other than coeliac disease.
We have moved on a bit since this and there are other doctors across the world now very involved in this field and pushing our knowledge forward I am pleased to say (see the free Gluten Summit here). But, I have found that British GPs will take note of something written by one of their own in their most well-respected journal!
I hope it helps..
