GlutenFreeDaduk

I was diagnosed with Coeliac disease 6 months ago. This was in the form of a blood test as my tTg-IgA was high in the 40's. I haven't eaten gluten this whole time now but my dietician would like me to have an endoscopy for a definite diagnosis. I have been advise to contain gluten in my diet again for the next 6 weeks, I am kind of worried having not eaten...
