Just one of those boring blood tests. Mine came back negative, but as nasty symptoms carried on I had another examination which ruled out damage to my gut. Nevertheless I was advised by the consultant to follow a gluten free diet.
The diet is easy to get the hang of. My brother and sister are both Type 1 and have Coeliac disease - as for me, I am highly gluten intolerant and have to eat none of the stuff. Coeliac UK website has loads of help and advice for anyone new to it. https://www.coeliac.org.uk/gluten-free-diet-and-lifestyle/food-shopping/food-and-drink-directory/ And good luck. (I now eat fewer carbohydrates and don't miss them - much.)
