If she was fine when not eating gluten and having pain when she does, it would point to her having a gluten intolerance. Simple enough to just avoid gluten for a few months and see if that helps. As my doctor says, most of the tests used do not test deep enough and miss this.

I am sorry you didnt get a reply before. I am celiac. First off the blood test results are not great, I have heard so many people with Celiacs who the initial blood test was negative. It starts off with what Blood test did they do? Did they test for the Celiac Gene?
I could go on and on.... basicly, my advice is this.
1. If she feels good gluten free, stay gluten free.
2. Get her into a gastroenterologist they will be able to diagnose her correctly.
Good luck!

My daughter has always tested negative her whole life on every type of allergy test for milk and soy but she is very allergic. I talked to her allergist and he said it is rare but not unheard of to test negative and have an allergy. If your daughter was better off it then do what feels right! She probably has an allergy.

Yeah. Avoid gluten. It is in a lot of stuff though. So be prepared to check the labels. A lot!

Testing is a great tool and is very helpful. I have found that keeping a diary of all food and drink is extremely helpful as we are all different. It might just be the combination of certain foods that trigger your attacks. Yes it takes a bit of time but I found it well worth it and remember some people grow into AND out of allergies/intolerances.
