I respectfully disagree with meow about a diagnosis and tests. Celiac is an autoimmune disease. If she has it, correct diagnosis is imperative as it will affect her whole life. Someone with celiac will get sick from a crumb of gluten. Try explaining that when the child goes to a party or BBQ or is fed at kinder. Gluten can be in so many things from medication to make up.

I totally agree with healing the gut and the GAPS protocol is great for that. Working with a neurological chiro etc will help. Just get that diagnosis first. If she doesnt have celiac then great, but unfortunately you cant get correctly diagnosed without still eating gluten.

Try not to stress. I got to 36 before a diagnosis and that was after 3 university degrees. It's just another way of interacting with the world and if she's thriving on treatment then that 's wonderful.
