Hi and welcome to HealingWell!
Have you tried following a gluten free diet to see if that helps with the symptoms? What carell says is correct, being scoped is the most difinitive way to be diagnosed with Celiacs. However, if you cannot afford that, I hear Prometheus Labs is pretty accurate in diagnosing via blood tests. I had samples flown to their lab to check for IBD, Celiacs and Lactose Intolerance.
Best of luck to you... please take care and keep us posted.
