Struggling For A Diagnosis in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted January 5, 2007 · Report to Admin It is 12 years since the onset of my symptoms and I'm still not diagnosed other than IBS and thyroid autoimmune disease. I feel better on a gluten-free diet and have always suspected Celiac, but without a proper diagnosis I too have altered on and off a gluten-free diet. I have had two colonoscopies, an endoscopy, blood screenings for celiac, lupus, rheumatoid arthritis, fibromyalgia, lymes, several barium x-rays and a spinal tap for MS, all negative fortunately, but leaves me undiagnosed. I have seen physicians, gastroenterologists, rheumatologists, neurologists, endocrinologists and homeopaths...You know the drill for diagnostic tests...unpleasant, humiliating, scary, stressful, frustrating, expensive and time consuming. I drew the line when my GI doctor wanted to schedule me for a biofeedback test that entailed filling my colon with barium and monitoring the elimination. I thought, you have got to be kidding me! I now make an effort to be gluten free and if time cures my symptoms and this forum gives me guidance, I will be happy with that! Consider yourself lucky!
