I am noticing some changes since I started a gluten free diet 10 days ago. I have controlled lower gas somewhat with vsl#3 and a low fructose diet, but now that I have cut out gluten my gas production is down to almost nonexistent. The anal itching I have had has disappeared. I know it is way too early to tell but I am encouraged. The burping and reflux remain which makes me believe that it is a separate problem from the lower gas. The doc at enterolab is very helpful and does not charge for his time. He claims it is his gift to humanity. I do recommend people get tested for gluten intolerance at enterolab. I emailed Dr. Lynn Chang at UCLA my results and basically she said enterolab is controversial but she sure did not dismiss it. www.enterolab.com
