I have severe abdominal distention that happens at random times, pretty much every day. I was recently tested for celiac disease and my tests came back normal. However, I put myself on a gluten free diet anyways, and the size of my distention has gotten better but is not completely gone. I have been keeping a food journal and have noticed that the last few days, when I did not consume dairy, my problems disappeared completely. Today, I had one piece of cheese, and within hours my intestines ballooned. Could this be from only one piece of cheese. My GI doctor quickly wrote my problem off as IBS, but I know that this is being caused by something.
