I have suspected that I might have a sensitivity to gluten and have been experimenting with elimininating it from my diet. I mentioned that to my rheumatologist so she did a blood test to determine if I had Celiac disease. It came back negative. However, she said the only way to know for sure is to do an intestinal biopsy (I think...did I get that right?) Anyway, some of the gastric problems seem better when I'm 'off' gluten. And, when I re-introduced some back into my diet, I did experience some of the bloating, gas, etc. that I had before. So, is it possible to have a problem with gluten without having Celiac disease? Or, am I barking up the wrong tree here?
