Re Celiac Disease and/or gluten intolerance.I have had the test for Celiac Disease (small bowel biopsy). It was negative. However, my gastroenterologist did say, that you can still be intolerant to gluten, but not have Celiac Disease. The symptoms are so similar, this makes sense.I have eliminated a lot of gluten from my diet. For those who don't know, gluten is the protein found in wheat,oats,rye,barley and millet, I think. I eat gluten free bread and rice pasta etc. I feel better when I do this.Not as constipated. So maybe I am intolerant to gluten.I am 99% sure that wheat constipates me. Sharon
