I have been diagnosed as having GERD, and Barrett's Esophagus, as well I have had bone/joint pain, chronic dihharea and constipation for years and have been having floating stools periodically for the past several months. I went for endoscopy/biopsy which revealed mild folds on the duodenum. The results from biopsy came back Celiac negative. However, I'm not so sure. My father is both Celiac and suffering from leukemia. At 68 my father was diagnosed as having GERD, Barrett's Esophagus, and IBS, and he went for a biopsy which came back Celiac negative. Then at 70, he went for a blood test (he wasn't even checking for CD), and it was shown that he had both full-blown CD and leukemia. My condition looks suspiciously similar to my father's. Furthermore, CD runs in our family: my father has CD, one uncle (father's brother) has CD, my grandfather (father's side) had both CD and Diabetes type 1, and my grandmother (father's side) had diabetes type 1, parkinsons disease, and chronic renal problems. I am presently taking medication to control the GERD and have been told to lay off lactose. However, the doc told me not to worry about gluten right now, but said I could always get the blood test to see if carry the HLA gene. So to get to the point, what do you think are the chances I may latent CD or may be gluten-intolerant? And, further, do you think it is worth my while getting the blood test for the HLA gene? How indicative is this in determining whether I have latent CD or should lay off the gluten? Would love to hear your thoughts.
