My sister has had some blood work showing the possibility of celiac disease. She is 70 years old and is asymptomatic. Her Dr. wants to do a biopsy of the small intestine but she doesn't want to. That's where my question comes in. I know that that celiac disease is inherited, but my parents, who are both deceased, were never diagnosed with celiac. They both, as well as my only sibling, have diverticulosis. I, however, have much flatulence which has become quite embarrassing at times. I have no other symptoms that might relate to celiac disease. What should I do, especially to control the gas?
