I was diagnosed decades ago with IBS by GI doctor based on symptoms. Since that diagnosis, each GI doctor (2) has accepted that diagnoses. When asked about testing, I’m told my symptoms indicate IBS. However, when I read articles in this site and on medical sites, my issues don’t match. I have moderate diverticulitis and constant flatulence. No bloating, no cramping, no diarrhea, no constipation. I do have food allergies, which I try to avoid but diary and eggs (2 of several) are in so many recipes and prepared foods. So to my original question, are there specific tests for IBS? Thank you!
