If you have IBS, have you been tested for Celiac disease?IBS is a diagnosis of exclusion - or in every day terms: it is a catch-all for specific gastro symptoms that can't be classified as anything else. Doctors have ruled out more serious conditions like Crohn's and Colitis (Inflammatory Bowel Disease - "IBD"), cancers, and some infections. But more and more studies are indicating that those diagnosed with IBS should ensure that doctors have also done the appropriate tests to rule out Celiac disease.One literature review looked at the chance of people with the symptoms of IBS actually having IBD, colorectal cancer, or infectious diarrhea. 1 This literature search concluded that the likelihood of having one of those 3 conditions was less than 1%; however, in sharp contrast, people with an IBS diagnosis were 10 times more likely to have Celiac disease than the general population. The authors recommend at least performing blood tests to check for Celiac disease.In an actual trial, as opposed to a literature search, 105 people diagnosed with IBS and 105 controls were studied. 2 Interestingly, controls were chosen from siblings who had no symptoms. Blood tests were first performed on everyone in the study. If these were positive, a biopsy was done to confirm the diagnosis. Celiac disease was found in 12 of the IBS patients (over 10%), but in none of the controls. The implications of this missed diagnosis are quite profound. People with a diagnosis of IBS are often resigned to gastro upset and will often stop pushing for a solution to their symptoms. More importantly, they will continue to eat gluten, and thus continue to damage the microvilli in the gut.1. Cash BD, Schoenfeld P, Chey WD.
