What Is Irritable Bowel Syndrome?
9. Diagnosis
There is no single test that can confirm a diagnosis of irritable bowel syndrome. Instead, the doctor will need to look at your medical history and request tests that will help to rule out other causes. One particular condition that experts are likely to look for is celiac disease, which is an allergy to gluten.
If needed, a colonoscopy can be requested, and imaging techniques may also be used. Laboratory tests may also be performed, including breath tests that will help to determine the presence of certain bacteria in the digestive system. Stool tests may also be undertaken. Once other conditions have been ruled out, experts will then see if your symptoms meet certain criteria and if they do, IBS can be diagnosed.
