You can look at irritable bowel syndrome (IBS) in two key ways: what it is, and what it’s not. That’s because a syndrome is really a group of symptoms that occur together, with no visibly obvious cause.

Because of that, there’s no one test that can diagnosis IBS; to determine whether you have it, doctors must first rule out other possible conditions, according to Anthony Starpoli, MD, gastroenterologist in New York City.
