IBS Strikes Often

Most people are surprised to learn they are not alone with IBS. In fact, irritable bowel syndrome (IBS) affects about 1 out of 10 people or more.* IBS is one of the most common disorders seen by doctors.

There's no single treatment or cure. There are ways to manage IBS so that you feel better. 

Irritable bowel syndrome is sometimes called spastic colon, mucous colitis, spastic colitis, nervous stomach, or irritable colon. These are outdated terms.

If it Looks Fine, Why Does it Feel Bad?

Irritable bowel syndrome, or IBS, is one of a range of conditions known as "functional gastrointestinal (GI) disorders." In IBS, this "disorder of functioning" is with the way nerves and muscles are working. In the doctor's office nothing abnormal is seen on tests.

The bowels look fine. Yet there is pain, discomfort, and other symptoms that won't go away or keep coming back.

Certain signs and symptoms are the basis for identifying, or diagnosing, IBS. There is no test for IBS.

IBS is complex. It is not a risk for life-threatening diseases, but it can have a major impact on a person’s life.
