Classification of irritable bowel syndrome

Most people who have irritable bowel syndrome (IBS) have mild symptoms that usually don't disrupt their lives. They usually don't need to see a health professional, other than for reassurance that they do not have a more serious problem, such as cancer.

About 25% of people who have IBS have more bothersome symptoms that occasionally disrupt work, school, or other activities. Episodes may be related to stressful events or to eating a particular type of food. In these people, physical and emotional factors may affect their symptoms.

Only a few people (about 5%) with IBS have severe symptoms, such as abdominal pain that is much more severe than would be expected from stress, meals, or a physical problem. These people often are also anxious, depressed, or under a lot of stress, and they may have trouble acknowledging that stress-related factors may be contributing to their problem.

Sometimes people who have severe IBS symptoms visit many doctors, trying to find a physical cause for their symptoms and to find a cure. Some may believe that their doctors are overlooking a serious problem and may believe that they need more tests or treatments. This can be very frustrating. It is often helpful to get a second opinion, if possible from a doctor who specializes in treating functional bowel disorders.
