Irritable bowel syndrome (IBS)

Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine, or colon. IBS usually causes cramping, bloating, abdominal pain, gas, diarrhea and constipation. It is a chronic condition that needs to be managed long term.

Despite the uncomfortable symptoms, IBS does not cause changes in bowel tissue or increase your risk of colorectal cancer.

Only a small number of people with irritable bowel syndrome have severe signs and symptoms. Some can control symptoms by managing diet, lifestyle and stress. Others will need medication and counseling.
