Quick Answer

Irritable bowel syndrome (IBS) is a common functional digestive disorder. Although the intestines appear normal on medical tests, they do not function normally. IBS is characterized by recurrent abdominal pain or cramping associated with changes in bowel habits, including diarrhea, constipation, or both. It often occurs together with bloating and excessive gas.

What Does IBS Mean?

IBS is called a functional gastrointestinal disorder, meaning the digestive tract has no visible structural damage such as ulcers, tumors, or inflammation, but the normal function of the intestines has been disrupted.

Researchers believe IBS is closely related to abnormal communication between the gut and the brain, making the intestines more sensitive and affecting normal bowel movement.

Is IBS Dangerous?

IBS is not considered a life-threatening disease. It does not cause permanent intestinal damage or increase the risk of colon cancer. However, because symptoms often recur, IBS can significantly affect daily comfort and quality of life.
