Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. It is a chronic condition requiring long-term management. Unlike other bowel diseases, IBS does not cause changes in bowel tissue or increase your risk of colorectal cancer.
IBS primarily affects how the digestive system functions, causing symptoms like cramping, abdominal pain, bloating, gas, diarrhea, and constipation. These symptoms vary from person to person and can range from mild to severe.
