XAI Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder that affects the large intestine. It is characterized by a group of symptoms that typically occur together, including abdominal pain, bloating, gas, and changes in bowel habits such as diarrhea, constipation, or alternating between the two. IBS is a chronic condition that requires long-term management.
