Irritable Bowel Syndrome, or IBS, is a common gastrointestinal disorder that affects the large intestine. It is characterized by symptoms such as abdominal pain, bloating, gas, and changes in bowel habits, including diarrhea and constipation. The exact cause of IBS is not fully understood, but it may involve a combination of factors like gut sensitivity, diet, and stress. Diagnosis of IBS typically involves ruling out other conditions through medical history and tests. While there is no cure, management strategies include dietary changes, stress management, and medications to alleviate symptoms. Many people with IBS can lead normal lives with proper care.
