Irritable bowel syndrome (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, including gut motility, sensitivity, and the gut-brain connection. Diagnosis of IBS typically involves ruling out other conditions through medical history and tests. While there is no cure for IBS, management strategies include dietary changes, stress management, and medications to alleviate symptoms. People with IBS often benefit from working with healthcare professionals to develop a personalized treatment plan.
