Irritable bowel syndrome (IBS) is a prevalent condition marked by abnormal gut contractions (motility) and heightened gut sensitivity (hypersensitivity). It manifests through symptoms such as abdominal pain or discomfort, gas, bloating, changes in stools, and inconsistent bowel habits, which may include constipation, diarrhea, or a mix of both. These symptoms are typically chronic, recurring intermittently, and can vary in intensity over time. Although IBS can cause ongoing abdominal discomfort, it does not result in serious diseases affecting abdominal organs. Diagnosis generally involves suspecting IBS and confirming it by ruling out other potential abdominal conditions. Treatment focuses on alleviating symptoms through dietary adjustments (like reducing intake of milk products and sweeteners), regular exercise, relaxation methods, and medications. IBS is also referred to by several alternative names.
