Which condition is commonly abbreviated as IBS?

Irritable Bowel Syndrome, commonly abbreviated as IBS, is a functional gastrointestinal disorder characterized by a group of symptoms that typically include abdominal pain, bloating, and altered bowel habits such as diarrhea and constipation. The exact cause of IBS is not fully understood, but it is thought to arise from a combination of abnormal gastrointestinal tract movements, increased sensitivity of the gut, and psychological factors. This condition is prevalent and affects a significant portion of the population, making it important for medical professionals to recognize and understand its common features.

Understanding this definition and its implications is crucial as IBS differentiates itself from other bowel disorders by its functional nature, meaning that while symptoms are real and impactful, there are no identifiable structural abnormalities in the intestines. This distinction helps guide the approach clinicians take towards diagnosis and treatment, focusing on symptom management and lifestyle modifications.
