AI Article Synopsis

  • Irritable bowel syndrome (IBS) is a prevalent condition that leads many people to seek medical help due to symptoms like abdominal pain and irregular stool patterns.
  • It is often diagnosed through a detailed assessment of symptoms, medical history, and physical exams rather than relying solely on tests, as it's usually a diagnosis of exclusion.
  • The article discusses the criteria for diagnosing IBS and the role of various diagnostic tests in evaluating its symptoms.

Article Abstract

Irritable bowel syndrome (IBS) is among the most common diagnoses made by medical providers and its symptoms are common causes for health care consultation. IBS is characterized by abdominal pain associated with abnormal stool consistency and/or frequency and is widely considered a diagnosis of exclusion, despite abundant evidence contradicting such an approach. A positive diagnosis is achieved through application of symptom-based clinical criteria, careful history and physical examination, evaluation for alarm sign/symptoms, and judicious use of diagnostic testing. This article reviews the symptom-based criteria for IBS and utility of diagnostic tests commonly included in the evaluation of IBS symptoms.
