What are the Rome IV criteria for diagnosing irritable bowel syndrome?

• A. Pain related to defaecation, a change in stool frequency, or a change in stool form
• B. Fever and weight loss
• C. Pain related to meals and nocturnal pain
• D. Recurrent abdominal pain with two or more associated symptoms at least 1 day per week in the last 3 months

Answer: (D)

Rome IV criteria diagnose IBS by a frequency-based symptom pattern: recurrent abdominal pain at least 1 day per week on average in the last 3 months, with at least two associated features—related to defecation, a change in stool frequency, or a change in stool form. The key emphasis is the persistent, recurrent nature of the pain and its relationship to bowel movements or stool characteristics. The best answer states that there is recurrent abdominal pain with two or more associated symptoms occurring at least once a week over the past 3 months. This directly mirrors the Rome IV threshold. Why the others don’t fit: one choice lists several IBS-associated features but omits the required weekly frequency and the chronic time frame, so it doesn’t meet the diagnostic threshold. Fever and weight loss point toward an organic disease rather than IBS. Pain related to meals or nocturnal pain is not characteristic of IBS and often suggests alternative pathology.
