Rome IV Criteria Overview

The Rome IV criteria are the gold standard for diagnosing functional gastrointestinal disorders, specifically Irritable Bowel Syndrome (IBS). These criteria move away from viewing IBS as a diagnosis of exclusion and instead use a symptom-based approach.

Diagnostic Criteria

Recurrent abdominal pain, on average, at least 1 day per week in the last 3 months, associated with 2 or more of the following:

  1. Related to defecation.
  2. Associated with a change in frequency of stool.
  3. Associated with a change in form (appearance) of stool.

Diagnosis = Pain + (2 of 3 associated symptoms)

Frequently Asked Questions

No. IBS is a disorder of gut-brain interaction. It affects how the gut functions but does not cause inflammation, ulcers, or permanent tissue damage.

Unintentional weight loss, nocturnal diarrhea, blood in stool, or an onset of symptoms after age 50 warrant further investigation for organic disease.
