Rome III Diagnostic Criteria for Irritable Bowel Syndrome (IBS)
2006 Rome consensus definition of IBS (superseded by Rome IV).
Rome III Diagnostic Criteria for Irritable Bowel Syndrome (IBS)
Recurrent abdominal pain or discomfort at least 3 days per month in the last 3 months, with symptom onset at least 6 months before diagnosis
Pain improves with defecation
Onset associated with a change in frequency of stool
Onset associated with a change in form (appearance) of stool
ResultCriteria not met
Symptom pattern does not fulfil all required Rome diagnostic criteria for irritable bowel syndrome (Rome III); consider alternative diagnoses or further evaluation.
- Supportive features present
- 0 of 3
When to use
- Applying the 2006 Rome consensus definition of IBS; largely of historical or comparative interest since Rome IV is now the preferred current criteria set.
Formula
Recurrent abdominal pain or discomfort at least 3 days/month in the last 3 months (symptom onset >=6 months before diagnosis) plus 2 or more of: improvement with defecation; onset associated with a change in stool frequency; onset associated with a change in stool form.
Pearls and pitfalls
- Rome IV removed "discomfort" and requires pain at least 1 day/week rather than 3 days/month.
