Recurrent abdominal pain or discomfort, 3 days per month in the last 3 months (12 weeks), associated with ≥2 of the criteria below. The criteria are fulfilled with symptoms onset 6 months prior to diagnosis.

Advice

The Rome III criteria are helpful in classifying patients and for determining potential therapies.

We are unaware of validated management algorithms using the Rome criteria.

Critical Actions

IBS is a ‘rule-out’ diagnosis, which is to say all other possibilities must be ruled out first.
