    Rome II Diagnostic Criteria for Irritable Bowel Syndrome (IBS)

    Provides criteria for diagnosis of irritable bowel syndrome (IBS) within 3 month period.

    INSTRUCTIONS

    The Rome IV Criteria are now recommended as an update to these criteria (May 2016).
    When to Use
    Pearls/Pitfalls
    Why Use

    Patients being evaluated for possible IBS.

    The Rome II Criteria, developed through a literature review and consensus process, defined the diagnosis of Irritable Bowel Syndrome (IBS) until the Rome III and subsequently Rome IV Criteria refined them. There remains no objective reference (i.e., ‘gold standard’) for the diagnosis.

    The symptoms that define IBS are generally subjective and self-reported, making a classification system helpful. Moreover, there is some evidence to support the notion that patients who meet formal Rome criteria are more likely to respond to some therapies.

    Patient must have at least 12 weeks of abdominal discomfort or pain, which need not be consecutive, in the preceding 12 months with at least 2 of following 3 features:
    No
    Yes
    No
    Yes
