    When to Use
    Pearls/Pitfalls
    Why Use

    Patients being evaluated for possible IBS.

    • The Rome III criteria help diagnose irritable bowel syndrome (IBS).

    Points to keep in mind:

    • There remains no objective reference (i.e. ‘gold’) standard for IBS; the criteria were developed through a literature review and consensus process.

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

    Critical Actions

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