Finally! There have been no updates to the Rome IV criteria for diagnosing IBS since 2016.

But now the Rome Foundation has released the Rome V Criteria. This marks a new era in the classification and care of dysfunctions of the gut-brain interaction (DGBI).

IBS is one of the most common of those dysfunctions.

From the foundation:

This updated DGBI framework reflects the latest science and emphasizes a more compassionate, patient-centered, and biologically grounded approach to diagnosis and treatment. Rome V empowers clinicians to make positive, evidence-based diagnoses, moving beyond exclusion and toward personalized, compassionate care. Building on validated instruments and new translational data, Rome V integrates more rigorous scientific methods to define disease mechanisms and identify clinically relevant subgroups. It broadens the evidence base by incorporating studies in previously under-represented populations and by refining pediatric DGBI categories to align with emerging neurodevelopmental and mechanistic insights.
