The Rome Foundation is an independent not for profit 501(c) 3 organization that provides support for activities designed to create scientific data and educational information to assist in the diagnosis and treatment of functional gastrointestinal disorders (FGIDs). Our mission is to improve the lives of people with functional GI disorders.

For over two decades, the Rome organization has sought to legitimize and update our knowledge of the FGIDs. This has been accomplished by bringing together scientists and clinicians from around the world to classify and critically appraise the science of gastrointestinal function and dysfunction. This knowledge permits clinical scientists to make recommendations for diagnosis and treatment that can be applied in research and clinical practice.

The Rome Foundation is committed to the continuous development, legitimization and preservation of the field of FGIDs through science-based activities. We are inclusive and collaborative, patient-centered, innovative and open to new ideas.  (From the Rome Foundation website. Quoted with permission)

International functional GI experts finalized Rome IV, the first major update to the Rome criteria since 2006, in December 2014 in Rome, Italy. Rome IV was published in the journal Gastroenterology in May 2016 and officially presented to the gastroenterology professional community at the Digestive Disease Week conference in San Diego, California, USA on May 21-25, 2016.

The article states that Rome international diagnostic criteria for IBS, based on symptoms, are considered to be 98% accurate. Extensive testing of all people with potential IBS is unnecessary and discouraged, and is usually appropriate only for a few subgroups at higher risk of different GI disorders. Unfortunately studies show that health care providers in local communities are much more likely than IBS/functional GI specialists to still believe erroneously that IBS is a diagnosis of exclusion requiring many tests to rule out other conditions.

There are many conditions that fall along the spectrum of functional gastrointestinal disorders, also known as disorders of gut-brain interaction. Irritable bowel syndrome (IBS) is the most common condition in this category. This large study conducted in the United States, Canada and the United Kingdom  found that approximately a third of adults meet Rome IV criteria for a functional GI disorder, and approximately a third of that subset have two or more functional GI disorders.
