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.
Over the last 17 years, 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.
