In medicine, the term functional colonic disease (or functional bowel disorder) refers to a group of bowel disorders which are characterised by chronic abdominal complaints without a structural or biochemical cause that could explain symptoms.
The Rome process has helped to define the functional gastrointestinal disorders.1 Successively, the Rome I, Rome II and the Rome III meetings have proposed a consensual classification system and terminology, as recommended by the Rome Coordinating Committee.
