Functional gastrointestinal disorder

Functional gastrointestinal disorders (FGID) include a number of separate idiopathic disorders which affect different parts of the gastrointestinal tract.^[1]

The Rome process has helped to define the functional gastrointestinal disorders.^[2] 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.

• Functional esophageal disorders
  • Functional heartburn
  • Functional chest pain of presumed esophageal origin
  • Functional dysphagia
  • Globus pharyngis

• Functional colonic disease: 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.
  • Functional constipation
  • Functional rectal pain
• Functional dyspepsia
• Noncardiac chest pain
• Chronic functional abdominal pain
• Irritable bowel syndrome

Functional gastrointestinal disorders have been found in 60-70% of both Canadian and American populations.^[1]
