Functional gastrointestinal disorders

Rome IV defines functional gastrointestinal disorders (FGID) as “disorders of gut-brain interaction. It is a group of disorders classified by [gastrointestinal] symptoms related to any combination of the following: motility disturbance, visceral hypersensitivity, altered mucosal and immune function, altered gut microbiota, and altered central nervous system (CNS) processing.” (Drossman. 2016)

Rome IV identifies seven FGID for neonates and toddlers including paediatric irritable bowel syndrome, functional constipation, functional diarrhoea, infant regurgitation, infant colic (Benninga et al. 2016; Drossman. 2016).
