Core Tip
Core tip: Epidemiological studies on functional gastrointestinal disorders in children and adolescents provide variable prevalence rates in both non-clinical and clinical settings. The scarcity of good quality prevalence data for functional gastrointestinal disorders in light of recent Rome IV criteria reveals an urgent need for more trustworthy information to construct evidence-based health policy. The current literature review suggested higher impact of cyclic vomiting, irritable bowel syndrome and functional constipation in children and adolescents.
