Abstract
Chronic abdominal pain is common in children and in the majority of cases is functional in nature. For children with abdominal pain lasting 2 months or longer, the Rome IV criteria should be used to diagnose a functional abdominal pain disorder (FAPD). Recent advances have furthered our understanding of the pathogenesis, evaluation, and management of pediatric FAPDs, but these disorders remain challenging to recognize and treat successfully. Effective management requires an understanding of the many factors that can contribute to an individual child’s presentation. Treatment of an FAPD should be tailored to the individual and can include a combination of pharmacologic, dietary, and psychosocial interventions.
