ESPGHAN/NASPGHAN guidelines for treatment of irritable bowel syndrome and functional abdominal pain-not otherwise specified in children aged 4-18 years

Abdominal pain related disorders of gut-brain interaction (AP-DGBIs) such as irritable bowel syndrome (IBS) and functional abdominal pain-not otherwise specified (FAP) are common conditions in children, significantly impacting quality of life. This treatment guideline for IBS and FAP in children of 4-18 years is a collaborative effort of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN and NASPGHAN). We aim to comprehensively review the current evidence on treatment options and offer evidence-based recommendations with utility across all treatment settings worldwide, as well as to provide methodological directions for future research.
