Abstract

Pediatric gastroenterology addresses a wide spectrum of gastrointestinal (GI), hepatic, and nutritional disorders
in infants, children, and adolescents. Conditions such as gastroesophageal reflux disease (GERD), celiac disease,
inflammatory bowel disease (IBD), and functional abdominal pain are increasingly recognized in pediatric populations.
This article outlines the pathophysiology, diagnostic strategies, and evidence-based treatments for major pediatric
gastrointestinal disorders. It emphasizes the role of endoscopy, dietary interventions, microbiome research, and
multidisciplinary management approaches in improving outcomes and quality of life for affected children.
