Abstract: Abdominal bloating/distension is a common symptom and/or sign in clinical pediatric practice，which can be either a subjective sensation of bloating or an objectively measurable distention. Its etiology is various，encompassing functional gastrointestinal disorders，medical organic diseases，and surgical organic diseases. In clinical practice，clinicians must reduce unnecessary examinations related to functional disorders while avoiding missed diagnosis and misdiagnosis of organic diseases.Dysbiosis and translocation of intestinal microbiota also contribute to the development of abdominal bloating/distension.Herein，we propose a standardized diagnostic and treatment strategy for pediatric abdominal bloating/distension and summarize the latest advances to provide references for clinical practice.

Key words: abdominal bloating, intestinal obstruction, functional gastrointestinal disorder, children
