The aim of this study was to review the existing literature on abdominal pain in children and adolescents with autism spectrum disorder. Systematic search of four databases (PsycINFO, ERIC, PubMed, MEDLINE) identified 13 studies that met the inclusion criteria. Articles were analyzed for common themes, including the prevalence of abdominal pain and gastrointestinal (GI) symptoms, associations between abdominal pain/GI symptoms and behavioral and emotional concerns, associations between abdominal pain/GI symptoms, and other comorbid disorders and treatment options based on gut bacteria, diet, and probiotics. Reasons for varying prevalence rates, persistence of symptoms over time, comorbidities, and different treatment options are discussed. Clinical implications and recommendations for future research are also discussed.
