FGIDs are associated with substantial impairments in quality of life, frequent school absences, and high levels of psychological comorbidity, contributing to a considerable burden for families and healthcare systems. Despite their high prevalence, the pathophysiology remains incompletely understood, with evidence pointing to a multifactorial interplay of biological, psychological, and environmental factors. Given their frequency across healthcare settings and their significant psychosocial and economic impact, a better characterization of FGIDs in real-world pediatric populations is needed. This retrospective chart review aimed to examine patterns of FGIDs and their associations with gender, temporal factors, geographic setting, and hospitalization burden in a Swiss pediatric cohort within a biopsychosocial framework. Methods: This retrospective chart review study included 1445 patients aged 0\u201318 years. Patients were selected based on having received an ICD-10 diagnosis attributed to FGID. The frequency and distribution of the aforementioned factors were determined, as well as their associations with each other. Results: A male predominance of FGIDs in newborns (p &lt; 0.001), a female predominance in adolescents (p &lt; 0.001), and sex-based differences in subtype distribution (p &lt; 0.001) was found in this cohort of patients. A higher proportion of FGID cases were found among children in urban areas than in rural and suburban areas. Infants were hospitalized for significantly longer periods on average than older children and males were hospitalized for longer periods on average than females. Discussion and Conclusions: These findings highlight the importance of early, integrated, interdisciplinary care pathways. Given the growing mental health issues affecting adolescent girls and the well-documented bidirectional relationship between emotional stress and FGID symptoms, it is suggested that early psychological screening and family-based interventions could reduce the chronicity of symptoms, prevent unnecessary hospitalizations and improve long-term health outcomes.<\/jats:p>","DOI":"10.3390\/children13070885","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T03:06:34Z","timestamp":1782875194000},"page":"885","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the Organic: A Biopsychosocial Analysis of Pediatric Functional Gastrointestinal Disorders\u2014A Retrospective Chart Review"],"prefix":"10.3390","volume":"13","author":[{"given":"Julia","family":"Greuter","sequence":"first","affiliation":[{"name":"Faculty of Medicine, University of Basel, 4056 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9273-5845","authenticated-orcid":false,"given":"Margarete","family":"Bolten","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Basel, 4056 Basel, Switzerland"},{"name":"Switzerland Luzerner Psychiatrie AG Child & Adolescent Psychiatry, Children\u2019s Hospital Central Switzerland (KidZ), 6004 Lucerne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corinne","family":"L\u00e9geret","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, University Children\u2019s Hospital of Basel, 4056 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101","DOI":"10.14218\/JTG.2023.00075","article-title":"Pediatric Functional Gastrointestinal Disorders: Pathophysiology, Diagnosis and Management","volume":"2","author":"Mahesan","year":"2024","journal-title":"J.
