Metabolic indicators and zonulin levels were similar, except for urea, which was significantly higher in the malabsorption group (31.7±6.3 mg/dL) compared to those without fructose malabsorption (24.5±÷7.8 md/dL; P=0.012).</p><p><strong>Conclusion: </strong>Intestinal fructose malabsorption is common in asymptomatic adolescents and is not associated with adiposity, biochemical changes, or increased intestinal permeability. However, it correlates with elevated fermentation in the lactulose breath test. Fructose intolerance is linked to presence gastrointestinal symptoms following lactulose ingestion.</p>","PeriodicalId":35671,"journal":{"name":"Arquivos de Gastroenterologia","volume":"63 ","pages":"e25078"},"PeriodicalIF":0.0,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13200566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
