Detaljerad beskrivning
Functional constipation is common in children and has been associated with gut microbiota dysbiosis and impaired short-chain fatty acid production. Synbiotics combining prebiotics and probiotics may improve stool characteristics and intestinal fermentation.
This study investigated whether daily supplementation with PHGG (4.3 g) plus LGG (1×10⁹ CFU) for 12 weeks improves stool frequency, consistency, gastrointestinal symptoms, and microbiota composition compared with standard dietary advice alone. Whole-genome shotgun metagenomics was performed in a subset of participants to characterize microbial and functional changes.
This study was registered retrospectively on ClinicalTrials.gov because it was initiated as an investigator-initiated academic study without initial intent for regulatory submission. Registration was completed after study completion to ensure transparency and compliance with journal and international reporting standards.
