[Research status and prospects of probiotics in functional gastrointestinal disorders in infants and toddlers].

Functional gastrointestinal disorders (FGIDs) are common digestive system diseases in children, which can severely affect the growth and development of infants and toddlers. Probiotics therapy, as a relatively safe treatment method, have attracted the attention of researchers. However, their effectiveness in treating FGIDs in infants and toddlers is still unclear. This article reviews the mechanisms of probiotics in treating FGIDs in infants and toddlers, explores the reasons for the inconsistency in various research results, and aims to provide assistance for the clinical treatment of FGIDs in infants and toddlers and future research.
