Purpose of review: Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder (FGID) encountered by the pediatrician and consultant. The primary focus of this review is to provide an update on beneficial nutritional interventions for managing this patient population with discussion on gut microbiome effects.
Recent findings: A common complaint among the pediatric population is IBS-related recurrent abdominal pain. The prevalence of IBS is estimated to range between 6 and 14% and is defined by the Rome III criteria for FGIDs. Recent studies highlight the role of nutritional interventions in mitigating symptoms of IBS. Although eliminating foods that aggravate IBS gastrointestinal symptoms have become a main nutritional approach for acute management of IBS, recent literature reflects how this may impact the gut microbiome and potentially have long-term implications.
Summary: There are emerging studies suggesting IBS symptomatic improvement with different dietary interventions in the pediatric population, but most of what is known at this time has been extrapolated from the adult literature.
