The World Gastroenterology Organization (WGO) recently released an updated guideline document, aimed at helping gastroenterologists and other physicians understand the appropriate clinical applications of probiotics or prebiotics. The guideline was created with input from experts in gastroenterology, probiotics and prebiotics, with efforts co-led by experts from the International Scientific Association for Probiotics and Prebiotics (ISAPP). To create these guidelines, experts comprehensively evaluated the evidence from randomized, controlled trials for gastrointestinal conditions, including which specific prebiotic strain or substance showed a positive effect. The guidelines present a list of conditions for which there is positive evidence for the effectiveness of probiotics and/or prebiotics.
