World Gastroenterology Organisation Announces the Release of an Updated Global Guideline

Milwaukee, WI, USA, 13 April 2017.  The World Gastroenterology Organisation (WGO) has announced the release of the newly updated “Probiotics and prebiotics” Guideline.

About This Guideline
The recently updated Probiotics and prebiotics Guideline, chaired by Professor Francisco Guarner, University Hospital Vall d'Hebron (Barcelona, Spain) will be of interest to all health professionals in primary and secondary care in different countries of the world.  “We want to transmit to health professionals worldwide relevant knowledge of the use of probiotics or prebiotics to influence the gut environment for the benefit of human health.  During the last six years (2011-2017), an enormous amount of new evidence on the use of probiotics and prebiotics in practice has been published,” noted Professor Guarner, Chair of the Guideline, on why there was a need to update the guideline.

The updated Probiotics and prebiotics Guideline was created by a global Review Team including: Francisco Guarner (Chair, Spain), Mary Ellen Sanders (Co-Chair, USA), Rami Eliakim (Israel), Richard Fedorak (Canada), Alfred Gangl (Austria), James Garisch (South Africa), Pedro Kaufmann (Uruguay), Tarkan Karakan (Turkey), Aamir G. Khan (Pakistan), Nayoung Kim (South Korea), Juan Andrés De Paula (Argentina), Balakrishnan Ramakrishna (India), Fergus Shanahan (Ireland), Hania Szajewska (Poland), Alan Thomson (Canada) and Anton Le Mair (The Netherlands), as well as invited experts Dan Merenstein (USA) and Seppo Salminen (Finland).  The guideline and can be accessed at

WGO currently has a library of over 20 Global Guidelines and Cascades, which are written from a viewpoint of global applicability. Each Guideline goes through a rigorous process of authoring, editing, and peer review, and is as evidence based as possible. WGO is the only organization whose guidelines have adopted a global focus. Many WGO Guidelines are Cascade-based, which offers different options for diagnosis and treatment of the same disease depending on available resources. A Cascade is a hierarchical set of diagnostic, therapeutic, and management techniques for dealing with risk and disease, ranked according to the resources available. Each WGO guideline is available in English, Spanish, Portuguese, French, Mandarin, and Russian, and is updated as new information and evidence is discovered. The Global Guidelines Committee meets each year to discuss updating and creating new guidelines and consists of 30-plus members from around the globe.
