Gut Microbiota World Watch is a new online platform aimed at increasing knowledge and understanding of gut microbiota and its importance for health and quality of life. The intestines are populated with a universe of lifeforms called gut microbiota that perform a variety of vital functions, including functioning as part of the immune system. Launched by the Gut Microbiota and Health section of the European Society of Neurologastroenterology and Motility, this public information service will provide the latest news about gut microbiota. It will act as a point of reference for gut microbiota issues and offer information in straight-forward and easy to understand language. The composition of gut microbita is unique to each individual and evolves throughout the entire life. It is affected by external factors, including conditions of birth, diet, environment, or use of antibiotics. The information service can be accessed at gutmicrobiowatch.org.
