Recent studies have pointed out the role a dysbiosis in gut microbiota plays in the onset and progression of liver disease. Chronic alcohol consumption is known to be a major disruptor of the microbial community harboured in the intestines and can both cause bacterial alteration, increasing the proportion of harmful bacteria and reducing levels of beneficial bacteria; and also it can provoke an overgrowth of microorganisms, which is associated with liver disease.

Bernd Schnabl is an Associate Professor in Gastroenterology at University of California San Diego School of Medicine, where he investigates precisely the pathogenesis of chronic liver disease. He attended the 5th Gut Microbiota for Health World Summit 2016.
