Gut dysbiosis, characterized by reduced bacterial diversity and butyrate production, contributes to the pathogenesis of liver diseases (NAFLD, NASH, Alcoholic Liver Disease, PSC) through the translocation of bacterial products (endotoxins) to the liver, triggering inflammation.

Maintaining gut barrier integrity and microbial diversity is crucial for liver health. Probiotics and dietary fiber may help reduce liver inflammation by preventing the translocation of bacterial endotoxins to the liver.

GoodSupportsHIGH confidence
The liver receives 70% of its blood supply from the intestine via the portal vein, thus it is continually exposed to gut-derived factors including bacterial components, endotoxins... Patients with NAFLD also have increased gut permeability suggesting that translocation of bacteria or microbe derived products into the portal circulation contributes to the pathogenesis.
