Oral bacteria may signal liver disease risk

Research links mouth microbes to gut damage and progression of chronic liver disease

Your mouth bacteria can predict risk of chronic liver disease, says study.

Your mouth bacteria can significantly affect your gut health, and predict the risk of chronic liver disease, finds a study.

Each year, more than two million people die from advanced chronic liver disease (ACLD).

In the study, published in the journal Nature Microbiology, the researchers analysed bacterial populations in saliva and stool samples from 86 patients.

The team from the Technical University of Munich in Germany found that both the gut and oral microbiome undergo significant changes as liver disease worsens, where changes to the oral microbiome were already detectable at earlier disease stages.
