Chronic intermittent hypoxia exacerbates hepatic steatosis in a microbiota-dependent manner in lean mice

and elevation of deoxycholic acid were linked to CIH-induced hepatic phenotypes and were sensitive to antibiotic intervention, supporting a contributory role of gut microbiota-bile acid interactions in this process. Together, these findings underscore the potential importance of gut microbiota-host metabolic crosstalk in OSA-associated hepatic steatosis and suggest that microbiota- or bile acid-targeted strategies may warrant further investigation as adjunctive approaches for risk stratification and therapeutic intervention in OSA-related liver disease.
