Core Tip

Core Tip: The emerging field of research on the gut microbiome’s role in alcohol use disorder (AUD) has revealed significant implications for health outcomes and potential therapeutic strategies. Alcohol consumption has profound effects on the gut microbiome, leading to dysbiosis and increased systemic inflammation but their association has been found bidirectional. The gut microbiome represents a promising therapeutic target for the treatment of AUD, with dietary interventions such as probiotics and prebiotics, as well as fecal transplantation showing potential in improving gut dysbiosis and reducing inflammation.
