Core Tip

Core Tip: The transition from non-alcoholic fatty liver disease to metabolic dysfunction-associated steatotic liver disease refocuses diagnosis on metabolic dysfunction, capturing a broader spectrum of patients with type 2 diabetes mellitus and hepatic steatosis. Metabolic dysfunction-associated steatotic liver disease and its related category, metabolic and alcohol-associated liver disease, improve disease recognition, prevalence estimation, and management strategies compared to non-alcoholic fatty liver disease. This minireview highlights the clinical implications of these changes, including the need for reclassification in trials, metabolic-targeted treatments, and multidisciplinary approaches to enhance screening and outcomes in type 2 diabetes mellitus populations.
