Unmet needs of metabolic dysfunction – Associated “fatty or steatotic” liver disease

Nonalcoholic fatty liver disease (NAFLD), first named in 1980, is currently the most common chronic liver disease, imposing significant health, social, and economic burdens. However, it is defined as a diagnosis of exclusion, lacking a clear underlying cause in its diagnostic criteria. In 2020, meta...

Description
Summary:Nonalcoholic fatty liver disease (NAFLD), first named in 1980, is currently the most common chronic liver disease, imposing significant health, social, and economic burdens. However, it is defined as a diagnosis of exclusion, lacking a clear underlying cause in its diagnostic criteria. In 2020, metabolic dysfunction-associated fatty liver disease (MAFLD) was proposed as a replacement for NAFLD, introducing additional criteria related to metabolic dysfunction. In 2023, metabolic dysfunction-associated steatotic liver disease (MASLD) was suggested to replace NAFLD, aiming to avoid the stigmatizing term “fatty” and incorporating cardiometabolic criteria for metabolic dysfunction. This divergence in nomenclature and diagnostic criteria between MAFLD and MASLD presents challenges to medical communication and progress. This review outlines the pros and cons of both terminologies, based on current research evidence, in the hope of fostering global consensus in the future.
