NAFLD renaming to MAFLD, MASLD: background, similarities, differences, and countermeasures

Abstract

Nonalcoholic fatty liver disease (NAFLD) is a chronic metabolic stress liver injury due to chronic malnutrition in genetically susceptible individuals. With the prevalence of obesity, diabetes, and metabolic syndrome, NAFLD has become the world's number one chronic liver disease, and the flaws of forty years of exclusive disease diagnostic criteria and stigmatized disease terminology are becoming increasingly prominent. To this end, in the past three years, the international consensus group and the three major hepatology societies have suggested that NAFLD be renamed metabolism-associated fatty liver disease (MAFLD) and metabolism-associated steatosis liver disease (MASLD). Here is a description of the background of naming NAFLD, MAFLD, and MASLD, the similarities and differences of the three terms, the existing disputes, and our country's coping strategies.
