Abstract
As a result of the obesity epidemic, Nonalcoholic fatty liver disease (NAFLD) and its complications have increased among millions of people. Consequently, a group of experts recommended changing the term NAFLD to an inclusive terminology more reflective of the underlying pathogenesis; metabolic-associated fatty liver disease (MAFLD). This new term of MAFLD has its own disease epidemiology and clinical outcomes prompting efforts in studying its differences from NAFLD. This article discusses the rationale behind the nomenclature change, the main differences, and its clinical implications.
Core Tip: A new nomenclature to represent the underlying pathophysiology of fatty liver disease has been created and labeled metabolic-associated fatty liver disease. This article discusses the rationale behind the nomenclature change, the main differences to nonalcoholic fatty liver disease, and its clinical implications.
