Metabolic Muddle. MASLD and MASH on the Horizon.

Abstract

NAFLD (non-alcoholic fatty liver disease) and NASH (non-alcoholic steatohepatitis) are time-honored acronyms, with widely popular acceptance. Experts now recommend discarding them in favor of MASLD for "metabolic dysfunction-associated steatotic liver disease" and MASH for "metabolic dysfunction-associated steatohepatitis." The reasons for this change are explored and an argument about why the change is confusing, is advanced. Should these acronyms become clinically popular, risk assessment manuals will require updates.
