About Metabolic Dysfunction-Associated Steatohepatitis (MASH)
MASH is the more severe form of metabolic dysfunction-associated steatotic liver disease (MASLD). It is related to the epidemic of obesity, pre-diabetes and diabetes. Unlike liver disease caused by alcohol consumption, MASH is the result of an accumulation of fat in the liver, which can lead to inflammation, cirrhosis and liver-related death.
