Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH)

Metabolic dysfunction-associated steatotic liver disease (MASLD) happens when your liver stores too much fat and it is not related to heavy alcohol use. Metabolic dysfunction-associated steatohepatitis, or MASH, is a more severe form of fatty liver disease that causes inflammation, called hepatitis, and liver cell damage.
