MASH stands for metabolic dysfunction-associated steatohepatitis (MASH) (formally known as nonalcoholic steatohepatitis) and is the more serious form of MASLD (formally known as non-alcoholic fatty liver disease). MASH affects almost 1.5 million Canadians, even those who drink little or no alcohol. Not only can MASH cause liver scarring, called fibrosis, but about 1 out of 5 adults with MASH can develop potential damage to liver function called cirrhosis.
