Story summary

In 2020, experts proposed replacing nonalcoholic fatty liver disease (NAFLD) with metabolic dysfunction-associated steatotic liver disease (MASLD) to emphasize metabolic health and reduce alcohol stigma.
Despite this, NAFLD remains widely used, causing confusion with MASLD and fatty liver disease.
MASLD refers to liver fat accumulation due to metabolic causes, not alcohol.
Metabolic dysfunction can cause insulin resistance, leading to excess free fatty acids in the liver.
Diagnosing MASLD requires confirming liver fat and meeting specific health criteria while excluding significant alcohol use.
