That figure is an estimate based on findings from a San Diego study published in Pediatrics.
Nonalcoholic fatty liver disease is fat in the liver without liver inflammation and liver damage.
It can worsen into nonalcoholic steatohepatitis (NASH), which is fatty liver with liver inflammation and liver damage.
NASH can eventually cause permanent liver scarring (cirrhosis) and may even require a liver transplant.
In short, fat in the liver can be a slippery slope toward serious liver problems."
