What is fatty liver disease?

Nonalcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease in the United States, affecting about one-quarter of the population.

If left untreated, it may progress into nonalcoholic steatohepatitis (NASH), an aggressive form of fatty liver disease, which is marked by liver inflammation and may progress to advanced scarring (cirrhosis) and liver failure.

Nonalcoholic Fatty Liver Disease (NAFLD)

A condition in which excess fat is stored in your liver.

Nonalcoholic Steatohepatitis (NASH)

A more severe form of NAFLD in which the buildup of fat in the liver causes inflammation and cell damage.

Healthy Liver

The liver is very resilient and capable of regenerating itself. If not taken care of, after many years it will reduce its ability to regenerate.

Infographic of NAFLD


NAFLD is more common in people who have certain conditions, including obesity, type 2 diabetes, and metabolic syndrome.

Infographic of NASH


Often NAFLD and NASH cause few or no symptoms. Certain health conditions—including obesity, metabolic syndrome, and type 2 diabetes— make you more likely to develop NAFLD and NASH.

Cirrhosis is a late stage of scarring (fibrosis) of the liver. Severe scarring has built up, making it difficult for the liver to function properly.
