Non-alcoholic fatty liver disease (NAFLD) affects about one in three US adults, making it the most common chronic liver problem in America. NAFLD develops because of a buildup of fat in the liver. NAFLD can progress into a more serious condition called non-alcoholic steatohepatitis (NASH). Currently, about 5% of American adults have NASH. This condition leads to scarring (cirrhosis), which prevents healthy liver function and increases your risk of liver cancer. There are no medical treatments that can cure fatty liver disease, although there are medications that can help you manage the condition. Making lifestyle changes is the best way to reverse fatty liver disease, such as losing weight, switching to a healthy diet, limiting salt and sugar intake, and increasing physical activity.
