Metabolic dysfunction-associated steatotic liver disease (MASLD) is a condition where there is a buildup of fat in the liver in people with diabetes, obesity, high blood pressure, or high cholesterol and drink little to no alcohol. Up to 30 out of 100 people or over 100 million of American adults have MASLD. Obesity is thought to be the most common cause of fatty infiltration of the liver. Some experts estimate that about two thirds of obese adults and half of obese children may have fatty liver. About 2 to 5 percent of adult Americans and up to 20 percent of those who are obese may suffer from the more severe condition metabolic dysfunction-associated steatohepatitis (MASH- the advanced stage of MASLD).
