Non-Alcoholic Fatty Liver Disease (NAFLD)

Summary

NAFLDThis study directly addresses two important health problems, obesity and fatty liver disease, called Non-Alcoholic Fatty Liver Disease (NAFLD). Over 70% of the adult population in the U.S. are overweight or obese as are 20-25% of children and adolescents. Obesity may soon overtake smoking as the leading cause of death in the U.S. About 20% to 30% obese adults in the U.S. have excess fat accumulation in the liver. About 10% of these individuals (2% to 3% of all adults) are estimated to meet current diagnostic criteria for NAFLD. NAFLD can progress to cirrhosis in up to one third of these cases. The incidence of NAFLD increases with an increase in body mass index (BMI). BMI increases in proportion to weight increase. Although NAFLD is the second cause of liver transplantation, weight loss has been shown to improve NAFLD.
