[ Summary ] |
Obesity can lead to nonalcoholic fatty liver disease (NAFLD). The global prevalence of NAFLD was reported to be around 25 % in a meta‒analysis of over 8 million individuals. It has become a huge global health burden. NAFLD consists of two clinical entities: nonalcoholic fatty liver (NAFL), which is mostly benign, and nonalcoholic steatohepatitis (NASH), which is a progressive form, diagnosed based on histology of the steatohepatitis, that may lead to cirrhosis or even hepatocellular carcinoma. NASH accounts for 10 %‒20 % of NAFLD cases. Fibrosis is a key risk factor for prognosis. NAFLD is increasingly emerging as a cause of cirrhosis or hepatocellular carcinoma. Currently, weight reduction is the only promising treatment for NAFLD, but new treatments are being aggressively investigated globally. |
