Hepatic steatosis (fatty liver) is increasingly recognized as a major component of the metabolic (insulin resistance) syndrome. It can progress to cirrhosis and hepatocellular carcinoma, leading to liver-related mortality. Increasing evidence shows a significant association between hepatic steatosis and hypertension; both are linked to the metabolic syndrome. This review discusses the evidence to support this association, and reviews the diagnosis and management of hepatic steatosis.
