Abstract

Non-alcoholic fatty liver disease (NAFLD) is the common chronic disease, associated with obesity, especially abdominal obesity, and a metabolic syndrome, that considerably raises cardiometabolic risk and is reflected in morbidity, prognosis of the disease and life expectancy of patients. NAFLD at the stage of steatosis does not increase the risk of mortality in the general population, however, the potentially dangerous stage, non-alcoholic steatohepatitis, in many cases remains unrecognized in a timely manner and, in the absence of adequate treatment, can progress and lead to the development of cirrhosis, liver failure, and hepatocellular carcinoma. The issues of NAFLD treatment are relevant due to the high prevalence of obesity, diabetes mellitus type 2, cardiovascular diseases and their complications. NAFLD therapy should be aimed primarily at the etiopathogenetic factors that contribute to its development and progression, as well as the correction of associated metabolic disorders. The growing prevalence of obesity, NAFLD and associated risk factors, diagnostic difficulties and the lack of an algorithm for managing such patients confirm the urgency of this problem. In this article describes the basic mechanisms of pathogenesis NAFLD, its role in obesity, prognosis of the disease, diagnostics and treatment.
