title: Metabolic syndrome and non-alcoholic fatty liver disease.
abstract: The development of nonalcoholic fatty liver disease (NAFLD) is strongly associated with the metabolic syndrome as reflected by the fact that approximately 90% of the patients with NAFLD have more than one feature of metabolic syndrome and about 33% have three or more criteria. The physiopathology, epidemiology and therapeutic considerations of the disease are reviewed here. Lipotoxicity plays a predominant role in the pathophysiology of both entities. It leads to accumulation of triglycerides in the liver as a result of an imbalance among the uptake, synthesis, export, and oxidation of fatty acids. Both conditions are very common in Mexico. Using the Adult Treatment Panel diagnostic criteria, the 1994 prevalence of the metabolic syndrome was 26.6%.Although the prevalence of NAFLD is not known, but it can be estimated from the prevalence of obesity (30%). Since NAFLD is found in over two thirds of the obese subjects, this condition may exist in 20% of the adult population. The treatment of both conditions should be based in an integral approach, including the adoption of a healthy lifestyle, weight loss and may be pharmacotherapy. In summary, NAFLD is the hepatic expression of the metabolic syndrome. The study and treatment of these disorders could not be viewed as separate issues.
