Abstract
Obesity is sharply rising worldwide and is increasingly recognized in patients with cirrhosis. This review summarizes the available data documenting a detrimental role of obesity and insulin-resistance on the risk of appearance of clinical events in patients with cirrhosis. Molecular pathways explaining the harmful effect of obesity and insulin resistance in the natural history of cirrhosis are largely unknown. Increasing knowledge of mechanisms leading to white adipose tissue dysfunction on one side, and to portal hypertension on the other side, allow hypothesizing that a link between the pathophysiology of obesity, insulin resistance and portal hypertension in cirrhosis exists. Mechanisms likely involved in this interplay are discussed in this article.
