**3. How does bariatric surgery help NAFLD?**


As a result of insulin resistance, lipolysis occurs in the adipose tissue with increased levels of plasma FFA and excessive influx of FFA into the hepatocytes. In the hepatocytes, fatty acid oxidation is inhibited, and de novo synthesis of fatty acid occurs leading to triglyceride synthesis and hepatic steatosis.

Bariatric surgery reduces insulin resistance by decreasing production of proinflammatory cytokines and improving the adiponectin level.
