Core Tip

Core tip: Current nonalcoholic fatty liver disease (NAFLD) management is rapidly evolving, and new pathophysiology-based therapies are expected to be introduced in the near future. All NAFLD patients should be evaluated using a three-focused approach that considers risks of liver disease, diabetes and cardiovascular events. The final recommendations of this consensus support the indication of lifestyle changes, including diet and exercise, for all patients with NAFLD. Proven pharmacological therapies only consider vitamin E and pioglitazone, which can be used in nondiabetic patients with biopsy-proven nonalcoholic steatohepatitis (the progressive form of NAFLD), although the long-term safety and efficacy of these therapies have not been established.
