Core Tip

Core tip: Given the increasing prevalence of the disease, Nonalcoholic fatty liver disease (NAFLD), adequate knowledge regarding the disease is becoming especially important for physicians and patients. Despite this, since its description in 1981 in pregnant women, NAFLD has been a difficult to understand and treat for both scientists and clinicians. Current efforts to elucidate the mechanism and causes of the disease have answered some questions, but much remains unknown about NAFLD. The aim of this article is to discuss the current knowledge regarding the pathogenesis of the disease, as well as the current and future diagnostic, preventative, and therapeutic options available to clinicians for the management of NAFLD.
