This study aims to equip health professionals with essential directions for their practice and research in fatty liver disease. In fatty liver disease, excess fat is accumulated in the liver cells, and it mainly has two types: Alcoholic Fatty Liver Disease (AFLD) and Non-Alcoholic Fatty Liver Disease (NAFLD). AFLD is widely accepted to be associated with excessive alcohol consumption. However, in NAFLD's case, although the name acknowledges that it is not associated with excessive alcohol consumption, the exact cause of NAFLD remains ambiguous. Furthermore, for almost four decades, without specialised treatments and prevention strategies, NAFLD has constantly increased, affecting more than a quarter of the world's population.
