Nonalcoholic fatty liver disease (NAFLD) is not an unheard term anymore. Over the past 2 decades, it has grown from a relatively unknown disease to the most common cause of chronic liver disease in the world. In fact, 25% of the world’s population is currently thought to have NAFLD. Surprising is that it is highly prevalent in children as well. The worldwide prevalence of NAFLD in children is a worrying phenomenon because this disease is closely associated with the development of both cirrhosis and cardiometabolic syndrome in adulthood. Nonalcoholic steatohepatitis, a progressive form of NAFLD is one of the most common hepatic diseases in children who present with particular risk factors including obesity, sedentary lifestyle, and/or a predisposing genetic background.
