Non-alcoholic fatty liver disease: A poorly known pandemic

Non-alcoholic fatty liver disease (NAFLD) consists of an excessive depositing of fat in the liver, which can end up by causing inflammation, fibrosis and also cirrhosis with the corresponding complications including liver cancer. NAFLD has become the most common liver disease worldwide. The incidence has increased in parallel with the obesity, diabetes and metabolic syndrome epidemic, thus resulting in becoming one of the main indications for liver transplant. The diagnosis has principally been through histology but with the development of non-invasive methods, these have helped in simplifying the management of these patients in clinical practice. The only therapeutic strategies currently available are focused on weight loss (lifestyle changes or bariatric surgery). There is still no approved pharmacological option for the treatment of NAFLD, however there are a number of molecular studies in advanced stages of development.
