There are different types of liver diseases. One of the most common chronic liver
diseases is Non-alcoholic Fatty Liver Disease (NAFLD). Fatty liver disease is
closely associated with the growing problems of obesity, type 2 diabetes and
metabolic syndrome1. NAFLD does not usually cause any signs or symptoms
but when it does, they may include fatigue, weight loss, yellowing of the skin or
The disease is usually diagnosed on the basis of an abdominal ultrasound or
laboratory tests which reveal elevated levels of hepatic enzymes in some patients
with fatty liver disease3. This disease may lead to irreversible
hepatic cirrhosis which may lead to liver failure and an increased risk of liver
cancer4. Nevertheless, people with fatty liver disease are at an
increased risk of cardiovascular disease1.
Many methods are used in the treatment of this disease: a weight-reduction diet with
particular indication of the Mediterranean diet, increasing physical activity,
pharmacological treatment and surgical treatment of obesity5.
