Non-alcoholic fatty liver disease is a condition associated with the accumulation of large amounts of fat in the liver. It can be favoured by a poor diet, but also by various diseases, such as diabetes. The problem with this condition is that it may remain asymptomatic for a long time, but at the same time, irreversible processes may occur in the liver, even resulting in cirrhosis. So how can you tell if a patient is developing non-alcoholic steatohepatitis and how can the disease be treated?
