What is fatty liver?

Fatty liver is a life style disorder affecting millions of people in Kerala. It is a reversible condition wherein fat accumulate in liver cells leading to enlargement of liver, inflammation and liver cell destruction. Two common causes for fatty liver are alcohol intake and non- alcoholic fatty liver disease or NAFLD. NAFLD is a disorder of fat metabolism wherein the fat can accumulate in the liver in excessive amounts, thus resulting in a fatty liver.

NAFLD can progress to more serious disease stages, such as advanced fibrosis, cirrhosis, liver failure or liver cancer.
