Non-Alcoholic Steatohepatitis (NASH)

Nonalcoholic steatohepatitis (NASH) is liver inflammation caused by a buildup of fat in the liver. The fat buildup is not caused by drinking alcohol.
Many people have a buildup of fat in the liver, and for most people it causes no symptoms and no problems. However, in some people the fat causes inflammation of the liver. Due to the inflammation, the liver doesn’t work as well as it should.
NASH can get worse and cause scarring of the liver, which leads to cirrhosis. But the disease does not always get worse.
There is no clear reason why some people with excess fat in the liver develop NASH and others do not.
