In general:

Remember the triangle diagram of Dr. Douglas.

• 20% of the population has steatosis, which is fatty infiltration of the liver (reversible process) without elevation of liver enzymes.
• A smaller proportion have steatohepatitis, which is fatty infiltration of liver plus elevation of liver enzymes.
• Some go on to develop fibrosis.
• And some of those go on to develop hepatic failure.

The mainstay of treatment of steatosis and steatohepatitis is control of diabetes, cholesterol; and to continue diet and exercise.  This process is reversible.
