Fatty Liver is not a disease but what it can lead to if left untreated. the following information is from a Doctor at Columbia university on the subject.
Some individuals can develop fatty liver. Most people who do not abuse alcohol and have fatty liver are obese. Fatty liver is called steatosis, and fatty liver with liver inflammation is called or steatohepatitis.
Steatosis and steatohepatitis can be caused by alcohol and other drugs and can also sometimes occur in patients with diabetes mellitus. The factors that determine who will develop fatty liver are not known. Some mildly obese and occasional non-obese patients will develop fatty liver while some who are severely obese will not. Patients with fatty liver or steatohepatitis usually present to a physician with unexplained elevations in the serum aminotransferase activities. Serum alkaline phosphatase and gamma-glutamyltranspeptidase activities are usually normal. The patient is usually 10% or more above
his/her ideal body weight.The diagnosis is usually suspected after other causes of hepatitis are excluded.
A careful drug and alcohol history should be taken and serological testing for HBsAg and antibodies
against the hepatitis C virus should be performed. Metabolic diseases should be excluded by a careful family history and appropriate testing if they are suspected. Serum protein electrophoresis and testing for
autoantibodies should be performed if autoimmune hepatitis is suspected. Sometimes, patients with fatty liver or steatohepatitis will have elevated serum trigyceride concentrations, however, this is not always the case.
If a patient has elevations in serum aminotransferase activities for longer than six months, he/she should have a liver biopsy to make the diagnosis the fatty liver or steatohepatitis. Steatohepatitis can progress to cirrhosis. Treatment (diet and exercise) may stop this progression. Steatosis and steatohepatitis will often improve with weight loss, preferably to near the patient's ideal body weight. Avoidance of alcohol and potentially hepatotoxic drugs may also be beneficial.
