-Diagnosing fatty liver disease may be challenging since it commonly presents itself without any symptoms. Fatty liver disease is suspected when liver enzymes are elevated and/or when your liver looks unusual on ultrasound, however other liver disease must be ruled out first. The main complication associated with fatty liver disease is fibrosis and cirrhosis, which is caused by the scarring that occurs with chronic inflammation. In some cases you will need a liver biopsy to confirm the diagnosis, and to check how bad the liver damage is.
What are the treatments for Fatty Liver Disease?
-To reduce your risks of nonalcoholic fatty liver disease, choose a healthy diet, maintain a healthy weight and exercise regularly. This can reduce the amount of inflammation and reverse the process of fat accumulation in the liver. Certain medications that are known to cause fatty liver disease may have to be stopped or switched. For patients who suffer from alcoholic liver disease, its very important that they stop drinking alcohol. Any patient with fatty liver disease should get vaccinated for hepatitis A and B since getting either with a fatty liver is more likely to lead to liver failure.
Both alcoholic and nonalcoholic fatty liver disease have the potential to lead to cirrhosis. For patients who have cirrhosis, aggressive medical management and/or a liver transplantation may be an option.
