Hi how has everything been since you posted this i am newly diagnosed.
Hello and hope you are doing well.
Fatty liver can be due to alcoholism when it is called Alcoholic fatty liver disease and the other one is Non alcoholic fatty liver disease, which is due to obesity, diabetes and high triglyceride levels. This can progress to cirrhosis of the liver and can be associated with hepatocellular carcinoma. So, prevention or cure is by avoiding alcohol and treating diabetes, obesity and high triglyceride levels.
You could follow certain other precautions. Avoid smoking and drugs. Avoid medications like paracetomol and sedatives. Get vaccinated for hepatitis A and B and take a good protein diet.
Hope this helped and do keep us posted.
