Hello, Although alcohol consumption is the most common cause for liver cirrhosis but in absence of alcoholism,other most important causes are viral hepatitis B,C and D. Hepatitis A doesnt result in cirrhosis and HEPATITIS D is very rare. There is no cure for liver cirrhosis although medications are given which tend to delay the progression of cirrhosis and reduce the liver injury. Treatment for viral hepatitis induced is done by steroids and anti viral drugs. The ultimate treatment,however is liver transplant only. Her diabetes should be monitored and treated properly. Thanks
