Hi, welcome to Healthcaremagic.
What you need to know is that Cirrhosis is most commonly caused by alcoholism,
hepatitis B and C, and fatty liver disease, but theses are not the only causes, there is a multitude of causes. Some cases are idiopathic, i.e., of unknown cause.
You can look into these other causes, if he fits in any :
*Fat that accumulates in the liver (nonalcoholic fatty liver disease)- in fat people
* Iron buildup in the body (
hemochromatosis)
*Too much copper accumulated in the liver (Wilson's disease)
*Liver disease caused by his body's immune system (
autoimmune hepatitis)
*Heart problems- Repeated episodes of
heart failure with liver congestion can lead to cirrhosis.
*Parasite [in developing countries (
schistosomiasis)]
Now the treatment will depend on the cause for the cirrhosis, also the complications of cirrhosis must be treated.
