What causes cirrhosis?
Causes of cirrhosis include
heavy alcohol use
some drugs, medicines, and harmful chemicals
infections
chronic hepatitis B, C, or D—viral infections that attack the liver
autoimmune hepatitis, which causes the body’s immune system to destroy liver cells
nonalcoholic fatty liver disease, which is often caused by obesity
diseases that damage or destroy bile ducts—tubes that carry bile from the liver
Some inherited diseases—diseases that are passed from parent to child—can cause cirrhosis:
hemochromatosis, a disease that causes iron to collect in the liver
Wilson disease, a condition that causes copper to build up in the liver
porphyria, a disorder that affects the skin, bone marrow, and liver
