Liver disease has many causes.
Parasites and viruses can infect the liver, causing inflammation and that reduces liver function. The viruses that cause liver damage can be spread through blood or semen, contaminated food or water, or close contact with a person who is infected. The most common types of liver infection are hepatitis viruses, including:
- Hepatitis A
- Hepatitis B
- Hepatitis C
Immune system abnormality
Diseases in which your immune system attacks certain parts of your body (autoimmune) can affect your liver. Examples of autoimmune liver diseases include:
- Autoimmune hepatitis
- Primary biliary cirrhosis
- Primary sclerosing cholangitis
An abnormal gene inherited from one or both of your parents can cause various substances to build up in your liver, resulting in liver damage. Genetic liver diseases include:
- Hyperoxaluria and oxalosis
- Wilson's disease
Cancer and other growths
- Liver cancer
