There is more than one type of liver disease, states MedlinePlus. Liver diseases include various forms of hepatitis, hereditary diseases such as hemochromatosis and malignant tumors.
Some liver diseases are inherited, such as hemochromatosis and Wilson's disease, according to Mayo Clinic. Other liver diseases include autoimmune diseases. This is when the body's immune defenses attack the liver or any other organ as if it's a foreign body. Primary biliary cirrhosis may be one such disease, according to MedicineNet.
Hepatitis is a common liver disease, states WebMD. Some forms of hepatitis are caused by a virus, though hepatitis means any inflammation of the liver. Many people are familiar with the viral type of hepatitis. These types of hepatitis are designated as A,B,C,D and E. However, other viruses can cause hepatitis, and it can also be caused by alcoholism, too much fat in the liver and toxins. Hepatitis can even be a result of an autoimmune disease.
Hemochromatosis is a liver disease where the body stores so much iron in the liver that the organ can become damaged, according to Mayo Clinic. This genetic disease is the most common found in Caucasians. Most people are asymptomatic, and the easiest treatment for it is to donate blood.
