Liver disorder or disease (also called as hepatic disease) is a type of damage to or disease of the liver only. The symptoms related to liver dysfunction include both physical signs and a variety of symptoms related to digestive problems, blood sugar problems, immune disorders, abnormal absorption of fats, and metabolism problems. There are many kinds of liver diseases. The most widely spread are:
Hepatitis is inflammation of the liver and is caused mainly by various viruses, bacteria, liver toxins (like alcohol), autoimmunity and inherited disorders. Viral hepatitis is relatively common and can be caused by Cytomegalo Virus (CMV), Epstein-Barr Virus (EBV), Human Immunodeficiency Virus (HIV) and Hepatitis Virus A, B, C, D and E. Of these A, B and C are the most common.
Alcoholic Liver Disease
As the name suggests alcoholic liver disease occurs due to alcohol overconsumption, including fatty liver disease, alcoholic hepatitis, and cirrhosis. The range of disorders can also be caused by various drugs and environmental chemicals and are referred as drug-induced or toxic liver disease.
Fatty Liver Disease
As the name suggests fatty liver disease is due to fat accumulation in liver cells. Non-alcoholic fatty liver disease is associated with obesity and metabolic syndrome. Fatty liver may lead to inflammatory disease and eventually to cirrhosis. Cirrhosis is the formation of fibrous tissue in the place of liver cells that have died due to a variety of causes. Cirrhosis may lead to chronic liver failure.
Primary Biliary Cirrhosis
Primary biliary cirrhosis (PBC) is a serious autoimmune disease of the bile capillaries that is characterized by a slow, progressive destruction of the bile ducts within the liver leading to reduced flow of bile, fibrosis, cirrhosis and eventual liver failure.
Primary Liver Cancer
Primary liver cancer includes hepatocellular carcinoma and / or Cholangiocarcinoma. Rarer forms include Angiosarcoma and Hemangiosarcoma of the liver. Many liver malignancies are secondary lesions that have metastasized from primary cancers in the gastrointestinal tract and other organs, such as the kidneys, lungs, breast or prostate.
