Diseases of the liver

Viral Hepatitis

Virus infections are the commonest causes of acute liver injury. It includes Type A, Type B and Type C. Type A virus spread through food, water and contaminated faeces. Type B & C viruses spread by blood and blood products, body fluids such as saliva, semen, vaginal secretions and from mother to fetus. Type B virus causes massive liver necrosis and death. Intravenous drug addicts and male homosexuals are at a greater risk.

Cirrhosis

This is inflammation of liver due to alcohol abuse, hepatitis B & C virus infections etc. The liver tissue that is destroyed is replaced by fibrous tissue, leading to liver failure.

Jaundice

This is not a disease but a symptom of liver disorder. It is due to abnormal bilirubin metabolism and excretion. There is an obstruction in the flow of bile from the liver to the duodenum, resulting in bilirubin accumulation giving rise to the yellow colouration of skin and conjunctiva.
