The etiology of cirrhosis includes the following eight aspects:
(1): the most common hepatitis virus of hepatitis B virus, hepatitis C virus and hepatitis B virus infection. Hepatitis B virus infection in some patients with chronic hepatitis, and chronic hepatitis B and a small part of the development of cirrhosis. About half of all patients with acute hepatitis C develop chronic hepatitis, of which 10% to 30% will develop cirrhosis. Hepatitis D virus on hepatitis B virus hepatitis can occur, some patients develop cirrhosis.
(2) alcohol: chronic alcohol consumption leads to liver cell damage, fatty degeneration, necrosis and fibrosis.
(3) cholestasis: chronic cholestasis, leading to liver cell inflammation and ductular reaction, even necrosis, the formation of biliary cirrhosis.
(4) congestion factors: chronic heart function insufficiency, repeated constrictive pericarditis and hepatic venous obstruction can cause liver congestion, the liver cells to hypoxia and necrosis, degeneration, eventually lead to liver cirrhosis. Cardiac cirrhosis due to cardiac cirrhosis.
(5) drug or chemical poison factors: long-term use of certain drugs, such as bisatin, Xin Kefen, methyldopa can lead to drug-induced hepatitis, finally develop cirrhosis. Long term exposure to certain chemicals, such as carbon tetrachloride, arsenic, phosphorus and other toxic hepatitis, can develop into cirrhosis.
(6) metabolic disorder: disorder of copper metabolism, seen in hepatolenticular degeneration. Iron metabolism in hemophilia, galactosemia, cystic fibrosis, alpha antitrypsin deficiency, glycogen storage disease, tyrosinosis, hereditary hemorrhagic telangiectasia, or associated with genetic metabolic defects, can lead to cirrhosis of the liver.
(7) parasitic infection: schistosomiasis infection is more common in the south of China, which can lead to schistosomiasis, and further lead to liver fibrosis and cirrhosis. Human infection of Clonorchis sinensis after not timely treatment can cause cirrhosis.
(8) other factors: a high degree of malnutrition can lead to cirrhosis of the liver, and a small part of the liver cirrhosis is unknown.
