Hepatitis In hemochromatosis, excess amounts of iron accumulate in multiple body sites, including the liver, which can lead to cirrhosis. In Wilson's disease, excess amounts of copper accumulate in the liver and brain, causing cirrhosis and dementia. When the liver is involved, alpha-1-antitrypsin deficiency and Wilson's disease tend to present as hepatitis in the neonatal period or in childhood. Hemochromatosis typically presents in adulthood, with the onset of clinical disease usually after age 50. Ischemic hepatitis (also known as shock liver) results from reduced blood flow to the liver as in shock, heart failure, or vascular insufficiency. The condition is most
Liver disease have higher levels of deoxycholic acid (DCA), a product of bile acid alteration by certain gut microbes, and these microbes are increased with obesity. The excess DCA causes DNA damage and inflammation in the liver, which, in turn, can lead to liver cancer. A common form of liver disease is viral infection. Viral hepatitides such as Hepatitis B virus and Hepatitis C virus can be vertically transmitted during birth via contact with infected blood. According to a 2012 NICE publication, "about 85% of hepatitis B infections in newborns become chronic". In occult cases, Hepatitis B virus is present by HBV
