The inflammation of liver tissues is also called hepatitis. Most often it is caused by the viruses parasitizing on the liver. The following factors may cause a liver disease:
• Toxic damage by alcohol, drugs, poisons, etc.
• Development of the cells leading to destruction of healthy of liver and tissues of bile ducts (an autoimmune disease).
• Failure in an exchange of iron and copper
• Failure in development alpha 1 – antitrypsin
The main distinction of viral and not viral hepatitis is in manifestation of symptoms and methods of treatment.
The viruses causing the liver disease parasitize and breed only in this organ; therefore, the infection can get to the liver of a healthy person just from somebody who is struck with this virus (blood transfusion, from mother to a fetus, injection with one needle).
Viruses of hepatitis affect cells of the liver. This is some kind of biological missionary work the purpose of which – to get into blood of the person and then if there is an opportunity turns up, to infect other potential object.
Hepatitis viruses mainly don’t destroy liver cells, they just use cells for reproduction, but they cannot manage to do it imperceptibly as human immunity is programmed on identification of the infected cells and their full destruction. That is why at viral hepatitis damage of liver tissues is revealed. Cells perish not at once. First they stop carrying out their functions correctly, and the more strongly immunity struggles with infection, the bigger quantity of cells sustains damage and the more considerably disorders in work of the liver are revealed.
