The inflammation caused by Hepatitis C can lead to a build up of scar tissue (fibrosis), which can change the liver structure. It is harder for blood to reach all parts of the liver. Loss in blood supply will cause the liver cells to die.

It becomes more difficult for the liver to store nutrients and remove toxins.

If the virus is left untreated it can lead to cirrhosis, the liver tissue changes in structure, which can cause the liver to stop functioning.
