What are the complications of Hepatitis C?
Hepatitis C virus does not damage the liver. Liver damage is due to the body’s immune system trying to fight the hepatitis C virus. Liver damage can be measured by blood tests such as ALT (also called SGPT).
If liver damage is prolonged, the liver becomes scarred (liver cirrhosis), which can lead to liver failure and liver cancer and early death.
All these complications are potential life-threatening.
