Hepatitis B

Without treatment, about a third of people with chronic hepatitis B infection go on to develop a disease of the liver, which can be very serious. 

It is estimated that 15–25% of people with chronic hepatitis B die of liver disease.

Cirrhosis

Many people develop cirrhosis (scarring of the liver). When this happens, the liver can no longer carry out its normal functions and liver failure occurs. The only treatment for liver failure is to have a liver transplant.

Liver cancer

Chronic hepatitis B is also associated with an increased risk of developing liver cancer.
