Having had hepatitis B for more than 10 years, this is the state of chronic hepatitis B infection, which will vary from person to person. If still in the carrier state, the patient will live as normal and the patient will not have abnormal changes in liver function or liver morphology. Therefore, such people are relatively lucky. However, there are some people who will experience immune clearance when they grow into adolescents or into adults, when the immune system destroys liver cells infected with the hepatitis B virus, and this is done to clear the virus. The hepatitis B virus cannot be completely removed by immune destruction; immune clearance is continuous or intermittent, and liver cells are subjected to continuous or intermittent damage, leading to liver fibrosis as well as cirrhosis. In this state, the liver is likely to decline in function, and in the decompensated stage of cirrhosis, the patient is likely to develop a series of symptoms, such as liver ascites, hepatic encephalopathy, and gastrointestinal bleeding, and other conditions that can be life-threatening. Therefore, patients with hepatitis B should have regular checkups to maintain the liver in a more normal form and avoid entering the stage of cirrhosis.
