There is no such thing as most hepatitis B carriers will not develop disease. If patients need to insist on regular review, once abnormal liver function occurs, active treatment, the prognosis is better. Some patients may develop into cirrhosis and liver cancer with poorer prognosis. Hepatitis B carriers are caused by hepatitis B virus infection. Hepatitis B virus can be transmitted through mother-to-child, blood or blood products, and sexual contact. Hepatitis B carriers are usually asymptomatic or have mild symptoms, which may only manifest as intermittent fatigue, weakness, and discomfort in the liver area. Usually, if the patient does not have any uncomfortable symptoms, it is enough to follow the doctor’s instructions for regular checkups, and no special treatment is needed. However, if the patient has abnormal liver function and meets the indications for antiviral treatment, antiviral treatment is required, and oral antiviral drugs such as entecavir and tenofovir can be taken as prescribed by the doctor. If treatment measures are not taken in time, it may lead to disease aggravation and development of cirrhosis, or even liver cancer, which will seriously jeopardize the health of patients. It is recommended that patients who are hepatitis B carriers should follow the doctor’s instructions for regular checkups.
