Hepatitis B is viral hepatitis B. If the patient actively cooperates with the treatment, it usually does not affect the life expectancy. If not actively treated, it can develop into chronic hepatitis, and the condition may develop into cirrhosis or even liver cancer in the middle or late stage, at which time the five-year survival rate of patients is less than 20%. Most of the patients with hepatitis B can smoothly inhibit viral replication after using the drug, so that the condition stabilizes and stops progressing. Generally, without cirrhosis, after active treatment, patients can live to the normal life expectancy. If hepatitis B patients do not have timely antiviral and hepatoprotective treatment, leading to aggravation of the disease, secondary cirrhosis and liver cancer, these patients are difficult to cure, and the five-year survival rate is less than 20%. Therefore, hepatitis B patients should be treated as early as possible, regular review during the treatment period, pay more attention to rest, quit smoking and drinking, can be appropriate exercise, ensure balanced nutrition.
