There is no such thing as what the surface antigen of hepatitis B is lower than in order to be easily cured by oneself, the self-healing of hepatitis B has nothing to do with the hepatitis B surface antigen index. Generally, acute hepatitis B can be cured on its own, but chronic hepatitis B requires systemic treatment and is usually difficult to cure. Hepatitis B surface antigen is one of the signs of hepatitis B virus infection, which can indicate whether you have been infected with hepatitis B virus in the past or are currently infected with hepatitis B virus, so there is no such thing as how much the hepatitis B surface antigen is lower than that can easily be cured, and there is no direct relationship between the index of the hepatitis B surface antigen and the ability of hepatitis B to be cured by itself. Under normal circumstances, hepatitis B surface antigen is negative. Hepatitis B can be categorized into acute and chronic. In general, acute hepatitis B has the possibility of self-healing, but the chance is not high. In the case of chronic hepatitis B, because it is difficult to heal by itself, it is necessary to cooperate with the doctor to take medication or surgical treatment for systematic treatment. All in all, patients must cooperate with doctors for active treatment, strengthen daily life management, go to the hospital for follow-up on time, and closely monitor the changes of hepatitis B indicators.
