Hepatitis B is an infectious disease caused by the hepatitis B virus, with malaise, loss of appetite, nausea, vomiting, anorexia, hepatomegaly and abnormal liver function as the main clinical manifestations. Hepatitis B five is the most commonly used serum marker for the detection of hepatitis B virus infection in domestic hospitals, which has five main indicators, namely hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg) and hepatitis B e antibody (anti-HBe), hepatitis B core antibody (anti-HBc), through the two-and-a-half test can determine whether the infection is hepatitis B and the specific circumstances of the infection. Many patients go to a gastroenterologist for abnormal liver function and only find out they have hepatitis B after further examination. In addition, the treatment of slow hepatitis B is mainly antiviral therapy. Effective antiviral therapy can improve liver inflammation and necrosis, stop or delay the process of liver disease, reduce the incidence of cirrhosis and liver cancer, and extend the life of patients. However, antiviral treatment needs to be carried out for a long time, and complications such as drug side effects and virus resistance may occur during treatment. If patients stop the medication on their own, there is a risk of virus rebound, hepatitis recurrence, or even liver failure, which requires long-term follow-up by professional doctors to guide and supervise the treatment. Therefore, if you are suspected of having hepatitis B, it is advisable to seek medical attention from a liver disease specialist, especially an infectious disease hospital or infection unit, in order to get equal good treatment.
