Not all hepatitis B must be treated, it depends on the specific examination of liver function, virus count, family history and so on. Hepatitis B is a common infectious disease in clinic, which is mainly transmitted through mother-to-child route, blood route and sexual contact route. Hepatitis B virus reproduces and replicates in large quantities during the illness, causing damage to liver function. As the disease progresses, it may develop into hepatitis and cirrhosis. Patients may need to receive treatment if they have an alanine aminotransferase value greater than twice the normal value, a high hepatitis B virus count, or a family history of cirrhosis, liver cancer, or other hereditary conditions. Because each patient’s specific condition is different, the need for treatment needs to be judged comprehensively and receive treatment under the guidance of a professional doctor. Patients with hepatitis B must receive antiviral treatment and liver-protecting treatment under the guidance of doctors specializing in gastroenterology to inhibit the reproduction and replication of the hepatitis B virus in the body as much as possible, and to reduce the damage to the liver.
