Hepatitis B surface antigen is greater than 500ng/ml, first of all, we should further look at the other items in the Hepatitis B tri-system to see whether the patient is a minor triple positive or a major triple positive. If the patient is small triple positive, there is no viral replication, and if the liver function is normal, the patient can continue to observe. If it is triple positive, then further blood should be drawn to check hepatitis B DNA to see if the virus has replication, if there is a combination of viral replication, and the liver function of glutamic oxal transaminase is elevated, then we should actively consider antiviral treatment. You can choose oral antiviral drugs, such as tenofovir, entecavir and other drugs, you can also actively consider interferon injection, half a year to one year of injection, after active antiviral treatment, most patients will be viral replication control, the patient’s hepatitis B is also under control. Usually patients should pay attention to do not drink alcohol, do not stay up late, do not labor, and in the diet, do not binge drinking, for the drier, harder food, try not to eat. Because for some patients with hepatitis cirrhosis, there will be fundic esophageal varices, and it is possible that patients may eat too hard, too hot food, causing the possibility of varices rupture.
