China has about 93 million people with chronic HBV infection, including about 20 million cases of chronic hepatitis B. This has made China wear the hat of a major hepatitis B country. A large proportion of these infected people do not need antiviral treatment, so these infected people are left alone and ignored? For HBV infection that does not require antiviral treatment is not a carefree and worry-free. Because liver damage can occur as soon as the immune tolerance state is broken, it is important to pay attention to life conditioning and regular review. Chronic BHV infected people must do the following in their daily life: 1. Regular checkups Chronic BHV infected people should have regular checkups regardless of whether they have clinical symptoms, and how the liver function continues to be normal, every 3-6 months. 2. Absolute abstinence from alcohol Cirrhosis and liver cancer are mostly seen in men, in addition to the higher rate of HBV infection in men than in women, the prominent alcoholism in men compared to women is also one of the important reasons. Therefore, hepatitis B patients must absolutely refrain from drinking alcohol, even drinks containing alcohol. 3, never eat moldy food HBV-infected diet should be based on carbohydrates, eat more fresh vegetables and fruits, do not eat moldy food, such as moldy peanuts, soybeans and grains, etc.. Moldy food contains a large amount of aflatoxin, which is clearly associated with liver cancer. There are many causes of liver function abnormalities in chronic HBV carriers, not all of which are caused by active HBV replication. Drinking alcohol, taking liver-damaging drugs, obesity and other factors may cause liver function abnormalities, and at such times only liver-protective, symptomatic supportive treatment is needed. To accurately determine whether liver abnormalities are caused by HBV, in addition to a detailed medical history, a liver biopsy histopathological examination is required.
