Hepatitis B virus carriers are not allowed to drink alcohol. Although a hepatitis B carrier is a person who has been infected by the hepatitis B virus but has not caused visible damage to the liver, the hepatitis B virus is still present in the body and can still cause damage to liver cells, although this damage cannot be detected by current tests. Therefore, drinking alcohol at this time can be a burden on the liver. The damage to the liver from these two substances can be superimposed, putting the hepatitis B carrier at risk of entering a state of chronic hepatitis B and developing impairment of liver function. In patients without hepatitis B infection, simple alcohol consumption can also cause liver damage, fatty liver, and even alcoholic hepatitis. When drinking alcohol in a state where the hepatitis B virus is infecting the body, these two factors are superimposed and can cause more damage to the liver.
