Long-term alcohol consumption by hepatitis B carriers can lead to chronic and persistent hepatitis activity and accelerate the process of cirrhosis leading to a significantly higher chance of liver cancer. The reasons for this are as follows: 1. alcohol can reduce the liver’s immune tolerance to hepatitis B virus, which leads to hepatitis activity; 2. alcohol has a negative effect on the effectiveness of antiviral therapy, increasing the rate of drug resistance and leading to the progression of cirrhosis; 3. alcohol and hepatitis B virus have a synergistic effect on liver damage, which leads to a significantly higher incidence of liver cancer. In conclusion, alcohol consumption by hepatitis B carriers is harmful and must be abstained from.
