Can having diabetes affect my hepatitis B? Having both hepatitis B and diabetes can increase your chances of developing liver cancer. Therefore, for people with hepatitis B, preventing or managing diabetes is particularly important. If you have hepatitis B and diabetes, you need to manage both conditions carefully in consultation with your doctor. Remember, a healthy lifestyle is important for both hepatitis B and diabetes so it is important to eat healthy, exercise and avoid alcohol and tobacco. References: Hepatitis B Foundation.
