The life expectancy of patients with diabetes combined with hepatitis B is about 10 years, but of course it is not absolutely related to the patient’s type of hepatitis B. For example, the prognosis of patients with hepatitis B with triple positive, hepatitis B with triple negative and hepatitis B with carrier patients varies a lot. The life expectancy of patients with hepatitis B with triple positive is the shortest, because this type of hepatitis is very likely to lead to cirrhosis, liver tumors, and the presence of diabetes on the basis of the disease may develop even more rapidly, and the life expectancy of patients with this type of disease may be around 5 years or even shorter.
