Patients with diabetes combined with hepatitis B need to be seen according to the degree of the disease, which is not absolute, for example, the prognosis of patients with hepatitis B with major triplet, hepatitis B with minor triplet, hepatitis B carrier and active hepatitis varies greatly. Among them, patients with hepatitis B and major triple-positive or active hepatitis have the shortest life expectancy because this type of hepatitis is very likely to lead to cirrhosis and liver tumors in patients, and the disease may develop even more rapidly based on the presence of diabetes, and for patients with this type of disease life expectancy may be around 5 years or even shorter.
