Diabetes is a chronic disease, but it is not a death sentence immediately after diabetes, if the blood sugar control is stable, the life expectancy of diabetic patients is not very different from normal people, and they can live 70 or 80 years. If blood glucose control is not stable, the life expectancy of a diabetic patient is about 1/3 of the remaining life expectancy, depending mainly on the control of one’s blood glucose. Blood glucose control is the cornerstone of diabetes, everything is fine if blood glucose is stable. If it is not stable, in addition to acute life-threatening complications such as acute acidosis and hypoglycemia, there are also chronic life-threatening complications such as hypertension, coronary heart disease, myocardial infarction, cerebral infarction, cerebral hemorrhage, as well as kidney failure and uremia. Therefore, the question of how long you can live with diabetes varies from person to person, as long as your blood sugar is stable and controlled in order to live a long life.
