Survival in men with diabetes is related to glycemic control and varies from person to person. Due to the high metabolism and social stress in men with diabetes, which can significantly affect the endocrine metabolism and organ damage of patients, the survival period of men with diabetes is shorter than that of women with diabetes. If diabetic patients can control their blood sugar to keep it stable and avoid diabetic complications, they can obtain the same quality of life and life expectancy as healthy people. If the blood sugar is not well controlled, it may cause diabetic complications, such as diabetic retinopathy and diabetic nephropathy, and death may occur in serious cases. Male diabetic patients must go to the endocrinology department of regular hospitals in time, actively cooperate with doctors for treatment, maintain a good attitude, regular rest and rest, avoid foods with high sugar content, strictly prohibit smoking and drinking alcohol, do a good job of dynamic monitoring of blood sugar and regular review.
