Diabetes can lead to a variety of complications, and there are differences in survival for patients with different diabetic complications. Patients with diabetes combined with diabetic retinopathy will generally not affect survival, but will only affect the patient’s vision and eventually become blind in both eyes. Patients with diabetes combined with diabetic nephropathy can be maintained by dialysis. As long as the kidney dialysis is performed on time, it usually will not affect the survival period of patients, and if the disease progresses to uremia, the survival period of patients is about 3-5 years. Patients with diabetes combined with coronary arteriosclerosis or acute myocardial infarction may die if they do not receive timely treatment. Therefore, the survival of patients with diabetic complications is related to the different complications and their severity. The majority of patients with type 2 diabetes die from macrovascular complications. Patients with diabetes should have a correct understanding of the disease, maintain an optimistic attitude, standardize and reasonably carry out glucose-lowering treatment under the guidance of professional clinicians, do a good job of monitoring blood glucose dynamics, eat a healthy diet, and exercise appropriately to prevent the occurrence of diabetic complications.
