The survival of a diabetic patient is related to the control of the disease by the patient and the physician, and cannot be generalized. Diabetes is a chronic disease that damages small and medium-sized blood vessels throughout the body. If patients can pay attention to it and carry out reasonable control of blood glucose, blood pressure, blood lipids, weight and diet, the damage caused by high blood glucose can be slowed down and some patients with good control even do not affect their life expectancy and are no different from normal people. However, without effective control, serious complications such as cardiovascular disease, diabetic foot, diabetic eye disease can appear in a short period of time, and even end-stage renal failure can develop. The average time from the appearance of proteinuria to the patient’s death from uremia is ten years, which can seriously reduce the patient’s quality of survival and survival period. Therefore, in daily life, diabetic patients should carry out strict dietary control, appropriate aerobic exercise, reduce the intake of carbohydrates, and take glucose-lowering drugs regularly.
