The most characteristic vascular complication of diabetes is microangiopathy, which is a characteristic manifestation because the entire hyperglycemic state of diabetic patients will affect the microcirculation, resulting in corresponding changes in the intima of the microcirculation, which will lead to the appearance of the corresponding complications. The most common microvascular complications are diabetic retinopathy and diabetic nephropathy, and the current diagnostic standard of diabetes is also based on the incidence of diabetic microvascular complications as the entry point. The probability of diabetic microvascular lesions will be greatly increased. Therefore, for diabetic patients, reasonable control of blood glucose and prevention of the entire complication can maximize the prevention of complications such as diabetic microangiopathy, otherwise, whether it is retinopathy or nephropathy, it will have a great impact on the quality of life of patients.
