Clinically, diabetic patients need regular monitoring of various indicators during the treatment process to understand the effect of treatment, whether the indicators meet the standards and the situation of chronic complications of diabetes, to achieve early detection, early prevention and early treatment. The clinical monitoring indicators include the following: 1. blood glucose, regular monitoring of fasting blood glucose, 2-hour postprandial blood glucose, and glycated hemoglobin once every 2-3 months. 2. blood pressure monitoring, blood pressure in diabetic patients needs to be controlled below 130/80 mmHg. 3. lipid monitoring, total cholesterol in diabetic patients needs to be controlled below 4.5 mmol/L. For patients without cardiovascular or cerebrovascular complications, low-density cholesterol (LDL) should be monitored. For patients without cardiovascular complications, LDL cholesterol should be controlled below 2.6 mmol/L. For patients without cardiovascular complications, LDL cholesterol should be controlled below 1.8 mmol/L. 4. Weight monitoring, weight management for diabetic patients, patients need to keep their weight within the standard weight to avoid overweight or underweight. 5. early treatment. For patients without diabetic fundus lesions, the fundus can be monitored once a year. 6. Urine microalbumin monitoring, for diabetic patients, urine microalbumin needs to be monitored once every 3 months to understand whether there is diabetic nephropathy, so as to achieve early detection and early treatment.
