Diabetic patients should pay attention to reasonable diet and exercise, regular use of medication, regular monitoring of blood glucose and so on. 1. Reasonable diet and exercise: In terms of diet, we should strictly control the daily energy intake, low salt, low fat, low carbohydrate, and appropriate exercise, such as swimming, jogging, brisk walking, yoga and so on. 2. Regular medication: Diabetes is a chronic disease, a lifelong disease that requires lifelong treatment. It is important to take medication every day according to the doctor’s prescription, avoiding overdose or omission of medication to avoid serious adverse reactions. 3. Regular monitoring of blood glucose: once diagnosed, diabetic patients need long-term blood glucose monitoring, usually at home to monitor their own fasting and postprandial blood glucose, and regularly go to the hospital to monitor glycated hemoglobin, liver and kidney function. Diabetic patients should follow the doctor’s instructions for treatment and regular review.
