Glycated hemoglobin reflects the blood glucose level in the last 2~3 months, and the normal range is 4~6%, 7.5% is on the high side. Generally, it can be lowered through lifestyle intervention and medication, and it is recommended to treat it under the guidance of a doctor. 1. Lifestyle intervention: patients usually choose low-salt, low-fat, low-sugar diet, avoid eating fried, high-sugar foods, eat less animal offal, crab and other high-cholesterol foods, quit smoking and limit alcohol. At the same time, moderate aerobic exercise, such as jumping rope, swimming, etc., and going to bed early and getting up early will help patients control blood sugar. 2. Medication: If blood glucose is still poorly controlled under diet and exercise treatment, patients should take glucose-lowering drugs such as glimepiride, acarbose and insulin injection as prescribed by the doctor, which can control blood glucose within the normal range. During the treatment, patients need to pay close attention to the blood glucose value, and seek timely medical treatment for any abnormality in the blood glucose value.
