Many diabetic patients are very attentive to diet control, exercise therapy and the application of glucose-lowering drugs, but they do not take seriously what their doctors say about blood glucose monitoring, which is actually an important part of diabetes treatment. These patients think that as long as they pay attention to their diet, exercise more and don’t forget to use medication, their blood glucose will not rise naturally. Some patients are also reluctant to monitor their blood glucose because they are afraid of poor blood glucose control, which is a self-deceiving treatment. There are two hazards of not monitoring blood glucose: First, asymptomatic hypoglycemia occurs without knowing it, and medication continues to be used until serious hypoglycemia threatens life. Second, not knowing the elevated blood sugar, not adjusting the medication in time, failing to achieve the therapeutic effect, and being in the state of high blood sugar for a long time, complications are inevitable. Wei Jing, endocrine specialist of Jinan Hospital of Traditional Chinese Medicine So, how to carry out blood sugar monitoring? Blood glucose monitoring includes fasting blood glucose, 2-hour postprandial blood glucose and glycated hemoglobin, and if necessary, blood glucose spectrum testing. Fasting blood glucose is the basic blood glucose value, which refers to the blood glucose value in the state of not eating for 6 to 8 hours, and patients are recommended to check it once every 1 to 2 weeks. The 2-hour postprandial blood glucose is the blood glucose value calculated from the first meal to 2 hours, and it is recommended to check it together with fasting blood glucose. Glycosylated hemoglobin refers to the average blood glucose value of the patient from 8 to 12 weeks, which is the gold indicator of diabetes treatment at present. Blood glucose profile refers to the blood glucose monitoring which includes 8 times before three meals, 2 hours after three meals, 10 o’clock before bedtime and 3 o’clock in the morning, which can show the changes of blood glucose during the day, and it is recommended for patients to test when their blood glucose fluctuates. In addition, diabetic patients should also have blood pressure, blood lipids, urine microalbumin and fundus artery examination every six months to better prevent complications.
