We have talked about the different meanings of different blood sugar indicators. We have talked about the different meanings of fasting blood sugar, 3 a.m. blood sugar, pre-meal blood sugar and two-hour post-meal blood sugar. Today we continue to talk about the different meanings of blood sugar in different time periods.
Bedtime blood sugar: reflects the body's ability to control high blood sugar after eating. Monitoring blood sugar before going to bed is mainly to guide nighttime medication or insulin dosage to avoid hypoglycemia at night.
Random blood sugar: refers to blood sugar measured at any time during the day, and should be checked at any time when hypoglycemia or obvious hyperglycemia is suspected. The random blood sugar of normal people does not exceed 11.1mmol/L.
Glycated hemoglobin (HbA1c): Glycated hemoglobin is the target for evaluating long-term blood sugar monitoring. It is usually tested once every 3 months to reflect the overall situation of blood sugar control in 2-3 months.
Glycated hemoglobin cannot be detected with a blood glucose meter, but it can be used to determine the accuracy of blood glucose self-test results and whether the frequency of monitoring is sufficient. According to Chinese standards, the HbA1c target is <7.0%. Its level is related to the average blood sugar level, so the average blood sugar value displayed by the blood glucose meter within a certain period of time (7/14/30 days) can reflect the level of glycated hemoglobin to a certain extent. For example, the average blood sugar is 7.5mmol/L, the HbA1c level is roughly around 6%, and the blood sugar is well controlled. If the average blood sugar is 15.5mmol/L, the HbA1c level is most likely to have exceeded 10%, and blood sugar control needs to be adjusted urgently.
