1. Fasting blood glucose
Refers to the overnight blood sugar at 6-7 in the morning, 8-10 hours without eating. Fasting blood glucose reflects the basic secretion of insulin, and can also reflect whether the medication taken the night before can control blood glucose to the next morning. As the starting point of blood glucose changes throughout the day, fasting blood glucose has a predictive effect on postprandial blood glucose level.
2. Blood sugar before meals:
Blood sugar levels before lunch and dinner. It reflects the continuity of secretory function of islet B cells. Preprandial blood sugar can guide patients to adjust the amount of insulin injection or oral medication before meals, and can also detect asymptomatic hypoglycemia. When blood sugar levels are high or at risk of hypoglycemia (the elderly, better blood sugar control), blood sugar before three meals should be measured.
3. 2h postprandial blood sugar
Refers to 2 hours after breakfast, lunch, and dinner when the first bite starts to count. It mainly reflects the secretion of insulin during meals, evaluates the effect of drug treatment and adjusts the drug treatment plan. Fasting blood glucose was well controlled, but the glycated hemoglobin was still not up to standard. Attention should be paid to the blood glucose 2 hours after meals.
4. Blood sugar before bedtime
Measuring blood sugar at night before going to bed. It is used to judge the effect of drug treatment and whether additional meals are needed to prevent hypoglycemia. It is suitable for patients who inject insulin, especially those who inject long-acting insulin.
5. Blood sugar in the morning
Blood sugar levels between 2 and 4 a.m. It is suitable for those whose blood sugar is close to the standard after treatment, but the fasting blood sugar is still high, or those who are suspected of having low blood sugar at night, and the cause of fasting high blood sugar can be distinguished (Sumujie phenomenon/dawn phenomenon).
6. Random blood sugar
Blood glucose at any time other than the specified blood glucose monitoring time above. When the symptoms of hypoglycemia appear, before driving, before and after strenuous exercise, cold and fever, mood fluctuations, random blood sugar should be timely measured, and blood sugar changes under special circumstances should be captured at any time.
○ Pay attention to blood glucose monitoring records
Good blood glucose monitoring records can help sugar friends manage blood glucose. Carrying blood glucose monitoring records can make it more convenient to communicate with doctors about their condition and provide evidence for adjusting treatment plans. Records should include: blood glucose monitoring time, blood glucose value, food intake and eating time, exercise amount and exercise time, dosage and time of medication, insulin amount and injection time, and records of some special events, such as diarrhea and fever.
