How to measure postprandial blood sugar?

Question 1: How to measure postprandial blood sugar? Fasting blood sugar test should be done at 7-8 am after dinner 10 hour or more, and blood sugar should be checked 2 hours after the first breakfast. It is unnecessary to move more and less after meals. According to the normal law, hyperactivity after meals will affect the blood sugar test results.

Question 2: How to measure blood sugar 2 hours after a meal? Count for two hours from the first bite, and then draw blood to measure blood sugar.

Question 3: How to measure blood sugar two hours after a meal? Two hours after meals, blood sugar measurement is from the beginning of eating to taking venous blood for 2 hours. After eating normally, I will not eat other foods or non-staple foods, fruits, etc.

Question 4: Why should we pay attention to the determination of postprandial blood sugar? The determination of blood sugar is of great significance to diabetic patients. It is not only the main basis for diagnosis of diabetes, but also an important index reflecting the therapeutic effect of diabetes. Recently, I talked with several "elderly" diabetic patients about blood sugar testing, and found that they only know how to test their blood sugar on an empty stomach, but they don't know whether they should test their blood sugar all day, let alone the special significance of measuring their blood sugar after meals, before going to bed and at night. The conversations with these diabetic patients are recorded as follows for readers' reference. 1. By measuring postprandial blood sugar, the diagnosis time of diabetes can be advanced by 3 ~ 5 years. I told him: "The blood sugar level of human body will fluctuate to a certain extent with activities such as eating and sleeping, and it will be at a relatively high level for a long time after meals. In the early stage of diabetes, when the patient's fasting blood sugar is still at a normal level, his postprandial blood sugar has already appeared abnormal. " Teacher Zhang looked puzzled after listening to my words, and I further explained: "When people are on an empty stomach, because food has been consumed after a long period of digestion, the human body will temporarily lose the main source of blood sugar, and then the blood sugar value will be at a relatively low level, so it is not easy to find diabetes by detecting the blood sugar value on an empty stomach. In fact, eating is a simple sugar load test, which can expose the sugar utilization disorder of diabetic patients immediately. Studies have found that postprandial hyperglycemia occurs 3 to 5 years earlier than fasting hyperglycemia. " Teacher Zhang couldn't help but ask in surprise: "So, by measuring postprandial blood sugar, the diagnosis of diabetes can't be advanced by 3 to 5 years?" I nodded solemnly and said, "Because the measurement of postprandial blood sugar is of great significance in the diagnosis of diabetes, people who are suspected of having diabetes must first measure postprandial blood sugar to improve the accuracy of blood sugar detection. Generally speaking, after a person eats100g of staple food, his blood sugar is greater than or equal to11.1mmol/L (140 ~ 200mg100ml) 2 hours after meals. Second, blood sugar monitoring should be carried out around the clock. Manager Li has been suffering from diabetes for several years. He brought his own fast blood glucose meter to control fasting blood glucose perfectly. After hearing my conversation with teacher Zhang, he came over and asked, "So, how to monitor blood sugar is correct?" I told him: "If you want to fully understand your blood sugar level, you should monitor your blood sugar around the clock, that is, you should not only check your fasting blood sugar, but also check your blood sugar when you sleep after meals. This is because blood sugar is in a state of fluctuation, and a measured blood sugar value can only reflect the blood sugar level at that time, but not the change of blood sugar in a day. However, only when the blood sugar of patients with hyperglycemia is at normal or near normal level all day, the treatment result can be satisfactory. " Manager Li interjected at this moment: "I usually only measure my blood sugar once before breakfast." Is it not comprehensive enough? " I smiled and said, "Yes. When the blood sugar of diabetic patients is unknown or unstable, the blood sugar can be measured 8 times a day, that is, 1 time before and after three meals, before going to bed at night and at 2 am. The ideal blood glucose level of diabetic patients should be: fasting blood glucose is less than or equal to 6. 1 mmol/L, postprandial blood glucose is less than or equal to 8.3 mmol/L, postprandial blood glucose is less than or equal to 7.2 mmol/L in 2 hours, and postprandial blood glucose is less than or equal to 6. 1 mmol/L in 3 hours, and no hypoglycemia occurs all day. The better blood glucose level of diabetic patients should be: fasting blood glucose is less than or equal to 7.2 mmol/L, 1 hour postprandial blood glucose is less than or equal to 10.0 mmol/L, 2 hours postprandial blood glucose is less than or equal to 8.3 mmol/L, 3 hours postprandial blood glucose is less than or equal to 7.2 mmol/L, and no hypoglycemia occurs all day. " Third, postprandial hyperglycemia is the inducement of various diabetic complications. Master Wang is 60 years old and has been suffering from diabetes for more than ten years. He usually pays great attention to treatment, urine sugar has been negative, and fasting blood sugar is basically controlled within the normal range. Recently, however, Master Wang began to have symptoms of chronic complications of diabetes, such as numbness of lower limb skin, blurred myopia and low urine protein. To this end, he wondered: How can there be complications if fasting blood sugar is well controlled? After listening to my conversation with the above two patients, he asked me, "Are my complications also related to postprandial hyperglycemia?" I asked him, "Do you usually ... >>"

Question 5: When is the best time to measure blood sugar after meals? When is the time to measure blood sugar before meals?

Question 6: What is the postprandial blood sugar value? What is the normal value of normal blood sugar?

Key words: What is the normal value of blood sugar? Hyperglycemia treatment in diabetes hospital

What is the normal value of blood sugar? Do you know the normal value of blood sugar? Yang Jie, director of the Diabetes Treatment Center of the Third Hospital of Beijing Armed Police Corps, introduced "What is the normal value of blood sugar": Now there are more and more diabetes, and the blood sugar value at the time of onset is generally not within the normal range of blood sugar. We can check it ourselves from here. So as to prevent and treat diabetes as soon as possible. There are many ways to check the blood sugar level now, and friends can measure it according to the actual situation.

The diagnosis of diabetes should be judged from two aspects: fasting blood glucose value and two hours after meals. Normal range of fasting blood glucose:

The normal range of fasting blood glucose was 3.9-6.1mmol/l (70-110 mg/dl), which was higher than that of the control group.

7.0mmol/L( 126mg/dL) was diagnosed as diabetes. Then the diagnostic standard of fasting diabetes is 7.0 mmol or 126 mg. It can be seen that there is a gap between the normal value and the fasting diagnosis of diabetes. Some people are neither normal nor diabetic. We call this symptom elevated fasting blood sugar (impaired). Normal range of postprandial blood glucose:

Two hours after a normal meal, the blood sugar range is 3.9-7.8 mmol/L (70-140 mg/dl). The diagnostic criteria of postprandial blood glucose are 1 1. 1 mmol or more than 200 mg. Then there is a gap between 140 and 200. If blood sugar is at this stage, we call it postprandial hyperglycemia. This kind of person is neither diabetic nor normal. However, it is dangerous for such people to have high blood sugar, and it is easy to get diabetes. Such people must be careful. The hat hangs on his head. If you don't pay attention, you will soon wear a hat of diabetes. Even people with completely normal blood sugar should pay attention to preventing diabetes if there are some high-risk factors.

Hyperglycemia is also one of the three highs. In modern society, due to the improvement of living standards and bad living habits, many people may have hyperglycemia. If it is not found and controlled in time, it will be in danger of developing diabetes.

Through the above introduction, we know that the blood sugar level of diabetes can be used as a detection standard of diabetes. Therefore, if a friend suspects that he has diabetes or has a self-examination, he can confirm it through the normal range of blood sugar.

Blood sugar is normal, fasting blood sugar is generally 3.9 ~ 6.1mmol/L (70 ~110 mg/dl), and plasma glucose is 3.9 ~ 6.9 mmol/L (70 ~125mg/dl). After 1 hour, the blood sugar can rise to10mmol/l (180mg/dl) and return to 7.8 ~ 8.9mmol/l (140 ~160mg/dl) 2 hours after meals. Therefore, after three meals a day, people's blood sugar rises for 2 hours (***6 hours), and the rest 18 hours is at fasting blood sugar level.

Question 7: When will the postprandial blood sugar be measured? Blood should be drawn two hours after meals. That is, the time is counted from the first bite of rice, and the blood sugar is measured after 2 hours. Two hours postprandial blood glucose is an important index of islet β cell reserve function, that is, the ability of food β cells to secrete insulin after eating. If the function is good, the surrounding tissues are sensitive to insulin and have no insulin resistance, the blood sugar value should be reduced to 4.6 ~ 7.8 mmol/L 2 hours after meals. However, if the reserve function is good, even some diabetic patients secrete more insulin than normal people, but because the surrounding tissues are resistant to insulin, or the insulin resistance is not obvious, the function of islet β cells is poor, and the blood sugar can be significantly increased 2 hours after meals.

Question 8: Measuring blood sugar several hours after meals to control diabetes tells you that blood sugar is usually measured two hours after meals.
