Introduction: Diabetes is a very common chronic metabolic disease in my country. At present, the number of diabetic patients in my country is very large. According to previous relevant Statistics show that about 9.76% of adults over the age of 20 in our country have related problems.

So the most important thing for diabetics is to control their blood sugar levels well, but we And how to judge whether your blood sugar control is good or not?

Perhaps you will first think of going Test fasting blood sugar or postprandial blood sugar, but many people think that it is a little troublesome to test this way. You can’t test it every day or every time you eat, right?

So is there any other better way to detect blood sugar? Of course there is! There is a way called glycated hemoglobin! It is known as the “gold standard” of blood sugar control. Perhaps everyone is not familiar with it. I believe that after reading the following content, you will be able to understand this test very well.

Blood sugar Hazards of Elevation

Sustained increase in blood sugar will have multiple impacts on health:

1. Injury to major blood vessels, mainly cardiovascular and cerebrovascular, will increase the occurrence of acute cardiovascular events such as stroke and myocardial infarction to varying degrees;< /span>

2. Damage to nerve tissue may easily lead to limb numbness, pain, and even visceral dysfunction;

3. Damage to the microvessels mainly in the retina and kidney, which may cause kidney damage and vision loss in the short term Problem;

4. It will easily aggravate the damage of pancreatic β cells, and the body’s ability to secrete insulin will continue to decline , which will continue to increase the difficulty of lowering blood sugar.

what Is it glycated hemoglobin?

For normal people, there are three kinds of hemoglobin in the body, namely: HbA, HbF, and HbA2, and the red blood cells of normal people are mainly HbA.

HbA1c refers to glycosylated hemoglobin, the glycosylated hemoglobin we all talk about.

Glycated hemoglobin refers to the slow, continuous and irreversible non-enzymatic process of hemoglobin and glucose in red blood cells Product of pro-protein glycation reaction.

Gold standard for blood sugar control – glycosylated hemoglobin

Compared with fasting blood sugar and blood sugar levels two hours after a meal, glycosylated hemoglobin can not only reflect the blood sugar level at a specific time point, but also mainly reflect the overall control status of blood sugar in the past three months.

Moreover, glycosylated hemoglobin also has different values ​​in the adjustment of hypoglycemic programs.

1. Can help stress diabetes and hyperglycemia, cerebrovascular, emergency and other stress states

2. It helps to improve patients’ awareness of chronic complications of diabetes. A relatively high value of hemoglobin will easily lead to complications of diabetes symptoms, such as myocardial infarction, diabetes, kidney disease, cataract, arteriosclerosis, stroke, etc.;

3, Glycated hemoglobin level is a very important indicator of diabetes control during pregnancy.

So all in all, glycosylated hemoglobin is a “golden indicator” for measuring blood sugar standards, and it is also helpful for diagnosis And an important “helper” in the treatment of diabetes.

How much is the best blood sugar control gold standard “glycosylated hemoglobin”?

According to the current standards in our country, the level of glycosylated hemoglobin ≥ 6.5% has reached the diagnostic standard of diabetes.

So naturally some people think that diabetic patients need to control the glycated hemoglobin level within 6.5% , but in fact such an idea is completely wrong, most of the time it is not the case.

According to the 2020 edition of “China Type 2 Diabetes Prevention Guidelines, which provide comprehensive diabetes control goals, do not require all patients to reduce the glycated hemoglobin level to less than 6.5%.

It is recommended in the content that most patients need to reduce the glycated hemoglobin to less than 7.0%. That’s enough.

Many friends may find it a little strange to see here, why patients are not required to take glycosylated hemoglobin How about controlling the level to a standard closer to the normal level?

This is mainly due to At present, there is no high-quality clinical research to prove that reducing the glycated hemoglobin level to less than 6.5% in most diabetic patients can significantly increase the cardiovascular protective effect.

However, there are also clinical studies that have found that this will increase the risk of adverse reactions such as hypoglycemia, and also It will easily significantly increase the medical burden of the society as a whole.

The control target of the glycated hemoglobin level of most patients is set at “<7.0% ", you canIt is enough to better take into account the corresponding balance between cardiovascular protective effect and adverse reactions.

However, the blood sugar control goals of diabetic patients are never static, and need to be personalized according to individual conditions set up.

For example, the course of disease Shorter, younger age, long life expectancy, no complications, no cardiovascular disease, etc. For this part of the patients, it is indeed possible to consider controlling the glycated hemoglobin level to less than 6.5%.

For those who have a long course of disease and have already experienced cardiovascular diseases such as cerebral infarction, coronary heart disease, and stroke For patients with diseases, it is necessary to appropriately relax the control target of personal glycated hemoglobin level, and relax it to “<8.0%".

Moreover, those middle-aged and elderly patients with poor overall health can control the level of glycated hemoglobin The target can be further relaxed, and it can be relaxed to “<9.0%".

How much blood sugar control gold standard “glycosylated hemoglobin” should be taken?

The level of glycated hemoglobin can not only reflect the control of blood sugar, but also help people judge whether they need to take hypoglycemic drugs Treat accordingly.

Under normal circumstances, if you are newly diagnosed with diabetes, your glycated hemoglobin is between 6.5% and 7.0% , fasting blood sugar and two-hour postprandial blood sugar did not have a particularly extreme rise, and at the same time did not have any cardiovascular disease or diabetes complications, in this case, you can temporarily not take any hypoglycemic drugs.

For patients who meet this condition, exercise can be done first, followed by diet control, etc. A healthy lifestyle is used to intervene in hypoglycemia. After all, my own glycosylated hemoglobin level is still within 7.0%.

However, for patients with glycosylated hemoglobin levels exceeding 7.0%, it is necessary to follow the doctor’s advice and take hypoglycemic drugs reasonably. And if there are other complications, it is even more necessary to use rational medication.

How often should the HbA1c be rechecked?

Finally, there is another question that everyone is more concerned about, that is, how often is the best time to recheck the glycated hemoglobin?

In fact, this needs to be determined in combination with personal blood sugar level, diabetes type and treatment plan:

1. If you are already a diabetic patient, it is best for type 2 diabetic patients to review the glycated hemoglobin twice a year. Patients with type 2 diabetes need to recheck the glycosylated hemoglobin 3~4 times a year;

2. If you are a People at high risk of diabetes are what we all call people with abdominal obesity, or those who are already in the pre-diabetes stage. It is recommended to check the glycated hemoglobin once a year at this time;

3. For those who have long-term unsatisfactory blood sugar control and diabetic patients who have recently changed their treatment plan, they need to recheck the level of glycosylated hemoglobin every 2 to 3 months.

Conclusion: After reading this article, you may have a new understanding of the level of glycosylated hemoglobin, and I hope you can really understand this Take advantage of this check, so that you can better control your blood sugar problems.
