Introduction: Nowadays, diabetes has become a very common chronic metabolic disease. The main cause of the disease is closely related to insufficient insulin secretion or insulin dysfunction. When the sugar concentration in the blood increases, if effective treatment is not carried out in time, will easily induce hyperglycemia , and in severe cases it will easily lead to diabetes.
In the past, diabetes was also called "rich disease". Once you suffer from this disease, you need to take medication for life. If the situation is serious, also requires lifelong injection of insulin .
According to relevant disease data investigations, the number of diabetes patients in my country can reach about 153 million. The high-risk inducing people are middle-aged and elderly people aged 45 to 58. The complete cure rate is only 5.3%, and the risk of sudden death can reach 21.86%.
If you want to determine whether you have diabetes, you must clarify your blood sugar level. Whether during the physical examination or during the daily test, once finds that you have an elevated blood sugar level, you must be alert in time.
Night urine output
The blood sugar level in the patient's body increases, and the blood will become sticky, causing the reabsorption of urine by renal tubules , which can easily lead to the problem of increased urination.
urination times will also increase at night. will not only cause discomfort in the urinary system, but also easily affect your own sleep.
The blood sugar in the patient's body increases and the blood becomes viscous, resulting in a decrease in renal tubules' reabsorption of urine and causing increased urination. Especially when you get up at night, the number of urination will increase. will not cause discomfort, but it will also cause poor sleep.
Fatisure and weakness
Although Glucose is the main source of body energy, if there is too much sugar in the blood and The body cannot use it normally, it will easily aggravate fatigue and fatigue.
numbness of hands and feet
0 The long-term increase in blood sugar levels will make the blood too sticky. At this time, it will easily lead to a series of metabolic disorders of nerve fibers, which will lead to numbness of hands and feet , especially at night, the problem of numbness of limbs will be very serious.
What is fasting blood sugar , postprandial blood sugar?
Fasting blood sugar definition:
Fasting blood sugar refers to the body. After eating any food at least 8 to 10 hours on an empty stomach overnight, the blood sugar value obtained by drawing blood sugar before breakfast is taken. Empty abdominal blood sugar can reflect the function of the body's pancreatic β cells and can also effectively reflect the body's blood sugar metabolism problems.
Under normal circumstances, the body's fasting blood sugar range is between 3.89~6.1mmol/L. If the fasting blood sugar level is lower than 2.81mmol/L and there are corresponding clinical manifestations, you should consider whether there is hypoglycemia at this time;
If fasting blood sugar is present, if there is a problem of hypoglycemia;
If fasting blood sugar is present, please consider whether there is a problem of hypoglycemia; The value is between 6.1 and 7.0mmol/L. should consider abnormal fasting blood sugar levels at this time;
If the fasting blood sugar value is greater than or equal to 7.0mmol/L, it is necessary to consider whether it is hyperglycemia or diabetes. Further go to the hospital for corresponding examination, such as oral glucose tolerance test.
Post-meal blood sugar definition:
Post-meal blood sugar actually refers to a blood sugar measurement conducted from the first staple food to two hours. After-meal blood sugar includes one hour, two hours, and three hours of measurement.
Through the understanding of postprandial blood sugar , we can further determine whether there are sugar metabolism abnormalities in the body's sugar load.
and can be combined with the determination of insulin level to further evaluate whether the secretion of insulin by pancreatic , and whether the blood sugar value of and two hours after meals is 7.8 mmol/L.
The blood sugar in one hour after the meal does not have an absolute normal value, but the doctor found that if the blood sugar in one hour after the meal is ≥11.1mmol/L, the risk of diabetes will increase significantly . It is necessary to actively prevent the problem of increased blood sugar in a reasonable form.
If the blood sugar is ≥11.1mmol/L two hours after the meal, diabetes can be diagnosed.
Fasting blood sugar or postprandial blood sugar, which is more important? If you don’t understand this, it may be equivalent to the white test
. Related studies have found that when glycated hemoglobin level is 7.3~8.4%, the effects of blood sugar and postprandial blood sugar on the overall blood sugar are generally comparable to about 50%.
When the glycated hemoglobin level is greater than 5%, shows that fasting blood sugar has a greater impact on overall blood sugar than postprandial blood sugar.
However, as the level of HbA1c increases, the impact of fasting blood sugar values on glycated hemoglobin will also increase.
When the glycated hemoglobin level is less than 7.3%, the effect of postprandial blood sugar on the overall blood sugar is greater than that of basal blood sugar, which means that the increase in blood sugar mainly depends on postprandial blood sugar.
However, in clinical practice, the fasting blood sugar level of some diabetic patients may be normal, but the postprandial blood sugar is relatively high, even ≥11.1mmol/L. If you only check fasting blood sugar, may cause many diabetes to miss diagnosis.
The contribution of fasting blood sugar in the middle and late stages may be greater, because this indicator can objectively reflect the patient's basal insulin level , and can also be more helpful in monitoring and adjusting blood sugar levels.
So from these aspects we can see that fasting blood sugar and postprandial blood sugar are very critical indicators for the diagnosis and monitoring of diabetes.
also did not say which one is more important, because both of them are very important!
When is the best time to test blood sugar in ?
For those who need to stabilize blood sugar control, as well as patients with unstable blood sugar, blood sugar needs to be measured multiple times during normal times, and some patients even need to take 24/7 measurements. So when is it better to measure blood sugar?
Fastling blood sugar: After 8-10H overnight, it is best to measure it from 6:00 to 8:00 in the morning of the second day;
Before meal blood sugar: This is to measure blood sugar before eating;
Fastling blood sugar: It refers to measuring blood sugar for two hours after 33, but everyone needs to start from the time of eating at the first mouth;
Hastling blood sugar : It refers to the blood sugar measured at any time in the day, including nighttime blood sugar, before bedtime blood sugar, etc.
Conclusion: In short, for patients with diabetes and hyperglycemia, both fasting blood sugar and postprandial blood sugar are particularly critical. If you want to better and stable control of blood sugar levels, you must timely monitor various indicators, so that you can more effectively control blood sugar levels within a perfect range and prevent complications.
