What is the process of glucose tolerance? What is the purpose of glucose tolerance?

Introduction: As we all know, women during pregnancy must go to the hospital regularly for prenatal checkups. There are many items for prenatal checkup, one of which is called glucose tolerance test, so what is the process of glucose tolerance? What is the purpose of glucose tolerance? Let's find out together today.

Don't eat anything after 10 o'clock the night before doing glucose tolerance, don't drink water, and ensure eight hours of fasting before the test, the longer the fasting time, the more accurate the test result, because the glucose tolerance test method is a venous blood draw to test the glucose content in it, and food and water contain glucose, which will affect the test results. When I arrived at the hospital, I went to the doctor to prescribe a laboratory test and draw blood on an empty stomach.

At this point, the doctor will give a packet of about 50 grams of powdered sugar, add it to warm water, stir it to dissolve, and it must be drunk within five minutes. Sugar water is relatively sweet and greasy, but the average person can drink it, and some hospitals do not prepare disposable cups for pregnant women, so it is best for pregnant women to prepare a cup and bring it with them. Blood is drawn once an hour after drinking sugar water, and once every second hour and third hour, at which point the glucose tolerance test process is completed.

After 20 weeks of pregnancy is the peak period of gestational diabetes, so pregnant women should have a glucose tolerance test around 24 weeks. The purpose of glucose tolerance is mainly to determine whether pregnant women have gestational diabetes, to find out whether there is any abnormality in blood glucose metabolism in time, and to give intervention if there is any abnormality**. If gestational diabetes is severe, dystocia may occur.

From the second trimester of pregnancy, the effect of insulin on pregnant women will be greatly reduced, so it is easy to raise blood sugar, if the blood sugar level does not come down, the fetus is prone to hypoxia, causing dystocia, macrosomia or stillbirth and other serious consequences. If the glucose tolerance test is abnormal, medications** or insulin** can be used, and pregnant women should exercise moderately, eat a balanced diet, and stabilize the blood sugar range at a normal value.

The purpose of blood collection is to determine whether pregnant women have diabetes and hyperglycemia by taking a blood test on an empty stomach, dissolving glucose in water and drinking it.

When you are about 34 weeks pregnant, you can do glucose tolerance. To do glucose tolerance, you need to go to the hospital on an empty stomach, find a doctor to write a good list, go to the blood drawing department, the doctor will adjust the glucose solution, drink it in one go, and draw blood every 40 minutes, an hour, or two hours to see the blood sugar value. This is done to prevent gestational diabetes from causing problems such as gestational diabetes, neonatal high blood sugar, and macrosomia due to high blood sugar in pregnant women.

The process of glucose tolerance is as follows: mix a packet of glucose powder into 500 ml of water, drink it slowly within 20 minutes, then draw blood for testing after an hour, conduct a second test after an hour, and conduct a third test after the third hour; The purpose of glucose tolerance is to prevent hyperglycemia during pregnancy.

1. Preparation before meals:

Before a glucose tolerance test, meal preparation is usually required. Your doctor will ask you to start fasting the night before, usually for 8 to 12 hours, and drink only water.

2. Measure fasting blood glucose:

On the day of the test, you will be asked to go to a hospital or clinic on an empty stomach. Your doctor will take a small portion of your blood to measure your fasting blood sugar level.

3. Drink glucose solution:

After fasting blood glucose measurements are as high as they are high, you will be asked to drink a glass of glucose solution containing a specific dose. It is usually a 75 g glucose solution taken orally.

4. Time observation:

After drinking the glucose solution, you will need to wait for a period of time (usually 2 hours) at a hospital or clinic where you will not eat or drink and only sit still or do light activity.

5. Measure blood sugar

After the waiting time is over, the doctor will draw a small portion of the blood again to measure the blood sugar level. This will help your doctor determine how well you can metabolize glucose. <>

The glucose tolerance test requires an oral glucose tolerance test at the time of the procedure and eating the night before.

Glucose tolerance test is usually used to determine whether there are symptoms such as gestational diabetes, dizziness during the test, trying not to eat at night, so as not to affect the accuracy of the test results, and oral glucose tolerance test is required. First of all, you need to draw blood on an empty stomach, generally after 5 minutes, you need to take glucose, after drinking glucose, generally in about an hour, you need to draw venous blood again, and then wait for the test results, it is recommended to operate in a regular hospital.

In daily life, try not to eat foods high in sugar and eat a nutritious and balanced diet.

1.The day before doing glucose tolerance, don't eat anything after 10 o'clock, don't drink water, and make sure to have an empty stomach for eight hours before the test, the longer the fasting time, the more accurate the test results.

2.When I arrived at the hospital, I went to the doctor to prescribe a laboratory test and draw blood on an empty stomach.

3‎.The doctor will give a packet of about 50 grams of powdered sugar, add it to warm water, stir it up, and drink it within five minutes. Sugar water is sweet, but the average person can drink it, and some hospitals do not prepare disposable cups, so it is best to prepare a cup to bring with you.

4.Blood is drawn once an hour after drinking sugar water, and once every second hour and third hour, at which point the glucose tolerance test process is completed.

If you want to control sugar, you should usually pay attention to eating small and frequent meals, eat more staple foods rich in dietary fiber, replace white rice with grains, or choose whole wheat bread and steamed bread. Avoid high-sugar foods, and when eating fruits, it is best to choose fresh fruits with low sugar content, and avoid fried and fried foods.

During pregnancy, mothers need to do a variety of different examinations according to different months, which can not only ensure that the mother's body is in a healthy state, but also ensure that the child is fully developed in the womb. Glucose tolerance is a glucose tolerance test, which can find out whether the pregnant mother has diabetes, after all, if you suffer from diabetes during pregnancy, it can not only affect the normal development of the child, but also cause great problems in the later production. <>

Before deciding to do glucose tolerance, the mother must keep 8 to 10 hours of fasting, not only can not eat some food, water is absolutely not drinkable, go to the hospital on the 2nd day to draw a small amount of plasma glucose, and then some anhydrous glucose powder under the guidance of the doctor, dissolve in water and stir well, you need to drink it within 5 minutes, and you must remember exactly when to drink the first sip of glucose water. Based on this, take plasma glucose every half an hour, one hour, two hours, and three hours, and you can't eat anything in the middle of the blood draw, so that the glucose tolerance is done, and you can just wait for the results. <>

The reason why it is necessary to check whether the pregnant woman has diabetes is because if the pregnant woman has diabetes during pregnancy, then the risk of miscarriage will increase, and there is a risk of infection with gestational hypertension, and if you have a caesarean section, the chance of postpartum hemorrhage will be relatively much higher. In addition, there are some pregnant women whose urinary system will be infected, and the most important thing is that some high sugar in the pregnant woman's body will also be absorbed by the baby, which is easy to produce macrosomia, fetal malformations, not to mention premature birth, the most worrying thing is that the fetus will be restricted during growth, so it is very necessary to do glucose tolerance. <>

Pregnant mothers do not need to be too anxious during pregnancy, they need to follow the doctor's instructions, go to some relevant examinations, pay more attention to their diet, do not eat more high-sugar foods, and appropriate exercise can also effectively alleviate the appearance of gestational diabetes.

Glucose tolerance test method: Oral glucose tolerance test Purpose: To determine whether there is gestational diabetes.

What to check: 75 grams of glucose tolerance screening. Check Preparation:

Eat normally for three days before the test, and fast after dinner on the day before the test until the morning of the test day, that is, you cannot eat or drink after 7 p.m. the night before the blood draw. Examination method: A total of 4 blood draws, and one fasting blood draw.

Pregnant women do glucose tolerance tests to confirm whether they have diabetes, which can affect the normal development of the fetus. If there is gestational diabetes, the incidence of miscarriage, gestational hypertension, polyhydramnios, surgical birth (referring to caesarean section), birth trauma and postpartum hemorrhage is relatively high, and urinary tract infections are also more common. Patients with gestational diabetes mellitus have significantly higher rates of fetal macrosomia, fetal malformations, preterm birth, and fetal growth restriction.

Glucose tolerance test is a test used to check for gestational diabetes and is done between 24 and 28 weeks of gestation. Since the test needs to be done on an empty stomach, it is necessary to ask your doctor to prescribe a laboratory test in advance.

Eat less sweets 2 days before the examination. Fasting after 10 o'clock in the evening before the examination, abstaining from drinking after 12 o'clock, fasting blood sugar in the hospital on the morning of the examination, drinking sugar water containing 75 grams of glucose powder, sugar water should be drunk at one time within 5 minutes, and blood was drawn for 1 hour and 2 hours after drinking sugar water for 1 hour postprandial blood sugar and 2 hours postprandial blood sugar respectively.

The test results are generally available in 1-2 days.

The process of doing glucose tolerance is that before that, we have to draw blood, and then drink a large glass of sugar water and then draw blood, which is to check if we have diabetes.

Glucose tolerance test: Oral glucose tolerance test Objective: To determine whether gestational diabetes is present. Check contents: Glucose tolerance screening grams. Test preparation: Eat normally for three days before the test, and fast after dinner before the test until the morning of the test day, that is, the night before the draw.

1. Glucose tolerance is the abbreviation of oral glucose tolerance test, and venous blood is drawn on an empty stomach to measure blood glucose, and insulin can be measured at the same time.

2. After fasting blood drawing, add 75g of glucose to 200-300ml of water, if it is glucose powder, drink it within 5 minutes. The timing starts from the first sip of sugar, and blood is drawn to measure venous blood glucose 1 hour and 2 hours after taking sugar, and insulin can be measured at the same time.

3. In a few cases, glucose tolerance that needs to be extended can continue to measure blood glucose for 3 hours.

4. Pay attention to the daily carbohydrate of not less than 150g for 3 days before glucose tolerance, do not eat other foods containing calories during the glucose tolerance test, do not recommend strenuous activities, but do not need to stay in bed, and prohibit smoking, coffee and other factors that affect blood sugar.
