How is a blood glucose tolerance test done? How do I check my glucose tolerance?

Glucose tolerance test, also known as OGTT, is a method of going to the hospital on an empty stomach in the morning to take 75g of glucose water orally (there is also a simple way to eat 2 taels of rice or steamed bread, which I think is inappropriate) and then taking venous blood tests every half an hour (to 2 hours) to determine whether it is diabetes, this method is currently the most accurate means of detecting (or excluding) diabetes. According to the current testing situation, the problem is not serious, and it is not too late to make amends, but it should be paid close attention. The blood sugar value is only a gap from the diagnostic criteria for diabetes, and glycosylated hemoglobin is high, indicating that the blood sugar has been high for at least 3 months, it is recommended to control the diet, strengthen exercise, and it is expected to return to normal within half a month, but you need to stick to it often, otherwise the risk of diabetes is very high.

OGTT testing is necessary, and if the test results prove that it is only a stage of insulin resistance and the islet function is not impaired, timely dietary control can prevent diabetes. Don't panic if you are diagnosed with diabetes, in your current situation, it is only mild, and diet control and exercise** can effectively control it.

1.For 3 days before the OGTT test, the diet should not be controlled, the daily carbohydrate content should not be less than 150 grams, and normal activities should be maintained.

2.Drugs that affect this trial (drugs that cause an increase or decrease in blood sugar) should be discontinued.

3.Patients should go 10-14 hours without food before the test.

4.On the morning of the day of the test, 300 ml of sugar water containing 75 grams of glucose was drunk within 5 minutes after fasting intravenous blood was taken, and intravenous blood was taken once 30 minutes, 1 hour and 2 hours after drinking sugar water, and urine was collected for urine glucose qualitative test. Do not smoke, drink coffee, tea, or eat throughout the trial, and sit quietly in a chair.

A glucose tolerance test can be done.

If the blood sugar level is between millimoles and liters 2 hours after drinking sugar water containing 75 grams of glucose, although it is not considered diabetes, it is also considered "impaired glucose tolerance", that is, the body's absorption and utilization of glucose is worse than that of a healthy person.

At this stage, there may not be the typical manifestations of diabetes, but it must not be taken lightly, because people with impaired glucose tolerance are the "reserve army" of diabetes and can be called "quasi-sugar friends".

It is mainly used to understand the body's ability to regulate blood sugar after ingesting glucose. This is a must-do test and one of the tests that expectant mothers often do during pregnancy. With this test, abnormal glucose metabolism can be detected at an early stage and diabetes can be diagnosed.

If some details are overlooked before the inspection, the results may be inaccurate.

Glucose tolerance is one of the items in the current prenatal examination, mainly in the pregnant woman 24 to 28 weeks of pregnancy to check whether the pregnant woman has diabetes, let me introduce the steps to you;

Water cup with powdered sugar.

To do glucose tolerance, we must do it in the morning, and we must not eat on an empty stomach, which means that we should not eat at 8 o'clock in the evening before doing sugar tolerance, until the next morning;

First of all, we will draw fasting blood once to check the fasting blood sugar, which is generally not higher for pregnant women;

Secondly, the doctor gave us glucose or powdered sugar, and we washed it with 250ml-300ml of water by ourselves, and then drank it in 5 minutes, and then after an hour, we went to draw the second blood;

After the second blood draw, it takes another hour that is, 2 hours after drinking the sugar water, after drawing blood, the whole process needs to draw blood 3 times, and wait for the result after drawing, the glucose tolerance process is roughly like this;

A glucose tolerance test can be done.

If the blood sugar level is between millimoles and liters 2 hours after drinking sugar water containing 75 grams of glucose, although it is not considered diabetes, it is also considered "impaired glucose tolerance", that is, the body's absorption and utilization of glucose is worse than that of a healthy person.

At this stage, there may not be the typical manifestations of diabetes, but it must not be taken lightly, because people with impaired glucose tolerance are the "reserve army" of diabetes and can be called "quasi-sugar friends".

It is mainly used to understand the body's ability to regulate blood sugar after ingesting glucose. This is a must-do test and one of the tests that expectant mothers often do during pregnancy. With this test, abnormal glucose metabolism can be detected at an early stage and diabetes can be diagnosed.

If some details are overlooked before the inspection, the results may be inaccurate.

Glucose tolerance testing is done to rule out gestational diabetes after pregnancy. It is at 24 weeks to 28 weeks of pregnancy, through blood sampling to test the blood sugar situation, and then preliminarily determine whether the patient has gestational diabetes, and sugar screening test, generally choose 50 grams of glucose powder dissolved in 200 ml of water, and then test the blood sugar value after one hour, if the blood sugar value is greater, then it means that the glucose tolerance test is abnormal. Eat lightly, get enough sleep, and be in a good mood.

Glucose tolerance is mainly used for the examination of diabetes, many female friends will have blood sugar rise due to various reasons after pregnancy, and then there may be diabetes, for expectant mothers with normal sugar screening results, there is no need to do a glucose tolerance test. However, for expectant mothers with a positive sugar screening result, a glucose tolerance test should be done to confirm the diagnosis of gestational diabetes. This disease can cause great harm to the physical health of the expectant mother and the normal development of the fetus.

You can go to the hospital in advance to ask, you need to be fasting, after the first blood draw, you need to eat a steamed bun or drink 75 grams of glucose, first go and ask if you need to prepare yourself.

The following points should be noted in the glucose tolerance test:

1. Within 3 days before the examination, the daily carbohydrate intake should not be less than 150g.

2. Stop taking drugs that may affect OGTT for 3 7 days before the examination. Common examples of such drugs are contraceptives, thiazide diuretics, phenytoin, glucocorticoids (dexamethasone, prednisone, etc.), receptor antagonists (propranolol, metoprolol, etc.).

3. Generally, it is required to fasting 12 hours before the glucose tolerance test, and then eat normally for three days before the glucose tolerance test, but do not eat and drink so as not to interfere with the results; In addition, on the morning of glucose tolerance, you come on an empty stomach and you should not come too late, because you come too late and your fasting time is too long, which will also affect its fasting blood sugar results. Then drink 75 grams of sugar, it is best to drink 100-200 ml of water when drinking sugar, slowly drink it within 5 minutes, and then measure blood sugar once an hour, and measure blood sugar once every two hours.

Glucose tolerance during pregnancy is to draw blood, you can't drink water after 10 o'clock in the evening before the examination, draw two tubes of blood on an empty stomach the next morning, and then drink glucose water immediately (it is recommended to go to the hospital one day in advance to open the examination list of sugar screening, and the hospital will give you a pack of glucose after paying the money, and prepare it with 200-300 water at home on the day of the examination), and then draw the second time after drinking the glucose water, and then draw the third time in an hour to end, before the end of the three blood draws, in addition to drinking glucose water after the first draw, No more water and breakfast.

If the results of the sugar screening for pregnant women show that they are at high risk, the doctor will generally recommend that they continue to do one.

Glucose tolerance test (glucose tolerance test) to confirm the presence of gestational diabetes.

It is recommended to perform a 75g formal glucose tolerance test at 24-28 weeks of pregnancy to monitor blood glucose levels on an empty stomach and 1 hour and 2 hours after drinking sugar. Gestational diabetes can be diagnosed if any one of the 3 items meets or exceeds the limit value, i.e., fasting blood glucose and blood glucose at 1 hour and 2 hours after taking sugar, respectively.

Be sure to fasting for eight hours and water for more than four hours, take glucose orally, take it according to the prescribed amount in the strict sense, pay attention to your own cleanliness and hygiene, and avoid drinking too much water, because it will affect the results of the test.

Down's screening is a test to detect the presence of malformations in the fetal neural tube, and a "positive" screening result indicates that the screening result is abnormal, and pregnant women have a higher chance of having a child with DS or NTD, which is a high-risk group and needs to be further diagnosed. A "negative" screening result indicates that the screening result is normal, and the chance of pregnant women having a child with DS or NTD is low, but not equal to zero, and is in a low-risk group. High-risk people need to have a chromosomal (amniocentesis) to confirm the diagnosis.

I wish you and your baby good health.

Mainly to check for gestational diabetes.

Fasting oral glucose tolerance test (OGTT) [glucose tolerance]: At least 3 days before the test, the patient's diet and activities are not restricted, the test is conducted in the early morning, after fasting for 12 hours, venous blood is taken to measure fasting blood glucose, and then 75 grams of glucose powder is dissolved in 300ml of water for 5 minutes and drunk. Blood glucose concentrations were measured at three time points after taking sugar.

Eating, drinking and smoking are prohibited throughout the examination.

Abnormal glucose metabolism in pregnancy is a common pregnancy comorbidity, which can be divided into two states: gestational diabetes mellitus (GDM) and impaired glucose tolerance during pregnancy (GIGT).

GDM is the test to confirm gestational diabetes.

GIGT refers to a stable change in blood glucose in the early stages, but the measured values are intermediate or excessive between normal and abnormal. That is, it is not a completely healthy state.

However, gestational diabetes or abnormal glucose metabolism during pregnancy will be harmful to both mother and baby, and may cause miscarriage, gestational hypertension, infection, polyhydramnios, ketoacidosis and premature birth, so mothers should still pay attention!

To check the ability to suction sugar, it is to check for hyperglycemia and diabetes during pregnancy.

Down's screening is mainly for Down syndrome, mainly to check whether the baby will be born stupid Down's baby, then, while sugar screening is to check gestational diabetes, mainly to check the blood sugar status of the expectant mother. What is the content of the Tang Screening Examination? What does a sugar sieve mainly check?

What is the content of Tang screening Tang screening is mainly for the screening of Down syndrome, that is, to check whether the baby will be a congenital stupid Down's child, mainly to check alpha-fetoprotein, human chorionic gonadotropin, and free estriol.

The main purpose of doing a glucose tolerance test is to determine whether you have diabetes, etc. If your blood sugar level is elevated, this test is usually done, and a normal blood sugar level is usually not required. Pregnant women may have abnormal glucose tolerance after pregnancy.

If blood sugar can be controlled within a certain range with aggressive dietary control, it can be used to check for gestational diabetes or abnormal gestational glucose tolerance.

Progesterone during pregnancy will inhibit the secretion of insulin, and some people will develop gestational diabetes if they suppress it too much, which will endanger the health of the fetus if it is not timed. Nowadays, more and more pregnant women are suffering from gestational diabetes, and glucose tolerance testing is to screen for gestational diabetes.
