Walk on an empty stomach on the day of glucose tolerance;
1. Reduce the intake of starch (pasta) and sugar two weeks before examination. Eat as little staple food as possible, and it is best not to drink rice porridge in the morning. You can use milk instead.
2. Don't eat high-fat food, and try not to eat sugary food. The sugary food here refers to sweets, drinks and even fruits that contain refined sugar and can be directly absorbed by the human body without any transformation, such as cola, litchi, sugarcane and a large number of watermelons. Fruits should be limited, especially fruits with high sugar content (fruits should be changed to fruits with low sugar content such as kiwi fruit, cucumber and tomato). Eat between meals). Don't put eggs in dinner.
3. Eat more vegetables, not less than 500 grams a day, and supplement vitamins and cellulose.
4. Drink plenty of water and exercise moderately. Walking after meals consumes too much sugar.
Don't eat and drink less water after 8 o'clock the night before yesterday.
6. Don't drink powdered sugar too fast. Drink slowly, little by little. Don't drink it all at once Drink within 3-5M.
7. Grasp the blood drawing time and drink it after one hour.
Glucose tolerance test is to check whether pregnant women have gestational diabetes. Under normal circumstances, expectant mothers with positive sugar screening results should do a glucose tolerance test to confirm whether they have gestational diabetes. Gestational diabetes means that expectant mothers do not have diabetes before pregnancy, but after pregnancy, due to various reasons, blood sugar may rise and lead to diabetes.
The glucose tolerance test during pregnancy must be completed within a certain period of time, and it will affect the test results too early or too late. At present, it is generally recommended to carry out glucose tolerance test at 24-28 weeks of pregnancy, because at this stage, the fetus has been formed and various organs have developed, which is the best time to observe the fetus.
Gestational diabetes mellitus (GDM) is harmful to both pregnant women and fetus, and it is very likely to harm the normal development of fetus, so we should pay attention to the examination of glucose tolerance. Glucose tolerance test is helpful to find problems during pregnancy in advance.
Precautions before glucose tolerance test are as follows:
1. Check the normal diet for the first three days.
Three days before the examination, pregnant women need a normal diet, and carbohydrates such as rice and pasta should not be less than150g. If the amount of staple food is deliberately reduced before the inspection, the inspection results will be wrong, leading to a wrong diagnosis.
2. Avoid strenuous exercise and maintain emotional stability.
Maintain normal physical activity for three days before the examination, but do not do strenuous exercise before the examination, because it will raise blood sugar. In addition, infection, trauma and violent mood swings can also excite sympathetic nerves, leading to errors in the results of glucose tolerance test.
3. Remember to eat on an empty stomach
In order to truly reflect the fasting blood glucose level, pregnant women need to fast for eight to fourteen hours when doing glucose tolerance test. For example, if you join a pregnant mother, you have to do a glucose tolerance test at 8 am. After the night before 10, stop eating, drink coffee, tea and other drinks, and only drink water.
Don't eat during the experiment.
Smoking, drinking and eating are not allowed during the inspection, and you can only walk around a little. Pregnant mothers need to stay calm and relaxed to avoid mood swings.
5. Special circumstances
If pregnant women have symptoms such as pallor, nausea and syncope during the examination, they must stop the examination immediately. If these symptoms appear three to four hours after eating sugar, it may be reactive hypoxemia, so it is necessary to draw blood immediately to measure blood sugar and let the patient eat.
It is not excluded that the results of glucose tolerance test are influenced by individual differences and other factors, and there may be errors. After the glucose tolerance test results come out, remember to guess at will and be sure to consult the doctor about the test results.
Now that the living standard has improved, as long as they eat normally, most pregnant mothers don't have to worry about nutritional problems during pregnancy; Even some pregnant mothers, under the meticulous care of their families, live a pregnant life with clothes to reach out for food. Then there is the protection of pregnant mother and fetus during pregnancy. In fact, if pregnant mothers don't pay attention, eat too much and don't exercise, and are used to brushing their mobile phones and watching TV at home, it will often lead to an imperceptible disease, that is, gestational diabetes. Gestational diabetes will have many adverse effects on pregnant mothers and fetuses, and it is easy to have miscarriage, premature delivery and macrosomia. Serious can threaten the life safety of pregnant women and fetuses. Therefore, pregnant mothers need to be screened for gestational diabetes during pregnancy, that is, the glucose tolerance test mentioned in the question, and a sugar screening test is needed before.
How to do glucose tolerance test? Expectant mothers need to do a sugar screening test first, and if the results are abnormal, they need to do a glucose tolerance test. Do you need to quit sugar and starch two weeks before the glucose tolerance test?
Before the sugar screening test, expectant mothers need an empty stomach 12 hours. Then the medical staff will dissolve 50 grams of glucose in 200 ml of water and let the expectant mother drink it in 5 minutes. Some hospital doctors give sugar to expectant mothers, let them drink it themselves and time it by themselves. From the first bite, after 1 hour, the venous blood of expectant mothers was taken for testing. If the expectant mother's result exceeds 7.8mmol/L, it may indicate that the expectant mother's sugar screening result is abnormal and further glucose tolerance test is needed.
Of course, some expectant mothers' sugar screening results exceed the standard, which is not necessarily gestational diabetes. Many of them are because expectant mothers eat too much sugar before sugar screening, such as candy, sweets and fruit, which leads to abnormal sugar screening results. Therefore, in the case of abnormal glucose screening results, a glucose tolerance test will be further arranged. Before the test, in order to make the test results accurate, it is necessary to control the diet, eat less sweets and fruits, and reduce the intake of starch staple foods two weeks before the test, and then conduct a glucose tolerance test.
Glucose tolerance test method: Before the test, the expectant mother needs to be on an empty stomach for 65,438+02 hours, first draw blood to check her blood sugar, then add 65,438+050 ml of 50% glucose in 65,438+000 ml of water, or dissolve 75 g of glucose powder in 300 ml of water, and the expectant mother will drink it within 5 minutes, and then drink it at 65,438+0 hours respectively. The normal indexes of glucose tolerance are: fasting 5. 1mmol/L, 0 hours later 10mmol/L, 2 hours later 8.5 mmol/L. If one of them exceeds the normal value, it can be diagnosed as gestational diabetes.
Therefore, it is not necessary to quit sugar and starch before the glucose tolerance test. In addition, most of our energy sources are provided by sugar and starch. If you don't eat sugar and starch for two weeks, your body can't stand it, and it will do more harm to your mother and fetus. In order to ensure the accuracy of the test results, we can reduce the intake of sugar and starch, and at the same time ensure the daily needs. Expectant mothers can't be kept in a state of lack of energy.
Several problems in glucose tolerance test.
You don't have to quit deliberately, you need a normal diet, so it is necessary to check your glucose tolerance. If you deliberately quit sugar for half a month and then check again, your blood sugar may be temporarily low, but that's the result of your cheating. At that time, doctors can't find the real problem and prescribe the right medicine, which is not good for themselves and the fetus. Of course, saying that you don't need to quit sugar deliberately doesn't mean you can eat too much sugar. It is best for pregnant women, especially in the third trimester, to strictly control sugar intake.
There is no difference between deliberately controlling diet and cheating in the exam two weeks before glucose tolerance! Normal glucose tolerance does not require abstinence from sugar and starch. Glucose tolerance is simply to determine whether pregnant women have gestational diabetes by detecting your blood sugar level. So if you deliberately give up starch and sugar, you are irresponsible for yourself. Because gestational diabetes is easy to give birth to giant babies, which is not good for children and women. I had it once when I was sugar-tolerant. Some pregnant women need to be tested again if the first test value is abnormal.
Sugar tolerance value
Generally, it can be done after 24 weeks of pregnancy, but it can't exceed 28 weeks at the latest. In fact, it is a mixture of glucose and water. It is said that sugar water is really disgusting, not the usual sweetness of candy. I was so scared that I threw up after drinking. But among different people, my sister came back with a second child and made it sugar-resistant. She actually thought the sugar water was quite delicious.
