What is the glucose tolerance index during pregnancy? Is it necessary to check it?

If you want to be sugar-tolerant, you must first understand when it is best and why, so that you can talk about specific technological problems. So let's talk about when to do glucose tolerance first, and then talk about the process of doing glucose tolerance.

When is the best sugar tolerance? After pregnancy, in the early stage, the hormones secreted by the placenta will weaken the effect of insulin, so if you were in good health before, you generally wouldn't develop gestational diabetes from the beginning.

Pregnant women generally develop insulin resistance after 20 weeks. Since then, gestational diabetes has been in a high incidence period. Therefore, the glucose tolerance test is generally arranged in 24-28 weeks. I had a glucose tolerance test at 26 weeks.

Therefore, it is best to do glucose tolerance in 24-28 weeks. If the blood sugar was high in the past, the doctor would ask about the glucose tolerance in advance and follow the doctor's advice.

What is the process of making sugar tolerance? Regarding the process of glucose tolerance, each hospital may be different. Some hospitals have to draw blood four times, and some hospitals have to draw blood three times. Blood was drawn three times. Tell me about the process of glucose tolerance test I experienced.

1, fast

Don't eat or drink water after 10 the night before, and have an empty stomach for at least 8 hours. The longer the time, the smaller the chance of abnormal results.

Because the method of glucose tolerance test is to take venous blood and detect the content of glucose in blood, both food and water contain glucose, which will increase the blood glucose concentration and lead to abnormally high results.

2. Draw blood 1 time

After arriving at the hospital, it is generally necessary to queue up for inspection. In this case, you can communicate with the doctor in advance. First, open the test sheet and draw blood on an empty stomach for 1 time. This will save you more time and won't make you hungry for too long.

Step 3 drink sugar water

The doctor will prescribe a portion of powdered sugar, about 50g, and add the powdered sugar into 300ml warm water, which can be drunk after 5 minutes of melting. Don't drink too fast, just drink at a constant speed. Because sugar water is too sweet and greasy, it is delicious and a little difficult to swallow. Note that you must bring a big cup. I am embarrassed to bring a 200ml cup.

Some hospitals drink 75g powdered sugar and 200ml water, which is different. Just follow the requirements of the hospital

Step 4 draw blood for the second time

Start timing after drinking sugar water, and draw blood once every hour/kloc-0. When queuing, pay attention to explain to the doctor that it is glucose tolerance, and the doctor will give priority to blood drawing at the specified time.

Step 5 draw blood for the third time

Start timing when drinking sugar water, and draw blood once after 2 hours. At this time, the whole glucose tolerance test process is over, and we can finally sit down and eat something. Hungry for so long, you can replenish energy in time to avoid hypoglycemia.

The standard value of glucose tolerance is fasting blood glucose: 3.89-6.11mmol/L.

1 hour blood glucose: 10.6 mmol/L

2-hour blood glucose: 8.6 mmol/L.

There is no problem with this range. If the value is slightly deviated, it is recommended to recheck and confirm, sometimes there will be errors in the detection.

Which mothers must be pregnant mothers with abnormal glucose tolerance and obesity, pregnant mothers with excessive weight gain, pregnant mothers over 30 years old, pregnant mothers with gestational diabetes, pregnant mothers with large fetuses or intrauterine death or stillbirth with a huge family history of diabetes, because these types of mothers have the highest probability of suffering from gestational diabetes, so don't forget to have a glucose tolerance test on time. Some friends also asked, "I am healthy, can I not tolerate sugar?" I think it is better to do it. I'm in good health, too. I've had a glucose tolerance test. It's not easy to get pregnant once. It will make me feel more at ease if I can rule out the risk.
