How to check sugar sieve
Sugar screening (glucose screening) is an important test during pregnancy and is used to screen for gestational diabetes mellitus (GDM). Gestational diabetes can have adverse effects on maternal and fetal health, so early screening and intervention are crucial. The following are details about sugar screening examinations, including examination procedures, precautions and related data.
1. The purpose of sugar screening test
The main purpose of sugar screening is to screen pregnant women for gestational diabetes. Gestational diabetes may lead to problems such as fetal enlargement, dystocia, and neonatal hypoglycemia, so early detection and management are very important.
2. Time for sugar screening examination
Sugar screening is usually done between 24-28 weeks of pregnancy. For pregnant women who are at high risk (such as obesity, family history of diabetes, previous history of gestational diabetes, etc.), doctors may recommend early screening.
3. The process of sugar screening examination
The sugar screening test is divided into two steps: preliminary screening (50g glucose challenge test) and confirmatory test (75g or 100g glucose tolerance test).
| steps | Check content | Things to note |
|---|---|---|
| 1. Initial Screening | Drink 50g glucose solution and measure blood sugar 1 hour later | No need to fast, results ≥7.8mmol/L require further examination |
| 2. Diagnostic examination | Drink 75g or 100g glucose solution on an empty stomach, and measure fasting, 1 hour, and 2 hour blood glucose. | Fasting is required for 8 hours. If any value exceeds the standard, GDM can be diagnosed. |
4. Precautions for sugar screening examination
1.Diet control:Maintain a normal diet 3 days before the examination and avoid deliberately reducing carbohydrate intake.
2.Fasting requirements:Fasting is required for 8 hours for the confirmatory examination, and fasting is not required for the preliminary screening.
3.Avoid strenuous exercise:Avoid strenuous exercise during the examination to avoid affecting blood sugar results.
4.Follow your doctor’s advice:If you have special circumstances (such as vomiting), you need to inform your doctor in time.
5. Interpretation of results of sugar screening test
The normal range of sugar screen results varies depending on the test method. The following are common standards:
| Check type | normal range | Exception range |
|---|---|---|
| 50g glucose challenge test | <7.8mmol/L | ≥7.8mmol/L |
| 75g glucose tolerance test | Fasting <5.1mmol/L, 1 hour <10.0mmol/L, 2 hours <8.5mmol/L | Any value exceeds the standard |
6. Dangers of gestational diabetes
If the sugar screen result is abnormal and gestational diabetes is diagnosed, it may have the following effects on the health of the mother and baby:
1.For pregnant women:Increases the risk of gestational hypertension, premature birth, and cesarean section.
2.For the fetus:It may lead to problems such as macrosomia, neonatal hypoglycemia, and jaundice.
7. Management of gestational diabetes
If gestational diabetes is diagnosed, the following measures need to be taken:
1.Diet modification:Control carbohydrate intake and increase dietary fiber.
2.Movement:Proper exercise helps control blood sugar.
3.Blood glucose monitoring:Monitor blood sugar regularly and treat with insulin if necessary.
8. Summary
Sugar screening is an important examination during pregnancy, which can detect gestational diabetes in time and take intervention measures. Pregnant women should follow the doctor's advice for regular examinations, and pay attention to the diet and fasting requirements before the examination. If you are diagnosed with gestational diabetes, you need to actively cooperate with your doctor in management to ensure the health of mother and baby.
