Two-hour glucose tolerance test in pregnant women

Glucose tolerance in pregnant women is a common problem during pregnancy, mainly because it is more likely that sugar is not fully absorbed during pregnancy. Therefore, it is recommended that everyone should understand how to deal with glucose tolerance in pregnant women. When a pregnant woman has a two-hour high glucose tolerance problem, it is recommended that she should avoid consuming sugar and exercise more, which can effectively prevent high blood sugar levels.

During pregnancy, we have to do many prenatal examinations of all sizes. One of them is for gestational diabetes, called "sugar screening". It is only one letter different from the other "Down syndrome screening" and is often confused. Sugar screening tests help detect abnormalities as early as possible and take further measures to help pregnant women safely through the pregnancy. What should be done if a pregnant woman’s 2-hour glucose tolerance test is high? Let’s talk specifically about this topic below.

Blood glucose measurement 2 hours after a meal is another important method for diagnosing and detecting diabetes. Clinically, there are many patients whose fasting blood sugar is not high, but their blood sugar increases significantly 2 hours after a meal, and they can also be diagnosed with diabetes. The method is to eat a 2-liang (about 100-gram) steamed bun or 75 grams of glucose in the morning on an empty stomach, and then draw blood to measure blood sugar 2 hours after the meal. If the plasma blood sugar is greater than or equal to 200 mg/dL (11.1 mmol/L), it can be diagnosed as diabetes even if the fasting blood sugar is normal. If the result is <140 mg/dL (7.8 mmol/L), diabetes can be ruled out. If the result is >140mg/dL (7.8mmol/L), a further 75g oral glucose tolerance test is required to make a diagnosis.

A 2-hour post-meal blood sugar test is actually a simplified glucose tolerance test. Because this method requires fewer blood draws than the oral glucose tolerance test, is simple and easy to perform, and is easily accepted by patients, it is the most commonly used method in clinical practice to screen and detect diabetic patients with normal fasting blood sugar. Measuring blood sugar 2 hours after a meal has two meanings: one is for diagnosis, and the other is to observe the recovery of glucose tolerance, thereby reflecting the functional status of the pancreas. If after a period of treatment, fasting blood sugar has returned to normal, but postprandial blood sugar is still high, it often indicates that the patient's glucose tolerance is still poor and insulin secretion is still delayed. If fasting blood sugar is normal and postprandial blood sugar is also normal, it means that the patient has better glucose tolerance and improved pancreatic islet function.

High glucose tolerance means that the pregnant woman’s ability to metabolize sugar is not very good, which is a situation that many pregnant women encounter today. If your test results are the same, please don't be too discouraged. You must follow the doctor's instructions, strictly control your diet, and maintain a positive and happy mood, and you will definitely get through the entire pregnancy smoothly.
