Glucose tolerance, in layman's terms, is to check the body's ability to tolerate the glucose ingested. It is to check the pregnant woman herself.

If your blood glucose is between 7.8 and 11.1 mmol/L two hours after drinking 75 grams of glucose, you are not considered a diabetic, but you are still considered to have "impaired glucose tolerance," which means that your body absorbs and utilizes less glucose than a healthy person.

If a pregnant woman's glucose screening results show a high risk, her doctor will usually recommend a glucose tolerance test to confirm whether she has gestational diabetes.

Causes of bias in oral glucose tolerance test results:

1, dietary Factors:

Before the glucose tolerance test, if the diet is excessively restrictive and the intake of carbohydrates is too small, then the glucose tolerance will be found to be reduced, and the test results will be false-positive.

2. Exercise factor:

Strenuous exercise before the test can also affect the test results. Although exercise can accelerate glucose utilization and lower blood glucose; however, more strenuous exercise will excite the sympathetic nerves and cause an increase in the secretion of some glucagon (e.g., cortisol), which will raise blood glucose.

3, mental factors:

Emotional excitement can also make the sympathetic nerves excited, glucagon secretion increased, blood glucose rise, affecting the test results. Therefore, it is important to keep your mind calm and emotionally stable during the test.

4.? Disease factors:

Endocrine diseases such as hyperthyroidism or vomiting, diarrhea and other conditions when the blood sugar will be affected. Therefore, it is not suitable to do the glucose tolerance test in the state of illness.

5, stress factors:

such as trauma, infection, acute illness, surgery and other stressful conditions, blood glucose may also rise, during which it is not suitable for glucose tolerance test.

6, drug factors:

Glucocorticoids, certain antihypertensive drugs and other drugs can affect blood sugar, making it rise, fall or fluctuations. But you can't stop taking them without authorization in order to rule out the effect of drugs on blood sugar.
