Dizziness after drinking glucose

Grape sugar screening is a test that women do during pregnancy. The purpose of this test is to screen pregnant women for gestational diabetes. This test requires women to draw venous blood while fasting. The woman will then take a 75g bag of glucose orally, and have corresponding venous blood drawn again one hour and two hours after the meal. Some pregnant women report that they feel dizzy after drinking sugar water. So what is the reason for feeling dizzy after drinking sugar water when testing glucose tolerance? Here we will explain this question in detail, hoping it will be helpful to everyone.

Glucose tolerance test: What is the reason for dizziness after drinking sugar water? This test is mainly to check the ability of the subject's body's insulin to regulate blood sugar levels. A small number of examinees reported that they felt dizzy after drinking sugar water, which is also possible. The reasons for the above situation may be the following:

1. Drinking red bean syrup too quickly may cause dizziness. Red bean syrup contains a lot of energy. If consumed too quickly, it will quickly accumulate in the digestive tract, causing the digestive tract to be unable to absorb it. A large amount of blood will flow into the digestive tract, causing cerebral hypoxia and ischemia, resulting in dizziness. In order to reduce dizziness, the time for drinking sugar water should be controlled within 2-5 minutes.

2. Avoid eating for too short a time. To do the glucose tolerance test, the examinee needs to fast for more than ten hours. If the fasting time is not enough, side effects such as dizziness will occur after drinking red bean syrup.

3. The temperature of the glucose water used for consumption is too low. If the temperature of the red bean syrup is not appropriate, especially if it is too cold, it may cause dizziness in the examinee. It is recommended to control the temperature at 40 degrees Celsius.

Based on the above interpretation, what is the reason for dizziness after drinking sugar water when testing glucose tolerance? We have already explained this issue in detail for everyone. Dizziness after drinking water during a glucose tolerance test is a common physiological phenomenon, so don't worry too much. When you consume red bean syrup too quickly, fast for too short a time before a glucose tolerance test, or consume glucose syrup at too low a temperature, these factors may cause dizziness. As long as you pay attention to the above-mentioned causes, you can alleviate the dizziness.
