Glucose Tolerance Test Preparation

Glucose tolerance test preparation Glucose Tolerance Test - What is it for?

Preparing for the glucose tolerance test

Glucose tolerance tests are usually done in the morning. It is important that you appear perfect for the test. On the one hand, this means you should avoid nicotine, alcohol, coffee and tea twelve hours before the test starts.

This means you should not eat or drink anything except water for about ten hours before the test. To get reliable results, the German Diabetes Society recommends that you maintain your eating habits as usual at least three days before the start of the test, so as not to change them: So, do not follow any diet to positively affect the test results. It will only falsify the test results! After all, take more than 150 grams of sugar per day.

Glucose tolerance test method

First, blood is taken from veins, fingers or ears to determine your fasting blood glucose. You will then be given a sweet liquid, which you must drink in less than 5 minutes. This liquid contains 300 grams of glucose in 75 to 250 ml of water. After two hours, the blood is taken again and your blood sugar level is determined.

Evaluation and quality assurance

During the evaluation of the glucose tolerance test, the value of sugar after two hours of own blood was compared with the value after two hours. If one's own blood sugar level is too high, it indicates that the body cannot use enough blood sugar (glucose) and / or glucose cannot be absorbed into the cells in sufficient quantity. This can be due to a problem with insulin metabolism - such as diabetes mellitus.

The blood sugar levels responsible for lowering insulin or the values ​​for the absorption of blood sugar in the cells are listed below: Fasting Blood Sugar: With Blood Sugar After 120 Minutes: Glucose Tolerance Test should be tested in a sense, especially for those with impaired blood sugar. Raising blood sugar levels refers to diabetes. But what is diabetes and how do you recognize it?

Healthy: <100 mg (<5.6 mm / L)

Disturbed Blood Sugar Metabolism: 100 - 125 mg / dL (5.6 to 6.9 mm / L)

Diabetes mellitus: from> 125 mg / dL (> 6.9 mm / L)

Healthy: <140 mg (<7.8 mm / L)

Disturbed Blood Sugar Metabolism: 140 to 199 mgdl (7.8 to 11 mm / L)

Diabetes mellitus:> 199 mgdl (> 11 mm / l)
