Glucose tolerance test is an important examination
for diabetic patients, and there are many points to pay attention to before and during the test.
Before
the experiment, special attention should be paid to diet. Normal and stable diet should be maintained for 3 days before the test. The daily carbohydrate intake should be between 150 and 300 grams, and the staple food should not be increased or decreased at will. You must fast for 10-12 hours before the test, but you can drink a little water, but you should avoid sugary drinks. At the same time, if you are taking drugs that may affect blood sugar, such as glucocorticoids, thiazide diuretics, etc., you should tell your doctor in advance that diabetic patients who use insulin or oral hypoglycemic drugs should listen to the doctor’s arrangement to adjust their medication, and should not stop taking drugs at will, otherwise abnormal blood sugar may occur. In addition, strenuous exercise should be avoided as far as possible three days before the test. Normal activities such as daily walking are no problem, but high-intensity exercise such as running and fitness should be prohibited, because strenuous exercise may cause excessive blood sugar consumption and affect the test results.
Glucose intake should be accurate during the
test. Generally, 75 grams of anhydrous glucose or 82.5 grams of glucose powder containing one molecule of water are dissolved in 250-300 milliliters of warm water and drunk within 5 minutes. Diabetics should not drink too fast or too slowly, nor should they mistake the amount of glucose. Blood collection time should also be strictly controlled. Fasting blood glucose value should be collected before oral glucose, and then blood glucose should be collected 30 minutes, 1 hour, 2 hours and 3 hours after oral glucose. Diabetic patients should keep quiet in the test, do not smoke and do strenuous activities, sit quietly in a chair and rest, so that the body can naturally respond to glucose. Because smoking and strenuous activity can accelerate blood circulation and metabolism, and then affect the results of blood sugar measurement.
Diabetic patients should strictly follow the requirements before and during the glucose tolerance test, so as to get accurate and reliable test results, and provide a strong basis for doctors to further diagnose and adjust the treatment plan.
