Glucose tolerance is a glucose tolerance test. Exercise during the glucose tolerance test may affect the results. During the glucose tolerance test, you should not do strenuous exercise, otherwise it may lead to inaccurate results and not truly reflect the patient’s blood glucose. In addition to not doing strenuous exercise, you should also be careful not to smoke, drink alcohol, coffee and tea and other beverages. Discontinue medications that may affect the glucose tolerance test before the test, such as birth control pills, diuretics or phenytoin sodium, and it is recommended to discontinue the medication for 3 to 7 days if the condition permits. If you need to do glucose tolerance test, it is recommended to consult with a professional doctor for detailed precautions and strictly follow the doctor’s instructions for preparation, so as not to affect the test results.
