There are many sugar lovers say, my blood sugar how to test are high, careful inquiry, found that each time the day before the test blood sugar, will stop using hypoglycemic drugs. The fact is that it is not advisable to stop the medication, either for fasting blood sugar or postprandial blood sugar. When testing fasting blood glucose, the glucose-lowering drugs (including insulin) of the first night should be applied as usual; when testing blood glucose two hours after a meal, it is appropriate to apply the medication of the current meal as usual. As a diabetic, the purpose of the test is to find out how well the blood sugar is controlled under medication. Stopping medication to test blood glucose, instead of accurately reflecting the true condition, can cause blood glucose fluctuations and lead to aggravation of the condition. So that said, is it possible to reduce the test? Some sugar users will intentionally eat less the day before the test, this is also inappropriate. Others consciously diet before the test, so that the measured fasting blood glucose results may be better, but also can not represent the real blood glucose level in the usual state. It should be noted that before the test, you should eat normal meals, avoid strenuous exercise, do not smoke, do not drink coffee and other stimulating beverages, so that the test results will be true and reliable.
