From measuring blood sugar to correct selection of hypoglycemic drugs

Measuring blood sugar is an important means for diabetic patients to monitor their condition.

However, many diabetic friends do not know whether to take hypoglycemic drugs when testing blood sugar, and the wrong choice to stop the drug, resulting in inaccurate test results.

So how do diabetic friends correctly detect blood sugar, and how to choose the right hypoglycemic agent based on the detected blood sugar results?

銆€銆€When measuring the blood sugar on the same day when the diabetes friend stops the medicine, it is necessary to take the usual medicine.

Because the purpose of the test is to understand the control of the patient’s blood sugar during the medication, if the drug is stopped on the day of the test, it will lead to blood sugar changes, so that the blood glucose test results can not accurately reflect the true level of blood glucose during the treatment.

Moreover, stopping the drug will make the condition repeat or aggravate.

銆€銆€In addition, the medication time and meal time should be relatively fixed, to avoid adverse effects on treatment and normal meals due to blood tests.

銆€銆€Because a large number of hypoglycemic drugs should be taken after meals, therefore, go to the hospital in the morning to measure fasting blood glucose, which has certain effects on medication and meals. Pay attention to the following situations: First, for patients taking hypoglycemic drugs, when testing fasting blood glucose,If the blood collection time is late, the amount of noon should be reduced as appropriate to avoid hypoglycemia caused by two drugs. Second, patients who are treated with regular pre-mixed insulin in the morning can take a short injection before eating.Insulin; third, for the use of intermediate-effect insulin before going to bed, the effect can be maintained until the next morning at 8 or 9 o’clock, so the detection of fasting blood glucose collection time allows a little later; fourth is the low insulin secretion level, the presence of early morning high blood sugarPhenomenon patients, it is best not to go to the hospital to check fasting blood sugar, because the hospital blood collection time is late, will delay the misdiagnosis of patients before the insulin injection, adversely affect the blood sugar throughout the day.

銆€銆€According to the determination of fasting blood glucose, it is a simple and convenient method to select hypoglycemic drugs according to the fasting blood glucose.

If the fasting blood glucose is less than 7.

0 mmol / liter, first replace the drugs that do not cause hypoglycemia: metformin (German), acarbose (by sugar).

If the patient is mainly hyperglycemia after meal, it is more suitable to take acarbose (by sugar).

At the beginning of the treatment, a medium dose can be used: metformin (German) at 250-500 mg twice a day, or acarbose (by sugar) at 25 mg each time, 3 times a day.

銆€銆€If the fasting blood glucose is 7.


1 mmol / liter, if the body weight is normal or thin, a small dose of sulfonylurea hypoglycemic agents, such as glipizide controlled release tablets (Rui Ning) 5 mg or glimepiride 0 can be used.

5-2 mg, once a day, or gliclazide (40 mg) twice a day; if too much, suitable for replacing metformin (German), daily1500-2500 microns, taken in 3 divided doses.

If the fasting blood glucose exceeds 11.

1 mmol/L, the choice of the drug is the same as above, but the amount needs to be appropriately increased: glipizide controlled release tablets (Rui Ning) 5-10 mg daily, or glimepiride 4 mg daily, orLezit (Dacom) is 160 mg daily, or metformin (German) is 1500-2500 mg daily.

When extracting thiourea hypoglycemic drugs, be alert to hypoglycemia.

If blood sugar is higher, insulin should be injected.

銆€銆€The use of hypoglycemic drugs is particular.

Please pay attention to the time of taking the hypoglycemic agent. Only when you take the medicine on time can you achieve the best effect.

Sulfonylureas should be taken before meals because food can affect the absorption of the drug and the time it takes for the drug to work. It is usually taken 15-30 minutes before meals.

The biguanide can be taken before or during the meal. If there is a rehabilitation reaction, it can also be taken after the meal, and the sugar should be chewed with the first meal.
