There are always a lot of patients consulting their own blood glucose measurement, before and after the two differences, to the hospital and measured the results are still different, and there is no lack of many first diagnosis, young, obese type 2 diabetes patients. But no matter what type of diabetes, the correct detection of blood glucose is a very critical step, do not do a good job of the whole purpose of sugar control will be difficult to achieve. Below we will share with you the misunderstandings that often occur in the clinic, and we hope that sugar patients or their families can check themselves. 1, stop using glucose-lowering drugs before measuring postprandial blood sugar The purpose of checking postprandial blood sugar is to check the control of diabetes by drugs. If you stop taking the medication and measure your blood glucose, the results will not accurately reflect your condition, but will also cause fluctuations in blood glucose and even aggravate your condition. Therefore, in order to reflect the real situation of glycemic control of sugar users, and also to avoid the fluctuation of blood glucose caused by stopping medication, sugar users should use normal medication on the day of checking blood glucose. Excessive control of diet before checking In order to get the ideal value of blood glucose monitoring, some patients excessively control their diet before checking, at this time, the result of blood glucose measurement may be normal or lower, but it does not represent the real situation of usual blood glucose control. In order to ensure the authenticity of the test results, the medication and meals before the test should be the same as usual. You should also make sure you have a good night’s sleep and don’t have any mental burden! 3, only fasting blood glucose check, less or no check postprandial blood glucose In fact, postprandial blood glucose is also one of the indicators of blood glucose monitoring. In the early stages of diabetes, often manifested as postprandial blood glucose elevation and fasting blood glucose is normal, if only checking the fasting blood glucose, part of the early diabetic patients may be missed. Compared with fasting blood glucose, postprandial blood glucose elevation and diabetic macrovascular complications are more closely related, strict control of postprandial blood glucose, help to prevent and control diabetic macrovascular complications; in the treatment of early diabetic blood glucose is only elevated in the postprandial blood glucose, should be used for postprandial blood glucose short-acting hypoglycemic agent is more appropriate, and for the fasting and postprandial blood glucose is high in the patient, the long and short-acting hypoglycemic agent combined application of the efficacy of a better. Note that for young, first-time diagnosed obese type 2 diabetic patients with a short course of the disease, if they meet the conditions after rigorous preoperative examination and evaluation, they can be metabolically corrected by means of surgery (gastric diversion surgery), so that patients can realize that they do not need to take medication or insulin, and their blood glucose will still be maintained in the normal range, and so that they will not be bothered by testing their blood glucose any more.
