Diabetes is a chronic disease that requires patience and more care. Blood glucose testing is the basis for guiding the adjustment of medication, meals, exercise and other programs. In addition, sugar friends also need to go to the hospital to test glycosylated hemoglobin once every 2 to 3 months in order to accurately grasp the fluctuation of their condition. When self-testing blood glucose at home, you need to avoid 6 misunderstandings and pay attention to details to get accurate results.
First, Don't stop using hypoglycemic drugs without authorization. Many people mistakenly believe that the blood sugar measured when the drug is not used can be used to understand the real situation. Therefore, it is not appropriate to stop the drug one day in advance and then measure the blood sugar. Usually, before and after self-testing fasting blood sugar, you should take hypoglycemic drugs in your usual habits. If in order to assess islet function, you need to consult a doctor, and then stop or resume the use of related drugs as required.
Second,Don't think that the more blood you take, the better. In fact, too much blood will overflow the test area, contaminate the instrument, and cause errors. The correct method is to collect blood from both sides of the ring finger. There are few nerve fibers in this area, which can reduce the pain. Before blood collection, disinfect with alcohol and wait for the alcohol to evaporate before collecting blood to avoid the reaction of alcohol with the test strip and affect the test. When taking blood, the blood volume can cover the test area. Let the blood flow out naturally and do not over-squeeze it to avoid dilution of the tissue fluid, resulting in a low detection value.
Third,to avoid frequently detection. For most patients with stable disease, it can be measured in segments. For example, on the first day, blood glucose was measured 2 hours before breakfast, before dinner, and after breakfast; on the second day, blood glucose was measured 2 hours before and after lunch; on the third day, blood glucose was measured 2 hours before breakfast and after 3 meals; only the diagnosis was confirmed. Need to adjust the treatment plan, occurrence of acute complications, etc., only need to check blood glucose 4 to 7 times a day; in addition, if you change your lifestyle, are pregnant, or adolescent patients, etc., you also need to check blood glucose 4 to 7 times a day .
Fourth,the correct detection of postprandial blood glucose. Postprandial blood glucose, usually refers to the blood glucose 2 hours after a meal, the time is calculated from the first bite of meal, rather than starting to count after the meal. After a meal, blood sugar rises, and the influence of stress needs to be ruled out. If abnormal postprandial blood glucose is found, according to the condition, blood glucose measurement can be arranged 1 hour after meal and 3 hours after meal, which will help to find the delay or advancement of postprandial blood glucose peak.
Fifth,to look at the test results objectively, and do not adjust the medication plan based on the one-time or occasional blood sugar fluctuations. Self-test blood glucose at home, you should record the value in detail, and record the changes in diet and exercise. The test results within a period of time are provided to the doctor, and the drug use plan is adjusted through professional judgment. According to the results of a certain test, increasing or decreasing the dosage of drugs on its own will often bring undesirable consequences.
Sixth, pays attention to the detection of blood sugar before exercise. Because exercise will increase the consumption of glucose and reduce blood sugar, only by measuring the blood sugar level before exercise can we assess whether the amount of exercise is appropriate. At the same time, it should be noted that if you feel unwell during exercise, you also need to test your blood sugar to determine whether hypoglycemia has occurred. By comparing the blood glucose levels under different physical activity states, the amount of exercise can be reasonably arranged. In addition, it should be noted that the exercise time should avoid the time when the blood concentration of insulin or hypoglycemic drugs reaches the peak, and avoid injecting insulin into the exercise limbs, so as to avoid the rapid absorption of insulin and induce hypoglycemia. Finally, there is another technique, which is to measure blood glucose before going to bed when the amount of exercise is large, in order to find delayed changes in blood glucose levels.
