Blood sugar testing is a commonplace problem, but many people still don't know why to do so. The aim of self-test is to understand the level of blood sugar control and the influencing factors of blood sugar changes in diabetic patients, and help patients balance their diet, exercise and dosage in daily life.
In normal blood glucose measurement, fasting and post meal time points which can represent the changes of blood glucose should be selected. However, due to the influence of working time, most of them only involve before and after breakfast in the hospital. Blood sugar changes are affected by three meals. Hypoglycemic drugs are often taken with each meal. If you want to know whether the dosage is appropriate, you should monitor the blood sugar before and after three meals, including before going to bed at night, or even 2:00-3:00 a.m. (the lowest point of blood sugar in the whole day). In addition, in case of any condition that may affect the change of blood glucose, it is also necessary to measure blood glucose. If there are hypoglycemia symptoms (such as hunger, panic, sweating, etc.), it is necessary to measure blood glucose in time to guide further drug dosage adjustment. Usually, diet has the greatest influence on blood sugar, such as the best relative fixed staple food. Before fasting and postprandial blood glucose was reduced to 6.0mmol/l, the main method was to measure the postprandial blood glucose. When the fasting blood glucose basically reaches the standard, we should pay attention to monitoring the blood glucose for 2 hours after meal, and we can also choose the time of blood collection according to our own situation. To find out the trend of blood sugar change in time is helpful to adjust the antidiabetic drugs.
After choosing the time, we need to know the basic situation of our blood sugar, which needs to be measured every day, and we can choose by leaps and bounds. For example, on the first day, the blood glucose of the morning and evening before meal and 2 hours after breakfast is measured, on the second day, the blood glucose of the morning and evening before meal and 2 hours after lunch is measured, and on the third day, the blood glucose of the morning and evening before meal and 2 hours after meal is measured; after the blood glucose control is stable, the monitoring frequency is reduced, and the blood glucose of the week is monitored for 2-3 days; finally, after the blood glucose control is up to the standard, the blood glucose of the week is measured for 2-5 times without randomly changing the diet ratio, which is optional Choose a different time. But after changing our lifestyle, we should monitor blood sugar in time. When we go out, changes in our eating habits, different sleeping conditions, and increased mental tension are all factors that affect blood sugar. Therefore, we need to adjust the dosage of the drug to control the fluctuation of blood sugar, so as to minimize the fluctuation, which is the most important principle to protect diabetic patients.
Precautions for measurement: Generally speaking, finger blood should be taken for fast blood glucose meter to measure blood glucose, and the two sides of finger abdomen should be selected for the site to avoid direct blood collection from finger abdomen or finger tip, reduce the damage of these highly sensitive and common sites, prevent secondary infection and reduce pain. With the development of blood glucose meter, the blood demand for each time is also reduced a lot. The blood demand for the least one time measurement is only 0.3 μ L. when patients choose the blood glucose meter, they should pay attention to read the instructions clearly. To disinfect the skin of the blood collection part, it is better to use 75% alcohol and dip it with a sterile cotton ball or swab. It needs an area about 1-2cm in diameter. After disinfection, wait for a few seconds, wait for the skin to dry naturally and then take blood. It is not suitable to use disinfectant with color, because it is easy to interfere with blood glucose measurement. When there is no disinfectant, you can use cleaning solution or soap to clean the blood collection part, and wash it with clear water and dry it naturally.
