What Are Blood Sugar Spikes?

Measuring blood sugar is measuring the sugar in human blood. In most cases, glucose is measured. Most of the energy required for cell activities in the body comes from glucose, so blood glucose must be maintained at a certain level to maintain the needs of various organs and tissues in the body.

Blood glucose

Measuring blood sugar is measuring the sugar in human blood. In most cases, glucose is measured. Most of the energy required for cell activities in the body comes from glucose, so blood glucose must be maintained at a certain level to maintain the needs of various organs and tissues in the body.

Generally, the blood or ear blood measured in the market refers to capillary blood glucose, which is slightly higher than the venous blood glucose. But be aware that when cold, edema, and

Usually fasting blood glucose (

If you think you have a recent infection, fever, vomiting, diarrhea, trauma, etc. and you see a blood test "by the way," you find that your blood sugar is high, then this "hyperglycemia" cannot be used as a basis for diabetes. You should test your blood glucose again when you are well,

If you have other chronic diseases, if you continue to use the drug (including contraceptives), you must inform your doctor and discuss whether you need to stop the drug, whether the condition allows the drug to be stopped, how long to stop the drug, because many drugs can affect the reliability of blood glucose results. Sex.

If you have a history of severe gastrointestinal disorders (oral inflammatory diarrhea, malabsorption, major gastrectomy, dumping syndrome, etc.), you must tell your doctor to consider using an IV Glucose + IV Glucose Test (Medical (Called IVGTT).

3 days before blood drawing, the daily intake of carbohydrates should be greater than 250g (it can be reduced to more than 150 ~ 200g for those who are frail and thin), and keep the mental and emotional well. If you have troubles, anxiety, insomnia, etc., you should postpone the inspection. .

The dinner one night before the blood draw should be a daily ordinary diet. If you eat a lot of big fish and meat, the test results the next day are not reliable.

Fasting (including drinks and snacks, moderate drinking of fresh water when thirsty), no smoking and drinking, and at least 8 to 10 hours of fasting on the next day of blood drawing, but it should not exceed 16 hours. .

Based on the above, the blood glucose measured in the fasting state is called "fasting blood glucose (FPG)". Usually come to the hospital to rest for about 15 minutes before taking blood, it is best to take blood before 8 o'clock in the morning, too late to have a certain impact on the reliability of the results-in real life, the 8 o'clock clinic only starts! Therefore, for patients, it is best to pay the fees for the first day after opening the test sheet, and go to the hospital the next morning to take a blood test directly. ^[1]

1. Don't stop medicine for checking fasting blood glucose without authorization. The test results obtained in this way can not only accurately reflect the condition, but also cause blood glucose and make the condition worse.

2. For patients who have injected premixed insulin before breakfast and dinner, if they are delayed due to blood tests at the hospital in the morning, they can temporarily change the injection after blood sampling and before meals.

Misunderstanding 1: Asymptomatic, do not measure blood sugar, do not go to hospital

Many diabetic patients go to the hospital to take a blood glucose test and find that the blood glucose control is not good. When a doctor asks if there is regular blood glucose monitoring, many "sugar friends" say that blood glucose will only be measured when they go to the hospital. If they don't have any symptoms, they won't take it. Sometimes they only take it twice a year. Experts believe that if a patient occasionally goes to the hospital to measure blood sugar and then prescribe medicine, it will cause a certain degree of misleading to the doctor. The doctor is likely to increase the dose according to a blood glucose index, and the blood glucose index does not fully reflect the patient's usual blood glucose status. .

Misunderstanding 2: Optical measurement of "finger blood glucose"

"Dieyou" can not measure "finger blood glucose" lightly while measuring blood glucose, but also "glycated hemoglobin", so as to reflect the average blood glucose level in the past three months, which is helpful for doctors to judge the condition. "Finger blood glucose" and "Glycated hemoglobin" are like two grades of a class. "Finger blood glucose" reflects the results of one exam, and "Glycated hemoglobin" reflects the average grade of the class in three months.

Misunderstanding 3: Only measure blood sugar after fasting or after breakfast

If the patient goes to the hospital the next day for testing and prescribing, some "sugar friends" will deliberately eat less on the day of the test and strengthen exercise. The next day, they will only measure the blood glucose after the meal. The glycemic index is OK, but it is not normal. . Experts believe that if blood glucose is measured once a month, it is not measured. Some patients have high blood sugar. They should have insulin before breakfast, but if the blood glucose is to be measured the next day, they will not be insulin. The patient said that he would like to know the blood sugar when he did not take injections or medicine. The diagnosis is bad. ^[2]

1. Pain is light on the ventral side. Nancy, 54, has just been diagnosed with type 2 diabetes. She said, "During the blood test, my middle finger was stabbed and felt a little painful." The physician suggested that she try other areas that did not feel pain . As a result, she found that the pain on the ventral side of the finger close to the nail was significantly reduced, almost no feeling, and more comfortable.

2. Avoid sticking your fingertips. Dr. Yuparinger said that the nerve endings at the fingertips are rich and sensitive. Therefore, sticking to the side of the finger, or pressing near the blood collection point when there is little blood, has analgesic effect.

3 Disinfect your fingers with alcohol. Alcohol can cause skin dryness, and there will be significant pain when tying fingers to take blood. It is recommended to wash hands with warm water and stick.

4 Choose the right blood glucose meter. If there is always a problem of insufficient blood collection, it is best to change to a better blood glucose meter. Some blood glucose meters can use blood taken from parts of the body other than your fingers to measure blood sugar.

5. Blood collection equipment should not be reused. Understand the correct use of blood collection equipment, you should use a new blood collection needle each time. Lancing needles are used more often and will become dull, which will cause deep pain in the stinging fingers.

6. Do not squeeze blood from your fingertips. If you don't bleed immediately after fingering, or the amount of bleeding is not enough, it is best to hang your hand naturally and wait 5 seconds. If necessary, squeeze upwards from the palm. Never squeeze from your fingertips.

7. Change your fingers frequently to get blood. It is best to take turns to take turns or to keep a memorable method. Fingers take turns to collect blood. Try not to take blood on fingers that are already painful. Wait until the pain has improved before changing the finger to take blood. ^[3]

In 2018, a research team at Nagoya University in Japan developed a contact lens type continuous blood glucose monitor that does not require external wireless power supply. The device collects blood glucose data every minute and uses the sugar contained in tear fluid to generate electricity and store electricity on its own. The research team is currently working on improving the accuracy of monitoring, and the product has not yet entered the production stage. ^[4-6]
