Fasting blood sugar refers to the blood sugar value tested by taking blood before breakfast after fasting overnight (not eating any food, except drinking water for at least 8 to 10 hours). Fasting blood glucose is a commonly used detection indicator for diabetes. It can reflect the function of pancreatic beta cells and generally represents the basal insulin secretion function.
Fasting blood glucose is affected by many factors. If you are not prepared before measuring, it will affect the accuracy of the measurement results. To measure fasting blood sugar, in addition to fasting for 8 to 12 hours, you must also pay attention to the effects of exercise, medication, time schedule, etc.
Try to keep the dinner before the measurement as normal as possible
In order to obtain better fasting blood sugar results, some patients often deliberately reduce their food intake at dinner the day before. This directly results in the fasting blood sugar measured the next day being lower than usual, which is not conducive to the analysis of the condition. In fact, if you want to ensure the most accurate measurement results, you must maintain a normal state, so that you can analyze the impact of daily diet on blood sugar. Of course, eating a large amount of hard-to-digest food for dinner or having a late dinner should also be avoided.
Fasting blood glucose should be measured between 6 a.m. and 8 a.m. in the morning.
To measure fasting blood sugar, you need to fast for 8 to 12 hours. Combined with resting time, the best time period for measuring fasting blood sugar is between 6 a.m. and 8 a.m. in the morning. Some patients often rush to the hospital for examination in the morning without eating or drinking. Their blood sugar is often measured at 8 o'clock or even later. Although the patient is still in the fasting stage at this time, the glucagon hormone in the body is already at 8 o'clock. It will gradually increase later, and the blood sugar measured at this time can no longer reflect the most accurate fasting blood sugar state. Not only that, but in a long-term fasting state, people with diabetes are prone to hypoglycemia events, with disastrous consequences.
Choose the nearest community hospital to complete the test
In addition to the time limit, there are also factors that affect fasting blood sugar when the patient is on the way to the hospital. Some diabetic patients will choose to walk a longer distance to the hospital for treatment, or they may be tired of traveling long distances, so the measured blood sugar will be higher than the actual blood sugar. On the low side; in addition, the unpleasant emotions caused by waiting in line to get a number will also increase blood sugar stress. To prevent these factors from affecting fasting blood glucose measurement, the best way is to complete the test at home or at a nearby community health center, and then go to a large hospital for consultation if necessary.
