If you rush for 1 hour in the morning to measure your fasting blood glucose, your blood glucose may decrease, increase or remain unchanged, and there is a big difference between individuals, so it should depend on the situation. 1. Lower blood glucose: If the patient walks or rides a bicycle to the hospital for up to 1 hour, the patient will consume a lot of glucose on the road, which will make the blood glucose drop, and some patients may even experience hypoglycemia. If symptoms of hypoglycemia occur, sugar should be replenished in time. 2. Elevated blood glucose: If the patient exercises strenuously on the way to the hospital, resulting in elevated glucagon, but measures blood glucose without resting when measuring blood glucose, there may be elevated blood glucose. 3. Unchanged blood glucose: If the patient goes to the hospital to measure blood glucose by riding in a car, etc., and has less physical exertion on the way, there may be no change in blood glucose. Consult your doctor for more information on the specific precautions for checking fasting blood glucose.
