Science and what causes elevated blood sugar

　　1. If people are suddenly stimulated by the cold, there will be more adrenalin, which accelerates the breakdown of glycogen, causing a sudden rise in blood sugar.

　　2. Chemical toxicity can also cause sudden increase of blood glucose. For example, chemical toxicity such as streptozotocin can accelerate the destruction of beta cells and cause sudden increase of blood glucose.

　　3. The influence of climate can also cause blood sugar to rise suddenly. Cold stimulation, for example, increases adrenaline production, increases glycogen output from the liver, and decreases glucose uptake by the muscles, which increases blood sugar.

　　4. Some diseases can also cause a sudden rise in blood sugar. Acute pancreatitis is one of them. It tends to raise blood sugar and even lead to diabetes. Therefore, early treatment of acute pancreatitis is very important.

　　5. Dietary reasons cannot be ignored. If people eat too many sweets at one time, the high sugar content of the food will cause a sudden rise in blood sugar.

　　6. It could be a detection error. There are often patients who do not wash their hands before blood glucose measurement, let alone regularly calibrate the blood glucose meter. The deviation of blood glucose value will be caused by the expiration of test paper and the uncorrected blood glucose meter.

　　7. The last factor refers to emotional factors. If a person's mood fluctuates too much, such as sudden sadness and fear, the body can secrete a large amount of norepinephrine and adrenalin and other substances, which can increase the body's energy consumption and increase blood sugar suddenly to some extent.
