Two peaks of blood sugar a day

- Normal blood glucose concentration increases 3 times a day with three meals, blood glucose will continue to rise for 2 hours after each meal, 6 hours a day within 24 hours of blood glucose rise, the remaining 18 hours are at fasting levels. This regular change is due to the central nervous system, sensory nerves and endocrine gland regulation. After a meal, insulin secretion will generally increase, on the other hand, the decomposition of liver glycogen and the conversion of protein and fat into glucose glycogen, promote the conversion of blood sugar into liver glycogen, into muscle, fat and other tissues, so through these two aspects, it will prevent the source of blood sugar and accelerate the use of blood sugar, blood sugar concentration will not be excessive after a meal. 2 hours after a meal, insulin secretion will return to the level before meals, blood sugar will drop. In short, normal people's blood sugar is three meals a day, there are three increases, that is, three peaks, not two peaks, the peak will last for 2 hours, with the secretion of insulin and return to the level before meals, that is, after the central nervous system, sympathetic nerve and endocrine gland regulation in the body, so that blood sugar is relatively stable within a relatively narrow range, to ensure that important organs of the human body, such as the brain get sufficient sugar supply, will not let show other problems.
