Does blood sugar rise after exercise? Most people get it wrong!

Most diabetics know that exercise can play a certain role in lowering blood sugar, but in actual monitoring, it is found that after exercise, blood sugar will increase significantly and will not decrease. Why is this? The following editor will analyze the reasons in detail.

Blood sugar levels do rise after exercise

It is not easy to exercise at an intensity of more than 80%. The heart rate will increase to 90% or even higher, and breathing will become difficult. In order to meet the energy needs of exercise as much as possible, you have to breathe heavily. This level of physical exertion will activate the sympathetic nervous system. At this time, the sympathetic nervous system will become extremely excited, so it can help the human body meet the energy needs of exercise. High-intensity exercise requires high energy consumption, and the sympathetic nervous system can help stimulate endocrine organs, such as the adrenal glands. The adrenal glands will release a large amount of stress hormones, adrenaline and norepinephrine into the blood, which will prompt the liver to produce glucose at a faster frequency. When this frequency exceeds the frequency of glucose absorption by muscle tissue, blood sugar will rise.

Correct exercise is the active way to lower blood sugar

For diabetic patients, blood sugar is highest at noon. Many patients who are treated with insulin only inject insulin in the morning and evening, and the insulin injected in the morning does not work until noon. In addition, many patients eat more at noon, and some patients eat too fast or too hot. If they do not take medicine or exercise at noon, their blood sugar will easily rise. Therefore, it is particularly emphasized that patients should not take a nap immediately after a meal, but should exercise first and then take a nap. Taking medicine is a passive way to lower blood sugar, while exercise is an active way to lower blood sugar. Exercise can not only improve the function of the islets, but also enhance the body's immunity and prevent and treat other diseases.
