Among the five clinical treatment measures for diabetes, diet control and exercise are the most basic and critical measures. Diabetic exercise can improve the patient’s cardiopulmonary function, increase the body’s resistance, facilitate the control of postprandial blood sugar, and prevent the occurrence of osteoporosis at the same time. Diabetic patients are recommended to exercise one hour after meal. One hour after meal, food is basically digested and blood sugar reaches the highest level, at this time, exercise can promote the uptake of glucose by peripheral tissues, facilitate the control of post-prandial blood sugar and prevent the occurrence of hypoglycemia caused by exercise. It is not recommended for diabetic patients to exercise immediately after meals, as immediate exercise can cause an increased burden on the gastrointestinal tract, which is not conducive to the digestion and absorption of food. At the same time, the increased secretion of insulin after meals can cause fluctuations in blood glucose and blood pressure, causing a significant increase in the risk of adverse reactions. Diabetic patients avoid exercise exercise on an empty stomach to avoid hypoglycemia.
