Diabetic patients can promote the recovery of pancreatic islet function through regular aerobic exercise within tolerance according to their physical conditions. Aerobic exercise, such as jogging, brisk walking, aerobics, jumping rope, etc., is recommended for diabetic patients and can help reduce the burden on the pancreatic islets. Exercise is recommended 3 to 4 times a week, and each exercise should be about 30 minutes. However, exercise should be adjusted according to one’s age, weight and heart function, etc. Strenuous exercise such as marathon and sprinting is not recommended, so as not to exceed one’s tolerance level, which can easily cause low blood sugar. Exercise for diabetes is recommended to start about 1 hour after meals, and it is recommended to carry sugary foods such as cookies and candies to prevent hypoglycemia. In addition to exercise, you should also adjust your diet and follow your doctor’s instructions for proper medication.
