First, choose the right form of exercise. For example, glucose patients with retinopathy (a diabetic eye disease) should avoid exercises such as lifting dumbbells; diabetic neuropathy patients should not do foot stretches or other exercises that affect the extremities. In addition, heart disease, autonomic dysfunction and kidney disease and other complications of diabetes can also affect the choice of exercise intensity. In addition, sugar lovers must keep in mind eight notes before exercise: 1. Self-measurement of blood sugar before and after exercise. The American Diabetes Association recommends avoiding exercise if pre-meal blood sugar (fasting blood sugar) is higher than 13.89 mmol/L and ketosis is present. Blood glucose over 16, 67 mmol/L and no ketosis, sugar lovers should be highly alert. Before exercise, if blood glucose is lower than 5.56 mmol/l, you can eat a snack and retest blood glucose after 15 minutes, blood glucose is normal before starting exercise. 2, write exercise log. The content includes: the effect of different exercises (exercise intensity and exercise volume) and environment (temperature, etc.) on blood glucose, and the eating situation before and after exercise. This information can help to grasp the pattern of blood sugar changes, and also help to adjust the treatment plan. 3, prepare some “emergency” candy. Exercise may lead to lower blood sugar, or even hypoglycemia. It is best to prepare some food that can provide energy quickly, such as glucose jelly or glucose tablets, sweets, candy or juice. 4. Do not inject insulin before exercise. Muscles metabolize insulin more quickly during exercise, and insulin before exercise may lead to the risk of hypoglycemia. 5, often drink water. It is especially important for sugar lovers to drink the right amount of water before, during and after the three phases of exercise. Timely hydration can prevent dehydration of the body and prevent blood sugar fluctuations and heat stroke. 6, carry a medical card. It is best to carry a medical card or wristband that shows your identity and condition when you exercise. Once fainting occurs, others can better give first aid help. 7, fully warmed up and relaxed. The American Diabetes Association recommends that before exercise, sugar users should perform a 5-10 minute aerobic warm-up, for example, low-intensity walking or cycling, plus 5-10 minutes of small stretching exercises. At the end of the exercise, you should relax for 5-10 minutes to bring your heart rate back to the pre-exercise level. 8. Dress appropriately and comfortably. Sports shoes and socks must fit, sportswear must be breathable and appropriate. This can help prevent foot problems and avoid heat stroke.
