Exercise is an important part of the comprehensive treatment process of the “five horsemen” of diabetes, and appropriate and moderate exercise is beneficial to the control of the disease. We advocate aerobic exercise, such as walking, jogging, swimming, climbing stairs, cycling, playing badminton or table tennis, dancing, doing exercises, boxing, etc. However, for patients with serious complications of diabetes, such as diabetic proliferative retinopathy, diabetic nephropathy, coronary heart disease, ischemic stroke, diabetic foot disease, cardiac insufficiency, light exercise is a better choice, such as walking, tai chi, etc. Travel is a relatively physically demanding exercise, so diabetic patients must do it according to their age and physical strength. Diabetic patients can travel only when they have stable blood sugar control and no obvious or serious acute or chronic complications. Patients and their families can also go to the professional service center of the hospital for consultation. The Department of Endocrinology of Shanghai Fifth People’s Hospital has a diabetes health education base, and rehabilitation instructors will provide diabetic patients with all kinds of diabetes science knowledge and rehabilitation guidance. Diabetic patients should be well prepared before traveling. 1. Type 1 diabetic patients should carry insulin and blood glucose meter properly; 2. Type 1 diabetic patients should anticipate the amount of medication and carry enough. During the journey, in addition to preventing physical overdraft, extra attention should be paid to issues such as dietary hygiene, blood glucose monitoring and reasonable storage of insulin, and avoid inappropriate travel activities, such as driving by oneself, taking transportation for a long time, traveling in a hot environment, traveling for too long a time, too large a range, and travel requiring long distances. Patients should immediately terminate their travel and go to the hospital to prevent accidents once they have symptoms such as labored breathing, chest tightness and breath-holding, dizziness and headache, and pale face.
