During the Spring Festival, many diabetic patients who are in a foreign country travel thousands of miles to their homes in order to reunite with their families. Some diabetic patients may choose to take the train, bus or drive a long distance home, in this case, patients will stay in this closed, small and crowded space for a long time, for blood sugar control is extremely unfavorable. 1, diabetic patients should be fully prepared before starting the journey with enough therapeutic drugs, including insulin, insulin pen, injection needles, alcohol, cotton swabs, oral hypoglycemic drugs and other necessary drugs, such as nitroglycerin, antibiotics, anti-cold drugs, anti-diarrhea drugs, etc., for emergency use. Meanwhile, during the Spring Festival, there may be long queues for tickets and boarding. Therefore, patients should wear a pair of comfortable shoes and do a good job of foot care, so as not to damage the foot skin leading to infection and the formation of diabetic foot. 2, the car is not at home, patients in the process of riding the car, diet and water are limited, the car or roadside food provided by many are not suitable for diabetic patients to eat. Therefore, it is best for patients to prepare their own food suitable for them before starting the journey, eat on time, and also ensure that they consume enough water, because diabetic patients are prone to dehydration, and if they are dehydrated, it may lead to palpitations, rising blood sugar and other symptoms. It is important to note that patients using medication or insulin therapy need to carry snacks such as candy, chocolates and small cookies with them to prevent the occurrence of hypoglycemia. 3. If the drive is long, patients may become sedentary. Therefore, patients with diabetes combined with lower limb vascular disease or peripheral neuropathy should pay attention: if you sit on the seat for a long time, you should stand up and move more often. It is recommended to get up and walk every half hour, which can improve the circulation of the lower limb blood vessels and also move the muscles and bones, which is also a way to increase the amount of exercise.
