Finding the right balance between enjoying travel and controlling blood sugar requires that people with diabetes have some key knowledge when traveling and going out. Here are some suggestions for people with diabetes when they travel. 1. It is best to carry a blood glucose meter with you when you travel in order to detect your abnormal blood glucose in time and take appropriate measures. 2. It is generally not recommended to make major changes to the treatment plan during travel to avoid sudden changes in medication that may cause discomfort and inconvenience in seeking medical attention while away from home. If you want to change to oral medication (only for type 2 diabetes) due to inconvenience such as carrying insulin, it is recommended to consult your doctor some time before going out, and if your condition allows, you can change to oral hypoglycemic medication, adjust your medication before going out, monitor your blood sugar, and ensure medication safety and blood sugar control. 3. Patients who apply insulin should pay attention to the preservation of the injections. Opened insulin can generally be stored normally between 4C and 25C and does not affect the application. For patients who travel for a short period of time, it is enough to pay attention to the storage temperature. 4. Familiarize yourself with the characteristics of the drugs you use, make appropriate adjustments according to the diet and activities while traveling, and strengthen monitoring. (1) Take short-acting insulin as an example, it should be injected before three meals. If the morning activity is expected to be heavy (such as hiking, climbing, etc.), the insulin injected before breakfast can be appropriately reduced by a few units. (2) Many patients use premixed insulin (a mixture of short-acting and intermediate-acting insulin), and one injection is given before each of breakfast and dinner. If lunch is expected to be delayed or even if you do not know when you will eat lunch, prepare some dry food when you go out in the morning and eat properly at the usual lunch time to avoid hypoglycemia. (3) For patients taking oral hypoglycemic drugs, they should be familiar with the characteristics of their own hypoglycemic drugs, and they should pay particular attention to insulin stimulants, which can easily lead to large blood sugar fluctuations when diet and exercise are not as usual. 5. In addition to the diet and exercise factor, the work and rest time is different from usual when traveling, and blood glucose may fluctuate, so try to combine work and rest and not to challenge the limits of the body. 6, because of the change of diet and exercise during the trip, also be alert to hypoglycemia, carry with you candy bars, chocolate, etc. Be familiar with the symptoms of hypoglycemia: hunger, panic, cold sweat, shivering, general weakness and even change of consciousness. When you find that it may be hypoglycemia, even if you cannot test your blood sugar at that time, you should immediately eat sugar cubes, sugary drinks, etc., and see if there is any improvement after rest. If hypoglycemia is caused by not eating in time after applying hypoglycemic drugs, after the hypoglycemia is controlled briefly, subsequently eat some main food appropriately. 7. Pay attention to proper hydration. Do not overeat. 8. If there are infections such as cold, diarrhea, fever, or accidental injuries during the trip, they need to be dealt with in time, and in these stressful conditions, they can easily lead to ketoacidosis. In addition, fever, gastrointestinal infections, etc. may cause hypoglycemia under the effect of hypoglycemic drugs due to the influence of feeding and food digestion and absorption, and it is also necessary to pay attention to recognition and self-help. Diabetic patients’ blood glucose control is closely related to daily life (diet, exercise, work and rest, stress, etc.) and medication due to their impaired ability to regulate blood glucose, which can be affected when changes occur in life and body. Self-monitoring of blood glucose is a very important aspect of self-care for diabetic patients. Being able to have a blood glucose meter to keep track of one’s blood glucose is the most practical method for daily and changing blood glucose control. However, at the same time, understanding the effects of diet and exercise on blood glucose and the characteristics of the medications you apply can predictably avoid hyperglycemia or hypoglycemia, stay away from the critical wall and significantly improve the prognosis. Understanding one’s disease, acquiring knowledge of the disease and adjusting one’s lifestyle are very important to ensure the quality of life of many patients with metabolic diseases. Do the part you can do, and your life will be “brighter”.
