Preventing problems while travelling if you have diabetes
Travel can make it hard to keep your blood sugar within your target range because of changes in time zones, meal schedules, and types of foods available. Check your blood sugar level more often during your time away from home.
Whenever you need to see a health professional away from home, let him or her know you have diabetes. In addition, always wear medical identification. In an emergency, medical identification lets people know that you have diabetes so they can care for you appropriately if you are unable to speak.
General travel tips
When you are travelling:
- Use a travel agent who knows the needs of a person with diabetes. The agent can arrange for special meals or other special travel needs.
- Take extra diabetes pills (if you have type 2 diabetes), insulin and injection supplies, blood sugar meter batteries, test strips, and lancets. You may not find your regular supplies wherever you travel.
- Double your normal amount of needed supplies for short trips. For long trips, have enough extra supplies to last for 2 weeks more than the length of your trip.
- To keep your blood sugar at your usual level, try to eat and take your medicine as close to your regular schedule as you can.
Car travel
When you are travelling by car:
- Have snacks and drinks with you. Keep sugar-free drinks and drinks with sugar in an ice cooler.
- If needed, store your insulin in the cooler so that it will stay at a more constant temperature. Don't let the insulin touch the ice.
- Keep your blood sugar meter at room temperature. Don't leave it in a hot or cold car or in the sun.
- Walk a few minutes every 2 hours to improve the blood flow in your legs.
Plane travel
When you are flying:
- Check with your doctor, if needed, about changing your insulin dose and timing if you will travel across three or more time zones.
- Pack your diabetes supplies in your carry-on bag. Luggage can get lost and supplies damaged by the temperature extremes in the baggage area. You will need medical identification or a doctor's prescription for your needles and syringes to be allowed through airport security.
- Put your insulin bottle (vial), if needed, into a small, wide-mouth, cool, empty thermos if you are not sure that temperatures will stay in a range that is safe for your insulin.
- Put in half the air you usually add to the insulin vial, if needed, to adjust for altitude air pressure changes if you draw up your insulin while flying.
- Get up and walk every hour or so. This will help blood flow in your legs and will make sure that your insulin works properly.
International travel
When you are travelling to other countries:
- Find out which immunizations are needed for your trip. Get immunized at least 3 to 4 weeks before you travel. These injections can increase your blood sugar for a short time.
- Visit your doctor if you take insulin and are travelling overseas. Ask for a letter stating that you have diabetes and need to carry syringes and other supplies with you at all times. Also, ask for an extra prescription for your insulin. Take both with you on your trip to help you pass through customs with your syringes, needles, and other injection supplies. In some countries, insulin is available in U-40 concentrations only. If you have to use this concentration, you will need to use syringes that are designed to dispense this concentration.
- Pack a small disposable container with you to hold your used lancets and needles (wide-mouth plastic soda pop or water bottles work well).
- Pack a supply of non-prescription medications (that will not affect blood sugar levels) to treat minor illnesses such as a cold.
- Pack a language/translation book or other type of aid that will help you express your diabetes needs to others if you are travelling to a country where English is not the main language.
