Travelin’ Tips with Diabetes


                                      At a garden in Tokyo with friends on a rainy day

Last week I received an email from the American Association of Diabetes Educators offering 8 travel tips, “Have Diabetes, Will Travel.” I thought I would post them.

I also asked AADE why there’s no mention of how to adjust your dose if you take a long-acting insulin like Lantus or Levemir. You’ll find that recommendation at the bottom after we had an email exchange.

Have Diabetes, Will Travel

No Reason You Can’t Enjoy Seeing the World – You Just Need to Plan Ahead 

Just because diabetes is your constant companion doesn’t mean you can’t enjoy traveling, whether traversing America in an RV or flying to the far reaches of the globe. Ensuring you stay healthy and keep your glucose levels on an even keel does require a little bit of organization and planning ahead, though.

The American Association of Diabetes Educators suggests a plan of attack for ensuring your next travel adventure is safe and successful.

1  Over-pack your medications – Gone for a week? Pack two weeks’ worth of your diabetes medications in case of travel delays or misplaced supplies (insulin, syringes, testing strips, extra batteries for your pump, a first-aid kit, glucagon emergency kit, etc.). If you use a pump, ask the company if you can bring a backup in case yours fails. Have a prescription from your doctor for insulin or oral medication in case of an emergency.

2  Protect your supplies – Keep your medications and supplies close at hand and don’t put them in checked luggage or in the trunk, where they can be exposed to harmful extreme temperatures (too hot or too cold). If you’re flying, keep them in the original packaging (so no one questions they’re yours) in a bag separate from your toiletries, as requested by the Transportation Security Administration (TSA), which manages airport security. Don’t worry, the TSA allows you to go over the 3.4 liquid-ounce carry-on limit for diabetes medications and supplies.

3  Identify yourself – Wear your medical bracelet or necklace that notes you have diabetes and take insulin (if you do). Bring a doctor’s note that explains you have diabetes and lists your medications, as well as a prescription in case you need more. Carry a health card that includes your emergency contact and doctor’s name and phone number. Learn how to say “I have diabetes,” “sugar,” and “orange juice, please” in the language of the country you are visiting.

4  Carry snacks and low blood sugar treatment  – Low blood sugar (hypoglycemia) can strike any time and food access during travel is unpredictable, so be sure to bring plenty of snacks such as peanut butter crackers, granola bars and  trail mix as well as glucose tablets or gel.

5  Simplify flying – Tell the TSA folks that you have diabetes (they’re used to accommodating people with health issues).  Visit your trip to learn about current screening policies. If you plan to inject insulin while flying, be forewarned – the pressurized air can make it more challenging to draw up your insulin, if using a vial and syringe, so be extra careful not to inject air into the bottle.

6  Test often – New foods, increased activity and different time zones can throw your glucose levels out of whack, so be sure to test frequently, including before and after meals. If you take insulin, keeping your levels steady can be tricky when changing time zones, so make a plan to adjust your schedule for injecting. Before your trip, see a diabetes educator, who can help you with this challenging process.

7  Favor your feet – Wear comfortable well-fitting shoes and socks at all times – never go barefoot.  Check your feet frequently, especially after a hike or long walk.  Feet and ankles often swell during flights so consider wearing light knee-high compression stockings (20-30 mm Hg) or bring thinner socks to change into if your feet swell.  Wear a shoe that can be loosened if that occurs. Pointing and flexing your ankles during a flight can improve blood flow in your calf muscles and decrease swelling as well as lower the risk of blood clots.

8  Prepare for a health emergency – If you need medical treatment, ask your hotel to recommend a local doctor who treats diabetes. Prior to an overseas trip, get a list of local English-speaking doctors through the International Association for Medica1172l Assistance to Travelers at

The secret to any successful trip is to take plenty of time and plan far in advance of your departure – and that goes double when you have diabetes. For more information about how a diabetes educator can help you plan your next trip, visit

Regarding adjusting your long-acting insulin dose from AADE: “There are adjustments that many people make but we would not recommend any specifics. It’s better to have your HCP guide you. Ask your HCP how to adjust your background insulin to account for the shortened day.

You may also want/need to do extra blood glucose checks during your trip for information as you make insulin adjustments, as well as to account for possible variations in food and physical activity while on your trip.”

I concur. I’d also add, if you’re an old hand and feel confident about adjusting your dose, do a little experimenting. First, use your common sense. Second, keep checking:

If your day is going to be shortened, for instance, by 6 hours, take 1/4 less your normal dose. If your day is going to be lengthened by 6 hours, add an extra quarter. I take that extra quarter before I go to sleep after I’ve arrived somewhere because I take my Lantus at 9 AM. Then I start my usual dose again when 9 AM rolls around wherever I am. And yep, keep checking!

That’s what I do but in all things diabetes what works for me may not be right for you. Mind you, I only take 8 units of Lantus a day and I’m insulin-sensitive rather than insulin-resistant.
