Diabetes and Travel: How to plan, pack, and manage supplies

Whether you're traveling by air, sea, rail, or road, having diabetes means planning ahead to stay safe and avoid unexpected challenges

Whether you’re a new or seasoned traveller, planning a trip can be both fun and stressful at the same time, especially when you’re living with diabetes. In addition to packing the right clothes and shoes, you also need to bring your diabetes therapy supplies and manage your blood glucose on the go.

While this may sound a bit overwhelming, you can manage what you need to do with some thoughtful planning and preparation. Here are some basic tips for traveling with diabetes to help you be well-prepared for your travels. 

Double up on diabetes management supplies

When traveling with insulin and other diabetes supplies, it’s important to determine how much you’ll need to bring on your trip. 

As a general guideline, pack double the amount of insulin and other diabetes management supplies you need for the time you’ll be away. That means one week of travel equals two weeks of diabetes supplies. 

Take double the testing supplies, medications, low blood sugar treatments, pump accessories, and other medical items you think you'll need. And if you use a pump, pack a backup.

If you're flying, keep your supplies in your carry-on baggage so you don't have to worry about it being delayed or not arriving at all.

For road trips, use an insulated bag to prevent your diabetes supplies from potentially overheating in your car. Heat can have a negative effect on the stability of insulin or the function of devices such as your pump.¹ Please also consult the manufacturer's instructions for your insulin and other devices.

Embrace your new time zone

Depending on how far you go, the direction of travel, and how long you'll be visiting, your healthcare provider may recommend adjusting your therapy and checking your blood glucose more frequently. So before you leave, speak to a member of your healthcare team about how to manage your blood sugar as you cross time zones , especially if you use insulin.

Jet lag not only influences your sleep, it can also affect how your body uses insulin, how you eat, and how well you can interpret your blood sugar levels, so try to pay close attention to your numbers.²

Bring your own snacks

The availability of food can be inconsistent when you’re traveling. Airlines may not serve full meals or snacks without a fee, and you may experience delays. Roadside dining may not offer options that fit your diabetes diet , whereas cruise lines often have an overabundance of foods and drinks. 

That’s why packing a few (or a dozen, depending on how long and far you’re traveling) snacks, nuts, or fruit bars with predictable carb counts can come in handy. 

Make sure you have a fast-acting carbohydrate source to treat low blood sugar .

Pay attention to your blood sugar 

Traveling can often disrupt your regular routine. Walking an extra 20,000 steps a day, eating meals late at night, or changing your sleep schedule can impact your blood glucose levels in unpredictable ways. 

Before leaving for your trip, discuss your travel itinerary with your healthcare provider, and discuss how changes in time zones, activity levels, or meals might affect your blood sugar.

Be open about your diabetes diagnosis 

Tell airport security, travel companions, hosts, and anyone else who needs to know that you have diabetes. Let people know what low blood sugar levels look like for you. 

A note from your doctor can also be helpful to explain the extra syringes, insulin pens, infusion sets, medications, and containers of used sharp objects in your bag.

While there are many considerations, traveling with diabetes is still worth the extra planning.

Global travel restrictions, varying guidelines across countries, and airline regulations can complicate the travel experience for individuals with diabetes. From security screening rules to supply allowances, each aspect requires careful attention.

Keep these tips in mind to help avoid any surprises at the airport or in the air.

Navigating security rules can be difficult. If you're traveling by air with diabetes, you might face some challenges due to varying international travel regulations. Different countries and airlines have different guidelines for travelers with diabetes, so it's best to do some research before you fly. 

Check out the diabetes management options available at your destination, including insulin availability and local healthcare systems, to ensure you're prepared.

Regardless of your destination, it's crucial to check with your insulin pump and CGM manufacturer regarding airport security equipment compatibility. Inform security about these devices and request that they not be removed during screening.

By being informed and prepared, you can navigate airport security with ease.

How to manage diabetes in the air

Here are a few tips to help manage your diabetes during your flight:⁴

• Bring plenty of snacks for the airport and on the plane. You never know when a flight may be delayed. Additionally, many flights only offer in-flight beverage service. You never know when you'll need your own snacks or meals.
• Stay hydrated with non-alcoholic, caffeine-free drinks, and consider juices or soft drinks to help with hypoglycemia symptoms.
• If there is an on-board meal, wait until you see the food cart coming down the aisle before you take any pre-meal insulin.
• Keep your watch set to your home time zone until you arrive so you can stick to your regular medication schedule or the one you and your doctor agreed to before the trip.
• Let the flight attendants know you have diabetes, especially if you're traveling alone.
• Some airlines may have policies that require you to turn off Bluetooth-enabled devices, such as CGMs, during take-off and landing. Double-check with the airline beforehand to ensure you follow their specific guidelines.
• Check your blood sugar regularly to ensure that excitement, time zones, or changes in activity and eating habits aren't affecting your levels.

There’s a good chance you already keep hard candy or fast-acting glucose in your car in case you have low blood sugar. If not, this is a great opportunity to find a safe spot for these items in your vehicle. 

To prepare for longer car rides or road trips, here’s a checklist of items for your diabetes road kit that can be kept in your on-the-go bag.

Diabetes road kit:

• A nutritious, fairly substantial snack: Individually wrapped granola bars, dried fruit and nuts, or crackers with cheese can quickly provide much-needed carbohydrates.
• Water: Drink plenty of water or other non-alcoholic, caffeine-free beverages before, during, and after your trip to stay hydrated.
• A double batch of testing supplies and medications: If you're going to be away from home, bring along double the amount of everything you need. Alcohol swabs or moist towelettes have many uses but are especially handy for cleaning up a fingertip.
• Sun, rain, and bug repellent: Diabetes can cause slower wound healing.⁵ If you're going to be outdoors, be sure to apply sunscreen and bug spray to avoid any potential complications.
• A well-charged phone and medical ID: You never know when an emergency will occur, so get in the habit of keeping your ID on you and your phone battery charged.

Now that you have done your research on how to travel with diabetes and packed your snacks, medications, and supplies, you can relax and enjoy yourself. By being well-prepared, prioritizing your needs, and communicating openly about your diabetes, you can balance taking care of your health and enjoying your trip to the fullest. 

While these are helpful tips, it’s good to keep in mind that they may not cover everything you need to know. Before you go on a trip, it's always a good idea to check with your healthcare team to make sure you have everything you need. Safe travels!
