Traveling with Diabetes: A Complete Guide to Safe and Stress-Free Travel

Flying with Diabetes: What to Know Before You Go

First, visit your airline or other operator's website to review their specific guidelines for passengers with diabetes, as you may need to complete certain forms before your trip.

Packing and Labeling Diabetes Supplies for Air Travel

It’s important to carry your insulin and other diabetes medication with you at all times in your carry-on luggage. This includes your glucose meter, blood glucose meter, test strips, lancet, and emergency glucose tablets.

Make sure all medications are properly labeled with your name and manufacturer details. Always follow your doctor’s instructions as outlined on your travel certificate. Proper labeling helps prevent confusion during airport security checks.

If you use an insulin pump, inform security staff before screening. Present your medical documentation and clearly state that it’s for managing diabetes.

Airport Security Screening with Insulin and Medical Devices

To avoid unnecessary discussions or misunderstandings about diabetes devices being deemed 'dangerous' at airport security, it’s helpful to inform the security staff in advance that you are carrying medical supplies. Additionally, it's a good idea to arrive earlier than the recommended time, as security checks involving insulin, syringes, and continuous glucose monitoring devices may take a few extra minutes.¹

During air travel, you are permitted to carry liquids like fruit-juice, or gels for treating hypoglycemia or low blood glucose, even in quantities exceeding 100 mL. Ensure these items are easily accessible and inform security during screening. Syringes and needles are also allowed in your carry-on luggage, provided you are carrying the injectable medication (e.g., insulin) with you.²

Any medications including injectables such as insulin should be accompanied with a medical clearance letter provided by your doctor.

Adjusting insulin for time zone changes

• When traveling with diabetes across time zones, consider talking to your doctor or diabetes educator before adjusting your medication schedule or dosage.
• Depending on whether you're traveling east or west, the length of your travel day may vary, which can affect your insulin dosage.
• If you're crossing time zones, it's important to review your meal and insulin schedule with your doctor or diabetes educator.²

Monitoring your blood sugar levels more frequently during travel can help prevent hyperglycemic or hypoglycemic episodes. This is especially important if you are at risk of diabetic ketoacidosis.

Sleeping and Eating Meals During your Flight

If you plan to sleep during your flight, ensure you don't miss mealtimes or medication times. To help with this, set an alarm on your phone or another device, or ask the airline crew to assist you in staying on schedule.

Before your flight, make sure to check with your airline and inform them if you require special meals tailored for people with diabetes. It’s also a good idea to carry an extra snack or two, along with insulin, in case you're unable to accurately count carbs in an unfamiliar meal, which could lead to hypoglycemia or hyperglycemia. When traveling across time zones, keep in mind that meals will be served at different times than usual, which may disrupt your regular eating schedule. Try to adjust your medication accordingly, and find the best way to manage these changes ahead of time.

Arriving at your destination and time change

 Jet lag can affect your awareness of symptoms of low blood sugar levels or high blood glucose levels. Upon arrival, immediately test your levels using your blood glucose test supplies.

The time difference may mask symptoms such as fatigue, thirst, or shakiness — common indicators of diabetes symptoms related to unstable glucose levels.

Increase your frequency of self monitoring for the first 24–48 hours until your levels are back under control.

Hiking and Outdoor Travel with Diabetes

Hiking alone is not advised. Inform someone of your route and expected return time.

Higher elevations and increased physical activity can affect your glucose level and insulin needs. Hiking requires more energy, so pack sufficient food and fluids to maintain proper metabolism and avoid lows.

Always carry:

• Your blood glucose meter
• Extra test strips
• Emergency carbohydrates
• A first aid kit

Proper preparation helps you manage your diabetes safely in remote environments.
