Traveling with insulin: How to be well prepared for your holiday

A diabetes diagnosis no longer means that you have to stay home. With the right preparation and measures, you can discover even the most remote corners of the world. Wherever you go, transporting your insulin properly and keeping it at the right temperature is crucial. In this blog – based on the insights from “Traveling with Diabetes” by Uwe Diegel – you will discover what to look out for when you go on holiday with insulin.

1. Preparation: the basis for a carefree trip

Talk to your healthcare provider and insurer

• Consult with your doctor : Discuss your travel plans, especially for time differences and different climates. Ask what to do in case of illness or emergency and check whether glucagon (for severe hypoglycemia) is an option for you.
• Talk to your pharmacist : Ask for a list of all your medications (including generic names and dosages). This is useful for customs checks and in case you need new insulin abroad.
• Check your insurance : Some insurance policies do not cover pre-existing conditions such as diabetes. Make sure you are properly insured and take copies of your insurance papers with you.

Documents in order

• Travel certificate : Ask your doctor to write a statement (in English) stating that you have diabetes, need insulin and that you need to transport it cool (2-8°C). This can make customs checks run smoothly.
• Diabetes ID : Carry a diabetes card or card in your wallet. This way, healthcare providers will know what is going on if you unexpectedly become unwell.
• Vaccinations : Get vaccinated at least four weeks before departure so that you have overcome any side effects before your trip.

2. Keeping insulin at the right temperature

Why temperature is so important

• Too warm : Above 25°C, insulin loses its effect after some time and becomes less effective.
• Too Cold or Frozen : Insulin that freezes develops crystals that make injection unpleasant and unsafe.
• Ideal between 2 and 8°C : At this temperature, insulin remains stable for up to months.

Cooling solutions for on the go

• Cooler bags (EasyBag, iCool, LifeinaBag)
  • EasyBag : Activate the gel crystals by briefly immersing the bag in water, after which you can store insulin for up to several days at around 16-25°C.
  • iCool and LifeinaBag : Use reusable cooling elements that keep your insulin between 2 and 8°C for 24-36 hours (depending on the model).
• Mini fridges (LifeinaBox)
  • LifeinaBox : The world's smallest smart fridge with built-in battery (up to 6 hours without power). Via an app you can continuously monitor the temperature. Perfect for longer trips or irregular conditions.

Helpful tips

• In a hotel room, use a (mini)fridge that stays powered: in many hotels, the power goes out when you remove the room door card. Therefore, leave an old card or pass in the slot so that the fridge keeps cooling.
• Want to (re)freeze cool packs? Ask the hotel bar or kitchen to put them in their freezer; it is often more powerful than a minibar.

3. Transport of insulin during the journey

On the plane

• Take insulin as hand luggage : This will prevent you from running out if your suitcases get lost. Also, it can sometimes get too cold in the cargo hold.
• Customs & security : Inform in advance that you have diabetes and are carrying medical supplies. Provide clear labels and a doctor's note. Also report if you use an insulin pump (if necessary, ask for manual control in a private room).
• Time zones : If you travel across more than two time zones, adjust your insulin schedule (in consultation with your doctor). Sometimes you need to administer less or more insulin if the day gets shorter or longer.
• Extra time : Get to the airport a little earlier so you don't get stressed about an extra security check of your medical bag.

By car, bus or train

• Regular testing : Check your blood sugar before departure and every few hours while en route.
• Monitor your hypos : Keep sugary snacks (glucose tablets, fruit juice) within reach. Do not drive if you feel a hypo coming on.
• Keep moving : Stop regularly to stretch your legs and move around a bit. This will help your blood circulation and keep you alert.

On the boat

• Buffets : Cruises are known for their lavish meals. Try to keep it regular and not snack too much.
• Inform the crew : Let them know you have diabetes so they can help you if you have any problems.

Camping or hiking

• Don't go alone : ​​Especially in remote areas, it is important that someone knows where you are if something goes wrong.
• Avoid large variations in blood sugars : Intense exercise can quickly lower your blood sugar. Consult your doctor beforehand whether you need to adjust your insulin dose.
• Wear suitable shoes : Foot care is essential. Bring first aid kits to treat wounds immediately.

4. Points of attention on site

Check your blood sugar regularly

Due to different daily rhythms, different food and more or less exercise your values ​​can go in all directions. Therefore take enough test strips and spare batteries for your glucose meter.

Dealing with illness or emergencies

• Continue using insulin even if you eat little.
• Drink plenty of (preferably sugar-free) fluids.
• If vomiting or diarrhea occurs repeatedly, seek immediate medical attention.

Alcohol and diabetes

• Alcohol increases the risk of hypos, especially during holidays full of parties and fun.
• Eat carbohydrates with your drink, check your blood sugar regularly and make sure someone around you knows what to do in case of a hypo.
• Please note: Glucagon does not work well if you have alcohol in your blood.
