How to travel with diabetes: A complete guide

Travelling with diabetes can feel like a lot to manage. You’ve got your usual routine to think about – checking blood sugar levels, taking medication – and then you add airports, different climates, new foods, and time zones into the mix.

It’s completely normal to feel a bit unsure before you go.

The good news is that with the right preparation, travelling with diabetes can be just as enjoyable as any other trip. Travel Insurance for diabetes is designed to support people just like you, who don’t want their condition to hold them back from seeing the world.

This guide covers the practical things that actually make a difference. Discover what to pack, how to prepare, and how to handle common situations while you’re away.

Can diabetics travel?

Yes – absolutely. Having diabetes doesn’t mean you have to miss out on travelling. If you’re living with Type 1, Type 2, or gestational diabetes, you can travel safely as long as you plan ahead.

Everyone manages their diabetes differently, so what works for one person might not work for another. But the key things are the same:

• Make sure your condition is stable before you go
• Take everything you need – and a bit extra
• Have the right Travel Insurance in place

Once you’ve covered those basics, travelling becomes much less stressful and a lot more enjoyable.

Can diabetics travel by plane?

You can – and plenty of people do every day. The main thing is keeping everything you need close to you. 

Always pack your medication and diabetes supplies in your hand luggage, not your suitcase. If your checked bag gets delayed or lost, you don’t want to be without essential medication. It also helps to keep things organised:

• Keep medication in its original packaging
• Use a clear bag for security checks
• Bring a doctor’s letter explaining what you’re carrying

If you use insulin, this is especially important. Temperatures in the aircraft hold can fluctuate, which isn’t ideal for storing it.

The diabetes travel checklist

Packing for a trip with diabetes is really about being prepared for the “what ifs”. Here’s a simple checklist to work from:

• Medication (bring more than you think you’ll need) – Delays, cancellations, or changes in plans can happen, so it’s always best to pack extra. Aim for at least a few days’ additional supply, just in case.

• Insulin, needles or pens – Make sure you have everything you need to take your medication as usual. Double-check quantities before you travel, especially for longer trips.

• Blood glucose monitor or CGM (plus spares) – Bring your usual device, along with a backup if possible. If you use a Continuous Glucose Monitor, consider packing a spare sensor.

• Test strips and lancets – You may need to check your blood sugar more often while travelling, so bring more than your normal daily amount.

• Hypo treatments you’re familiar with – Whether it’s glucose tablets, sweets, or drinks, bring options you know work well for you. You might not find the same products abroad.

• A doctor’s letter – This explains your condition and medication, which can help at airport security and is useful if you need medical support while you’re away.

• A sharps disposal container – A small travel-sized sharps bin allows you to safely dispose of needles, especially if you’re moving between locations.

• A cooling bag for insulin – Insulin needs to be kept at a stable temperature, particularly in warmer climates. A cooling pouch helps protect it when you’re out and about.

• Emergency contact details – Include important information like your condition, medication, GP details, and a contact person in case of an emergency.

It might feel like a lot to think about. But once it’s packed, you’ll have peace of mind knowing you’re ready for anything.

What are the risks of travelling with diabetes?

Travelling can affect your routine in ways you might not expect, which can impact your blood sugar levels. That doesn’t mean you shouldn’t travel – just that it helps to know what to look out for.

While these risks are important to be aware of, they’re all manageable with a bit of preparation and planning. Here are some of the most common challenges diabetics face while travelling abroad:

1. Time zone changes

If you’re travelling long-haul, your usual routine will shift. You may be eating at different times or sleeping at unusual hours. It can take a few days to adjust – so it’s a good idea to check your levels more often while your body settles into the new time zone.

2. Heat and temperature changes

Warmer climates can affect how your body responds to insulin. In some cases, insulin may absorb more quickly, which can increase the risk of hypos. Heat can also:

• Affect the accuracy of glucose monitors
• Increase your risk of dehydration
• Make it harder to keep insulin at the right temperature

Taking regular breaks in the shade and staying hydrated can make a big difference.

3. Changes to your routine

Holidays often mean different meal times, new foods, and more activity than usual. You might find yourself:

• Eating later than normal
• Trying unfamiliar foods
• Walking more or being more active

All of these can affect your blood sugar, so it’s worth keeping an eye on your levels and adjusting where needed.

4. Storing your medication

Keeping insulin at the right temperature is important, especially in hot destinations.

Most hotels will have a fridge, but it’s worth checking before you travel. If not, staff are often happy to help store medication safely.

When you’re out and about, a cooling pouch can help keep insulin at a safe temperature.

5. Access to medical care

If you’re travelling somewhere remote, access to medical care may be more limited. It’s worth thinking about:

• How far you are from the nearest hospital
• Whether pharmacies are easy to access
• What you would do in an emergency

This is where having the right Travel Insurance becomes especially important, so you know support is there if you need it.

Should diabetes affect where and how you travel?

Not necessarily – but it can help to think a little more carefully about your plans. Having diabetes doesn’t mean you need to limit where you go. It just means being a bit more aware of how different environments and situations might affect you and planning around that.

The climate

Temperature can play a bigger role than you might expect.

Hot weather can cause insulin to be absorbed more quickly and increase your risk of dehydration. On the other hand, very cold conditions can affect how well your devices work and how your body responds to insulin.

That doesn’t mean you should avoid certain destinations. You may need to take a few extra precautions depending on where you’re going.

Access to medical care

Not all destinations offer the same level of healthcare. If you’re travelling somewhere more remote, it’s worth thinking about:

• How easy it is to reach a hospital or clinic
• Whether medication and supplies are available locally
• What you would do if you needed urgent care

You don’t need to overthink it, but having a rough plan can give you peace of mind.

Your accommodation

Where you stay can make a real difference to how easy it is to manage your diabetes while you’re away.

It’s helpful to check:

• Whether there’s a fridge for storing insulin
• If there’s air conditioning or a cool space in hot climates
• How easy it is to access food and drinks when you need them

Small details like this can make your day-to-day routine much easier.

The type of trip you’re taking

Different holidays come with different routines. For example:

• A relaxing beach holiday may mean less structure around meals
• A city break could involve lots of walking and activity
• A cruise or organised trip may give you a more predictable schedule

Thinking about how your trip might affect your routine can help you prepare in advance.

Travel Insurance

Even with the best planning, things don’t always go exactly as expected.

That’s why having specialist Travel Insurance for diabetes is so important. It means you can access medical care if you need it and won’t be left worrying about unexpected costs while you’re away.

How to prepare for your trip

A little preparation goes a long way when you’re travelling with diabetes. Once you’ve got everything organised, it becomes much easier to relax and enjoy your time away.

What supplies should you take?

Start with the essentials, as these are the things you rely on every day:

• Insulin and medication – Make sure you have enough for your whole trip, plus extra in case of delays
• Needles or insulin pens – Double-check quantities before you go
• Hypo treatments – Bring options you know work for you, as alternatives may not be available abroad
• Glucose monitor and test strips – You may need to test more often than usual while travelling
• Ketone test strips – Particularly important if you feel unwell or your blood sugar runs high
• A travel-sized sharps bin – For safe and hygienic disposal of needles

Remember, it’s always better to overpack than risk running out.

What should go in your hand luggage?

Your hand luggage should contain anything you might need during the journey, or anything you can’t afford to lose. Make sure you keep:

• All medication
• A cooling bag for insulin
• Your doctor’s letter
• Snacks to help manage blood sugar
• Spare batteries or chargers for your devices

Keeping everything close by means you’re prepared for delays, long journeys, or any unexpected changes.

How should you pack your medication?

Keeping your medication safe and at the right temperature is key.

Here are a few simple tips:

• Use a cooling pouch to keep insulin at a stable temperature
• Keep medication in its original packaging
• Store essentials somewhere easy to reach
• Use protective cases for insulin pens to avoid damage

It’s all about making sure your medication stays effective and accessible when you need it.

Do you need a doctor’s letter?

It’s not always required, but it’s strongly recommended. Your letter should include:

• The type of diabetes you have
• The medication you’re carrying
• Contact details for your GP or diabetes team

It can help avoid delays at airport security and makes it easier for medical professionals to support you if needed.

How to prepare before you travel

Before you set off, it’s worth taking a few extra steps:

• Arrange Travel Insurance that covers your diabetes
• Pack extra medication and supplies
• Learn a few useful phrases if you’re travelling abroad – like “I have diabetes”
• Save important contacts in your phone
• Check local emergency numbers at your destination

These small steps can make a big difference if something doesn’t go to plan.

What about long-haul travel?

If you’re travelling across time zones, your routine may need adjusting. You might need to change when you take insulin or eat meals, depending on your destination.

If you’re unsure, it’s always best to speak to your GP or diabetes team before you travel. They can give you advice tailored to your situation.

Travelling with diabetes

Once you’re on your trip, it’s really about staying aware of how your body feels and making small adjustments as needed.

Things might not always go exactly to plan. Knowing how to handle common situations can help you stay in control and enjoy your time away.

What if you get ill while you’re away?

Getting ill can affect your blood sugar levels, often causing them to rise as your body fights infection.

If you’re unwell:

• Try to stay hydrated, especially if you have a fever, vomiting, or diarrhoea
• Check your blood sugar more frequently than usual
• Monitor your ketone levels if your blood sugar is high

If you’re struggling to keep fluids down or your symptoms get worse, it’s important to seek medical help as soon as possible.

Diabetes, sun exposure and heat

Spending time in the sun is part of many holidays, but heat can have a bigger impact than you might expect.

Hot weather can:

• Make insulin absorb more quickly
• Increase the risk of dehydration
• Affect your blood sugar levels

To help manage this:

• Drink plenty of water throughout the day
• Take regular breaks in the shade
• Check your blood sugar more often than usual

If you’re out for long periods, it’s also worth protecting your devices and medication from direct heat.

10 Tips for travelling with diabetes

A few simple habits can make managing your diabetes much easier while you’re away:

1. Monitor your blood sugar more often – New environments, different foods, and changes in routine can all affect your levels. Checking a bit more frequently helps you stay in control and spot any changes early.

2. Always carry snacks – Blood sugar levels can drop unexpectedly, especially if meals are delayed, or you’re more active than usual. Keeping snacks or glucose tablets with you means you’re always prepared.

3. Store insulin properly – Temperature matters. Keep insulin cool, especially in hot climates, using a cooling pouch when you’re out and about. Avoid leaving it in direct sunlight or in a hot car.

4. Adjust your routine for time zones – Travelling long-haul can disrupt your usual schedule. You may need to change when you eat or take medication, so plan ahead and check your levels more regularly while you adjust.

5. Wear or carry a medical ID – In an emergency, this can quickly let others know you have diabetes and help them respond appropriately.

6. Let your travel companions know how to help – Whether it’s recognising the signs of a hypo or knowing where you keep your medication, having someone aware of your condition can be really reassuring.

7. Be cautious with tap water – In some destinations, drinking tap water can increase your risk of illness, which can affect your blood sugar. If you’re unsure, stick to bottled water.

8. Check your feet daily – If you’re doing more walking than usual, it’s important to look out for any cuts, blisters, or irritation – especially if you have reduced sensation due to neuropathy.

9. Keep track of meals and insulin – With different foods and meal times, it can help to stay mindful of what you’re eating and when you’re taking insulin, so you can adjust if needed.

10. Know the local emergency number – It’s a small detail that’s easy to overlook, but knowing who to call in an emergency can save valuable time.

Travelling with diabetes – you’ve got this

Travelling with diabetes might take a bit more planning, but it shouldn’t stop you from enjoying your time away.

Once you’ve got your essentials packed, your routine in mind, and the right support in place, it becomes much easier to relax into your trip. Most of the time, it’s about small adjustments rather than big changes. 

Stay aware of your surroundings and listen to your body. And if something unexpected does happen, having the right diabetes Travel Insurance means you’re not dealing with it alone.

Make the most of your holiday, exploring new places, and enjoying the experience.
