Travel Safety for Older Adults With Diabetes: Managing Your Condition Abroad

Travelling With Diabetes: Why Planning Matters

Diabetes is one of the most common chronic conditions among older adults worldwide. Millions of people aged 60 and over live well with either type 1 or type 2 diabetes, and many travel extensively, enjoying holidays, visiting family, and exploring new destinations throughout their later years. With the right preparation, travelling with diabetes is entirely manageable and should not prevent you from pursuing the travel experiences you enjoy.

However, travel does introduce specific challenges for diabetes management that require advance planning. Changes to eating schedules, time zones, physical activity levels, heat, and the disruption of normal routines can all affect blood sugar control. Access to appropriate food, insulin storage conditions, and medical support may differ significantly from what you are used to at home. Understanding these challenges and preparing for them is the key to safe and enjoyable travel.

Before You Travel: Medical Preparation

Start your travel preparations with your diabetes care team well before departure, ideally six to eight weeks in advance for longer trips. This gives time to arrange prescriptions, documentation, and any necessary adjustments to your management plan.

Ask your doctor or diabetes nurse for a letter confirming your diagnosis, your prescribed medications and devices, and the medical necessity of carrying insulin, syringes, needles, blood glucose monitoring equipment, and any other supplies. This letter should be on headed paper and ideally translated into the language of your destination. It is essential for airport security and may be needed if you require medical attention abroad.

Ensure your travel insurance includes comprehensive coverage for pre-existing conditions, specifically including diabetes. Many standard travel policies exclude or limit coverage for pre-existing conditions. Read the policy carefully and, if necessary, purchase specialist travel insurance that provides full coverage. Confirm that emergency medical evacuation is included in cases where local treatment is inadequate.

Research healthcare facilities at your destination. Know the location of hospitals and clinics near where you will be staying, and find out whether insulin and your specific medications are available locally in case of emergency. The brand names and formulations of insulin can differ between countries, so carrying sufficient supplies from home is generally the safer approach.

Packing Your Diabetes Supplies

Pack significantly more supplies than you think you will need. A general guideline is to bring twice the amount of medication and testing supplies you would use during the trip. This accounts for delays, losses, damaged supplies, and the possibility that your diabetes management may require more frequent monitoring or adjustment while you are away.

Always carry your diabetes supplies in your hand luggage, never in checked baggage. Hold luggage may be exposed to extreme temperatures in aircraft cargo holds, which can damage insulin. It may also be delayed or lost. Your insulin, blood glucose monitor, test strips, lancets, syringes or pen needles, and any other essential supplies should always be with you.

For insulin storage during travel, there are several options. Insulin that has been opened and is in current use can generally be stored at room temperature for up to 28 days, depending on the formulation. Insulin in transit can be kept cool using an insulated travel wallet or a specialist insulin cooling case. Avoid exposing insulin to direct sunlight or extreme heat, as this degrades it rapidly.

Pack a glucagon emergency kit if you have been prescribed one, and ensure at least one travel companion knows how to use it. Carry rapid-acting glucose sources such as glucose tablets, gel, or regular sugary drinks for treating hypoglycaemia. Have these accessible at all times, not buried in a bag.

Managing Insulin and Devices at Airport Security

Insulin, syringes, needles, and blood glucose monitors are permitted in hand luggage on flights, but you will need to be prepared for security screening.

Inform security staff that you have diabetes and are carrying medical supplies before you go through the scanner. Your doctor's letter and a list of your medications helps security staff understand what you are carrying. In most countries, insulin pens and syringes are allowed through security with appropriate documentation. However, rules can vary between airlines and countries, so check in advance with your airline and the airport authority at your destination.

Insulin pumps and continuous glucose monitors (CGMs) can generally be worn through metal detectors and body scanners. If you are concerned about the effect of airport scanners on your pump or CGM, ask for a manual pat-down instead. This is your right at most international airports.

Allow extra time at airports to manage the security process without rushing. Stress can affect blood sugar levels, so staying calm is both practically and medically beneficial.

Managing Blood Sugar Across Time Zones

Travelling across multiple time zones can significantly disrupt your medication schedule, particularly if you take insulin or other medications at fixed times of day. Discuss with your diabetes team before travel how to adjust your medication timing when crossing time zones.

A general principle is that travelling east (shortening your day) means fewer doses may be needed, while travelling west (lengthening your day) may require additional doses. However, individual circumstances, the type of insulin you use, and whether you use a pump or injections all affect the specific guidance. Do not make significant adjustments to your insulin regimen without medical advice.

Keep your watch or phone set to home time during the adjustment period if your team has given you time-based instructions for medication. Test your blood sugar more frequently than usual during travel days and in the first few days after arrival, as the combination of disrupted routine, different food, and time zone change often causes blood sugar to behave less predictably.

Food and Blood Sugar Management While Travelling

One of the greatest challenges of travel for people with diabetes is maintaining a consistent diet in an unfamiliar food environment. Restaurant meals, buffets, local street food, and unusual eating times all make carbohydrate counting and portion control more difficult.

Research the typical cuisine of your destination before you go. Identify which dishes are likely to be high in refined carbohydrates and which are more suitable. In countries where rice, bread, or pasta form the basis of most meals, you may need to adjust your approach. Learning a few key phrases in the local language about your dietary needs, such as requesting low-sugar options or asking about ingredients, can be very helpful.

Carry suitable snacks at all times to manage unexpected delays in meals. Protein-based snacks and complex carbohydrates help maintain more stable blood sugar than sugary alternatives. However, also keep rapid glucose sources readily available for treating hypoglycaemia.

Be cautious about alcohol intake, particularly in social holiday settings. Alcohol can both raise and lower blood sugar and can mask the symptoms of hypoglycaemia. If you choose to drink, do so in moderation and with food, and test your blood sugar more frequently.

Heat, Physical Activity, and Blood Sugar

Hot climates have specific implications for diabetes management. Heat can accelerate insulin absorption, potentially causing blood sugar to drop more quickly than expected. Heat also affects the storage life of insulin and the accuracy of some blood glucose monitoring equipment.

If you are travelling to a hot destination, monitor your blood sugar more frequently, particularly after physical activity or extended time outdoors. Keep insulin and monitoring equipment out of direct sunlight and in a cool location. Do not leave them in a hot car or on a beach towel in the sun.

Physical activity levels typically change during holidays. Walking tours, beach activities, swimming, and sightseeing often involve significantly more exercise than your normal daily routine. Increased physical activity generally lowers blood sugar, so you may need to adjust carbohydrate intake or insulin doses accordingly. Discuss anticipated activity levels with your diabetes team before travel.

Stay well hydrated in hot climates. Dehydration can concentrate blood glucose levels and increase the risk of hyperglycaemia. Drink water regularly throughout the day without waiting until you feel thirsty.

Recognising and Treating Hypoglycaemia Abroad

Hypoglycaemia, or a hypo, is a blood sugar level that drops below safe levels and can cause symptoms including shakiness, sweating, confusion, weakness, and in severe cases, loss of consciousness. Managing a hypo abroad requires having the right supplies immediately to hand and ensuring your travel companions know what to do.

Treat mild to moderate hypoglycaemia with 15 to 20 grams of fast-acting glucose: four to five glucose tablets, 150 to 200ml of regular (not diet) fizzy drink, or glucose gel. Wait 15 minutes and test again. If still low, repeat the treatment. Once blood sugar has recovered, eat a snack containing complex carbohydrates to stabilise it.

If you are travelling with a companion, ensure they know the signs of a hypo and how to respond. If you have a glucagon kit, show them how to use it before you travel. If you are travelling alone, wear a medical ID that clearly identifies you as having diabetes. This is critically important if you were to become confused or unresponsive and unable to communicate with emergency responders who may not speak your language.

Seeking Medical Help Abroad

If you need medical attention for a diabetes-related issue while abroad, your travel insurance provider is your first point of contact. Their 24-hour emergency line can direct you to appropriate medical facilities and, where necessary, coordinate your care or evacuation.

Carry a copy of your most recent test results, your HbA1c level, a list of your current medications with generic (not just brand) names and doses, and your doctor's contact details. This information is invaluable for any doctor treating you who is unfamiliar with your history.

In many countries, pharmacies can provide basic diabetes supplies in emergency situations. However, insulin formulations and concentrations differ internationally, so be cautious about substituting unfamiliar products without medical guidance. If you are unsure about a locally purchased product, contact your travel insurance provider or a diabetes helpline for advice.

Enjoying Your Travels

Living well with diabetes includes travelling the world if that is what you want to do. Millions of older adults with diabetes make international trips every year without incident because they prepare thoroughly and manage their condition with care.

Inform your travel companions about your diabetes and what they should do in an emergency. Keep your supplies organised and accessible. Test your blood sugar more frequently during travel days and when routines change. Rest when you need to. And give yourself credit for the extra effort that travelling with diabetes requires, because the rewards of seeing the world are absolutely worth it.
