Travelling, holidays and festivals are some of life’s greatest joys — but for people living with diabetes, they can also bring a mix of excitement and concern. Changes in routine, irregular meal times, different foods, higher activity levels and disrupted sleep can all affect blood-sugar levels. Whether you’re taking a weekend break within the UK, flying abroad for a holiday, or enjoying a festive celebration with family, planning ahead can help you stay safe while still enjoying every moment.
At Diabetes Pharmacy, we support thousands of people across the UK in managing diabetes confidently in day-to-day life — and that includes moments of travel and celebration. This guide offers practical, easy-to-follow advice to keep your glucose levels steady while you explore, relax or celebrate.
Why Travel and Festivals Affect Blood Sugar
Any major change in your routine can influence your blood glucose. Travel often involves long periods of sitting, unpredictable meal times, new foods, temperature changes, and sometimes time-zone shifts. During festivals or family celebrations, there may be sweet treats, richer meals, irregular eating patterns and higher excitement levels — all of which can cause glucose fluctuations.
Understanding how these factors affect your body helps you prepare rather than worry. With the right steps in place, people with diabetes can travel safely and enjoy celebrations just like anyone else.
Pack Smart: Your Diabetes Travel Essentials
Preparation is the foundation of smooth diabetes management. Before you leave home, make sure you pack more supplies than you think you might need. Unexpected travel delays or changes in plans are common, so having extra equipment provides peace of mind.
Carry all your diabetes supplies — including medication, glucose tablets, pens, test strips, and CGM sensors — in your hand luggage when flying. Temperature-sensitive medication such as insulin should never go in checked luggage. For modern glucose monitoring, many people prefer using tools such as the FreeStyle Libre 2 Plus or FreeStyle Libre 3 CGM Sensor to track glucose changes easily while away from home.
It’s also a good idea to carry a small diabetes travel letter from your GP, especially when flying or carrying injectable items. Planning ahead helps avoid issues at security checks and ensures you have the right medication at the right time.
Stick to Balanced Meals — Even When Options Are Limited
Food is one of the biggest challenges during travel and celebrations. Airport meals, hotel buffets, festival foods and family feasts often contain more carbohydrates, sugar or fat than your normal meals.
The key is not to restrict yourself excessively but to stay intentional. Try to choose meals that include protein, fibre and slow-release carbohydrates. If you’re indulging in something sweet — like a festival dessert or holiday treat — pair it with protein such as yogurt, nuts, cheese or a balanced main meal to help reduce glucose spikes.
If you’re travelling abroad, research local foods in advance to understand which dishes contain hidden sugars or starches. Keeping snacks like nuts, fruit, or wholegrain crackers with you helps you avoid relying solely on unpredictable foods while travelling.
Keep Meal Timing as Consistent as Possible
Travel can disrupt your usual eating schedule. Long flights, time-zone changes or late-night celebrations may push meals later than usual. If you use insulin or medication that increases insulin production, maintaining safe timing is crucial to avoid lows.
Try to keep meals within a similar pattern to what your body is used to. If meals are delayed, small balanced snacks can help you stay steady until your main meal. Carrying a few quick-acting glucose options is essential — especially during travel where access to food is unpredictable.
At festivals or family events, eating small portions more frequently can work better than waiting for one large meal.
Monitor More Frequently During Travel or Festive Days
When your routine changes, your blood sugar can behave unpredictably. Monitoring more often gives you valuable insight into how your body is responding. If you use a glucometer, bring extra test strips and ensure you have backup batteries. If you use a CGM device such as the FreeStyle Libre 2 Plus or FreeStyle Libre 3 CGM Sensor, make sure you apply a fresh sensor before travelling or bring spares.
Checking regularly helps you adjust meals, insulin or activity safely. It also provides peace of mind so you can enjoy your holiday or celebration fully.
Stay Active — But Be Aware of Glucose Changes
Travel often means extra physical activity — walking long distances, exploring new places, dancing at festivals or carrying luggage. Increased movement generally lowers blood sugar, but the effect varies from person to person.
If you’re more active than usual, you may notice your glucose dropping faster than expected. Monitoring helps you stay aware of these changes. Keep a snack on hand when sightseeing or attending events, especially if you’re on insulin or medications that can cause hypoglycaemia.
During holidays, light activity after meals — such as a 10-minute walk — can help stabilise glucose and improve digestion. These small habits make a big difference.
Stay Hydrated — Especially in Warm Weather
Dehydration can raise blood-sugar levels and make you feel fatigued. When travelling or celebrating outdoors, especially in warmer regions or crowded festival spaces, your fluid needs increase. Drink water regularly throughout the day and avoid relying solely on sugary drinks, energy drinks or alcohol.
If you choose alcohol during celebrations, pair it with food and stay aware of how it may affect your blood sugar hours later. Some people experience delayed drops after drinking.
Plan for the Unexpected
Even with careful planning, unexpected situations can happen — delayed meals, missing luggage, travel sickness, or running out of supplies. Preparing a simple emergency plan keeps you confident and safe. Carrying spare medication, extra glucose, and essential supplies ensures you’re ready for changes.
For international travel, knowing the local equivalent of your medication and locating nearby pharmacies is helpful. When travelling within the UK, keeping a backup prescription or contacting your healthcare provider ahead of time ensures a smoother experience.
