Millions of Britons With Diabetes Urged to Take Precautions When Travelling Abroad
As the summer holiday season approaches, health experts are issuing an urgent reminder to the UK’s 5.8 million people living with diabetes. With the return of BBC’s Race Across The World highlighting the challenges faced by young travellers such as Fin, an 18-year-old living with Type 1 diabetes, medical professionals are emphasising the increased risks associated with travelling for people managing the condition.
While Type 1 diabetes, commonly diagnosed in childhood, is caused by autoimmune factors, the majority of those affected in the UK—about 90%—live with Type 2 diabetes, which is often the result of lifestyle and genetic factors. Despite these differing origins, both groups need to remain vigilant against common symptoms and complications, particularly when venturing abroad.
Dr Ashwin Sharma, a specialist in diabetes care at the online pharmacy MedExpress, has stressed the importance of advanced preparation and mindful management for diabetic travellers. “Temperatures often surge during holidays and these warmer climates can wreak havoc on blood glucose control,” Dr Sharma explained. “Whether you have Type 1 or Type 2 diabetes, heat can heighten the risk of hypoglycemia, sometimes with little to no warning.”
Another key concern is dehydration. People living with diabetes are especially susceptible to its effects, which manifest as headaches, extreme thirst, dizziness, and fatigue. Dr Sharma advises, “When you’re on holiday, you tend to be more active and exposed to the sun, which only amplifies dehydration risks. It’s vital to keep hydrated and shield yourself from excessive sun exposure whenever possible.”
One practical challenge for people relying on insulin is medication storage. Insulin needs to be kept cool to remain effective. Dr Sharma recommends travelling with a medical-grade cooler bag, or at the very least, a simple insulated bag with ice packs. “If your insulin appears cloudy or has taken on a brownish tint, it could be damaged and should not be used. Anyone with doubts should consult a healthcare provider immediately,” he said.
There are specific steps anyone with diabetes should adopt before and during their travels to minimise avoidable complications. Firstly, close and frequent monitoring of blood glucose levels is highly recommended, as unfamiliar climates and activities can make levels harder to predict. “You should check your sugars more often than you typically do at home, particularly in new environments,” Dr Sharma suggests.
Carrying enough medication is another essential precaution. Apart from keeping insulin cool and never in checked luggage, travellers should pack extra supplies in case of flight delays or cancellations. Alongside insulin, bringing fast-acting carbohydrates—such as glucose tablets or sugary drinks—can be lifesaving in the event of hypoglycaemia.
To further guard against dehydration and its knock-on effect on blood sugar, regular water consumption remains paramount. “Try to stay in the shade during the hottest parts of the day, reapply sunscreen frequently, and drink water even if you don’t feel thirsty,” advises Dr Sharma. These efforts can help stabilise your blood glucose and protect overall health during travel.
Lastly, documentation should never be overlooked. Holidaymakers are encouraged to ensure their Global Health Insurance Card (GHIC) is valid and to arrange comprehensive travel insurance covering diabetes and any related health needs. It is also wise to bring a letter from a healthcare professional outlining the diagnosis and treatment plan, and to inform fellow travellers about the condition in case swift assistance is needed.
The guidance from Dr Sharma underscores a broader message: those with diabetes need not shy away from holidays, but an extra measure of planning and mindfulness is crucial. With thoughtful preparation and a few preventative steps, people living with diabetes can look forward to safe, enjoyable travels this summer and beyond.
