Doctor warns 5.8 million people about holidaying with common illness

Doctor Ashwin Sharma says there are additional risks and steps you need to take to stay safe

BBC’s Race Across The World has returned, and includes eighteen-year-old Fin shining a light on his diabetes journey whilst travelling. It’s estimated that 5.8 million people in the UK are living with diabetes.

While Fin lives with Type 1 – an autoimmune condition often diagnosed in childhood – around 90% of cases in the UK are Type 2, which is closely linked to risk factors like obesity and lifestyle. Despite their different causes, both types share many of the same symptoms.

Doctor Ashwin Sharma from the online pharmacy MedExpress, who specialises in diabetes management, said people need to be aware f the risks when they are going on holiday, adding: “Increased temperatures on holiday can pose additional challenges for those living with Type 1 or Type 2 Diabetes, as heat can affect blood glucose regulation and increase the risk of hypoglycemia.

“Those with diabetes are also more susceptible to dehydration, especially when on holiday, which can present symptoms such as fatigue, dizziness, increased thirst and headaches.

“It is essential for those travelling with insulin to store their medication in a cool, temperature-controlled location to maintain its effectiveness. This could be as simple as a cooler bag. Insulin that has been exposed to excess heat may become compromised, so if your medication appears cloudy or discoloured (brown), then you mustn’t use it and consult a healthcare professional as soon as possible.”

Five Doctor-approved tips on managing diabetes when on holiday

Monitor blood sugar levels – “Blood glucose levels can fluctuate more easily in hotter climates, so it is essential to monitor your levels more closely. Proactive management can help reduce any risk of hypo, supporting your overall stability while abroad.”

Keep insulin cool when travelling – “Insulin is a temperature sensitive medication, so maintaining its integrity is crucial when you travel. Always make sure to carry your medication in your hand luggage, preferably in a medical grade cooler pack to avoid damage or heat exposure.

“When travelling, remember to pack more medication than normal to protect yourself in the event of flight delays or cancellations, and do not use insulin if it appears cloudy or discoloured.”

Managing Hypoglycemia – “Be sure to carry sugary drinks, snacks or glucose tablets at all times when travelling to allow for prompt regulation of blood glucose levels. Due to warmer climates and increased physical activity commonly associated with holidays, levels tend to fluctuate more.”

Avoiding dehydration – “Those with diabetes are at a higher risk of dehydration, which can impact blood sugar levels. Staying well-hydrated with plenty of water, avoiding long spells in the sun and applying sunscreen as often as possible are all measures that can protect your overall health and help stabilise your glucose levels.”

Medical documents and insurance – “Before travel, ensure you have an up-to-date Global Health Insurance Card (GHIC), and comprehensive travel insurance which covers diabetes and any other medical conditions you may have.

I would also recommend carrying a letter from your healthcare provider detailing your condition, treatment plan and any emergency needs. As well as this, ensure anyone you are travelling with is aware of your condition so they can support if needed.”
