A third of holidaymakers fail to disclose all their medical conditions or health issues because they fear insurance premiums would be unaffordable, a new poll shows.

The study by Boots UK found that travellers under 35 are mostly pre-occupied with allergies, while older travellers are concerned with heart disease and high blood pressure.

However, two-thirds of those surveyed said they were more likely to enjoy their holiday with the peace of mind that they had purchased specialist medical travel insurance cover.

With more people travelling into the later stages of life, the evolution of today’s traveller is predicated by the on-going health issues they may have to contend with.

According to the survey, the number one medical condition travellers expect to become more prevalent over time is high/raised blood pressure, closely followed by heart disease and diabetes.

Cancer and mental health issues make up the top five of medical concerns.

Boots UK senior healthcare commercial manager, Steve Nugent, said: “We want to help our customers make sure they have the right travel insurance cover to ensure they are fully protected when they’re on holiday and we’d never recommend taking a risk and traveling without the right cover.

“We understand that whether you’re a teenager embarking on your first holiday adventure or a 75 year old looking to relax in sunnier climes, the health issues you face are very different.

“Our research shows that allergies and sports injuries are major concerns to the younger traveller, while high blood pressure and diabetes are affecting the older traveller.”
