New data shows over a third of British travellers face digestive issues, prompting advice on hydration and food safety.
Digestive distress has affected 36 percent of British holidaymakers in the last year, according to new research. The Saga Travel Insurance study surveyed 500 UK travellers to assess the prevalence of "travel tummy," defined as stomach upset or illness experienced while abroad.
The findings highlight that gastrointestinal problems are a common concern for those travelling overseas, often negatively impacting their trips. Half of the respondents (49%) reported experiencing diarrhoea during their holidays. Additionally, nearly one in ten (8%) indicated they battled gut troubles on every single trip.
Individuals with pre-existing conditions, such as irritable bowel syndrome (IBS), may face an elevated risk of complications when travelling, as the journey itself can exacerbate symptoms. When seeking relief abroad, local chemists serve as the first point of contact for 35% of holidaymakers. Almost a third (30%) turn to Google, while one in twelve (8%) consult AI tools to evaluate their symptoms before seeking professional medical advice.
Saga Travel Insurance engaged Dr Nick Burr, a gastroenterologist at LivingCare, to explain the origins of travel-related stomach issues and offer preventive measures. Dr Burr noted that traveller's diarrhoea is frequently caused by bacteria, most commonly E. coli, contracted from contaminated food or water. This risk is particularly present in parts of Asia, Africa, the Middle East, and Central or South America. Symptoms typically include loose stools, cramping, bloating, and nausea, often appearing within the first week of travel.
Tap water quality varies significantly by country. While updated plumbing infrastructure in many nations makes tap water safe for consumption, other regions require caution. Unsafe drinking water can harbour dangerous bacteria, parasites, and chemicals. In such cases, opting for bottled water is advisable. According to the NHS, boiling water remains the most reliable method to purify it and eliminate pathogens. Chemical disinfectants like iodine or chlorine can also be used but may be less effective than thorough boiling followed by cooling in a sterile container. Water filters ranging from 0.2 to 1 micron can remove dirt or parasites prior to chemical disinfection.
Local cuisine was identified as a primary trigger for travel tummy in the survey, with 44% of respondents blaming their holiday stomach troubles on local food. Dr Burr explained that common sources of infection include untreated water, ice cubes, buffets, shellfish, undercooked meat, and food left sitting in the heat. He emphasized that exploring local food is a key aspect of travel and can usually be done safely with common sense. Freshly cooked, piping hot food in a busy restaurant is generally considered safe.
Dehydration poses a significant threat to wellbeing while travelling. Diarrhoea was the most frequently reported symptom among UK travellers, affecting more than a quarter (28%) over the past 12 months. Loose and watery stools lead to fluid and electrolyte loss that exceeds replenishment capabilities. Dr Burr warned that dehydration can be serious, especially in hot climates. Alcohol and caffeine worsen dehydration and have laxative effects, so limiting these substances is recommended while symptoms are severe. Intense exercise may slow recovery, so resting, drinking fluids, and eating simple foods until improvement occurs is advised.
Rehydration solutions effectively prevent dehydration and support recovery. If commercial sachets are unavailable, Dr Burr suggested a homemade alternative: mix six level teaspoons of sugar and half a teaspoon of salt in one litre of clean water.
Beyond bacterial infections, environmental factors contribute to feeling unwell. Dr Burr stated that symptoms are sometimes related to changes in routine rather than infection. Prolonged disruption to sleep patterns, hydration, alcohol intake, stress, and diet can increase digestive system sensitivity, particularly in individuals prone to IBS or functional gut symptoms. The survey revealed that 34% of holidaymakers attributed their travel tummy to travel-related stress, while 27% pointed to long journeys as a contributing factor.
For those experiencing upset stomachs during flights, Dr Burr linked this to cabin pressure changes, dehydration, reduced movement, disrupted sleep, stress, and unfamiliar foods. Staying hydrated, moving around during flights, and eating lighter meals can help reduce discomfort. Michelle Cooper, director of Saga Travel Insurance, added that walking up and down the aisle every two hours on longer flights helps circulation and digestion.
Travellers with underlying health conditions face heightened dangers. Dr Burr noted that people with diabetes, kidney disease, inflammatory bowel disease, or weakened immune systems may become unwell more quickly. Advance preparation is crucial for these individuals, not only for health management but also to ensure adequate travel insurance protection.
Michelle Cooper explained that while many insurers cover pre-existing medical conditions, declaring them when taking out a policy is essential. Becoming unwell abroad with an underlying condition can be more serious, potentially requiring quicker access to medical care or specialised treatment. Securing the right cover ensures support without facing unexpected costs while away.
Most cases of travel tummy are mild, but severe instances necessitate treatment. A visit to a local doctor or a call to an insurer’s 24-hour travel GP service, if available, may be required. Michelle Cooper highlighted that proper insurance coverage allows travellers to get necessary support without worrying about unforeseen expenses during their trip.
