Jot down a few questions to make the most of your conversation.
Can travel-related symptoms need urgent attention?
Yes. After eating contaminated food or drinking unsafe water, some travel-related symptoms can become serious quickly and may need urgent medical assessment. This can happen whether you are abroad or after you return to the UK.
Most stomach bugs pass on their own, but certain warning signs suggest a more severe infection or dehydration. If these appear, do not wait to see if they improve.
What symptoms are concerning?
Severe diarrhoea or vomiting can lead to dehydration, especially in children, older adults and people with long-term health conditions. Warning signs include dizziness, confusion, very dark urine, dry mouth and not passing much urine.
Seek urgent help if you have blood in your stool or vomit, severe tummy pain, a high fever, or diarrhoea that is very frequent or lasting more than a few days. These symptoms may point to a more serious infection.
Emergency symptoms also include fainting, difficulty breathing, chest pain, severe weakness or signs of shock. These need immediate medical attention.
Why food and water can cause serious illness
Contaminated food and water can carry bacteria, viruses or parasites that trigger illnesses such as gastroenteritis, dysentery or typhoid. Some infections cause only mild upset, while others can spread through the body or cause severe fluid loss.
In hot climates, dehydration can develop faster because you lose more fluid through sweating. If you are already unwell, even a short illness can become much more serious.
What to do if symptoms happen after travel
Start by drinking small amounts of water or an oral rehydration solution if you can keep fluids down. Avoid alcohol, and eat lightly if you feel able to eat.
If symptoms are severe or you are worried, contact NHS 111 for advice. If you have danger signs such as confusion, collapse, blood in vomit or stool, or severe dehydration, call 999 or go to A&E.
If you have recently returned from abroad, tell the clinician where you travelled, what you ate or drank, and when symptoms started. This can help identify the cause and the right treatment.
How to reduce the risk
When travelling, drink bottled, boiled or properly treated water where safe tap water is not available. Avoid ice, uncooked foods and unpasteurised dairy if hygiene standards are uncertain.
Wash your hands regularly, especially before eating and after using the toilet. Good hygiene can lower the chance of becoming ill and reduce the risk of passing infection to others.
