Traveller’s Diarrhoea

Traveller’s diarrhoea is one of the most common illnesses affecting people travelling abroad. It is usually caused by consuming contaminated food or water and is more common in destinations where sanitation or food hygiene standards may be lower than those in the UK.

The condition can be caused by bacteria, viruses or parasites and may affect travellers visiting parts of Asia, Africa, the Middle East, Central and South America.

Although many cases are mild and improve within a few days, traveller’s diarrhoea can disrupt holidays, business trips and long-term travel plans. In some cases, symptoms may become more severe and lead to dehydration or complications, particularly in young children, older adults or people with underlying health conditions.

Reducing risk often involves careful food and water precautions while travelling. In some situations, travellers may also benefit from carrying suitable medication or treatment options before departure.

At Market Harborough Travel Clinic, our team can provide travel health advice on reducing the risk of traveller’s diarrhoea and discuss suitable treatment or prevention options based on your destination and travel plans.
