Bowel problems and travel

Most people experience disturbance of their bowels when they travel, usually related to a change in diet or water, jet lag, a change of climate, or stress. Bacterial or viral infection, parasites (for instance, a single-celled protozoan called Giardia lamblia) and food poisoning often cause acute diarrhoea.

To avoid infection:

• Don't drink the water if you suspect it is contaminated, and never have ice in your drinks.
• Don't eat food that has been left out.
• Avoid salads.
• Be scrupulous about personal hygiene.
• Use antibacterial handwipes.
