Traveller's Diarrhoea

Most cases of traveller's diarrhoea are self-limiting, resolving within 3-5 days without specific treatment beyond rehydration. Bacterial causes typically produce symptoms lasting 3-7 days if untreated, though appropriate antibiotic therapy can reduce this to 1-3 days. Viral diarrhoea generally resolves within 2-3 days. Parasitic infections tend to cause more prolonged symptoms, sometimes lasting weeks if untreated. If symptoms don't improve after 5-7 days, worsen after initial improvement, or include bloody stools or high fever, medical evaluation is recommended.

While most cases resolve without complications, certain symptoms warrant prompt medical attention. Seek help if you experience: persistent high fever (above 39°C/102°F); blood or pus in stools; severe abdominal pain that is constant rather than cramping; signs of significant dehydration (decreased urination, extreme thirst, dizziness, or confusion); symptoms persisting beyond 5-7 days despite self-treatment; or inability to keep down liquids due to vomiting for more than 24 hours. Children, pregnant women, older adults, and those with underlying health conditions should have a lower threshold for seeking care, as they're more vulnerable to complications. When travelling in remote areas, consider communicating with healthcare providers via telemedicine if available. Upon returning home, consult your GP if symptoms persist or recur, especially if you've travelled to areas where parasitic infections are common, as these may require specific testing and treatment not routinely performed for acute diarrhoea.

The traditional advice to follow a restrictive BRAT diet (bananas, rice, applesauce, toast) during recovery has largely been replaced by more flexible guidance. Once your appetite returns, focus on easily digestible, bland foods while gradually returning to your normal diet. Good initial choices include crackers, plain rice, baked potatoes, cooked carrots, baked chicken or fish without spices, and yogurt containing live cultures (which may help restore beneficial gut bacteria). Small, frequent meals are often better tolerated than large ones. Stay well-hydrated with safe water, clear broths, and oral rehydration solutions.

Temporarily avoid foods that may aggravate the digestive system, including spicy or fatty foods, dairy products (except yogurt with live cultures), caffeine, alcohol, and large amounts of raw fruits or vegetables. There's no need to fast or restrict food entirely unless vomiting is present. Listen to your body—if certain foods cause discomfort, avoid them temporarily. Most people can gradually return to their normal diet within a few days as symptoms resolve. If dietary tolerance doesn't improve within a week, consult a healthcare provider.
