Bali Belly is just one of the names for Traveller’s Diarrhoea (upset stomach), it’s also known as Montezuma’s Revenge or the Rangoon runs. By this point you probably have a good idea of what it is. It is treatable and usually clears up within 24 hours, but it may take a couple of days or even up to a week. Bali Belly symptoms aren’t pleasant:

  • Abdominal bloating, cramps and pain
  • Nausea and/or vomiting
  • Urgency/frequency in going to the toilet
  • Diarrhoea
  • Mild temperature
  • General malaise (weakness or discomfort)


It can occur in a number of places in the world with poor sanitation, hygiene, and water quality. Known causes are Bacteria, Parasites, and Viruses - though there are also cases with unknown causes. There are a number of things you can do to avoid Bali Belly:

  • Avoid the tap water
    • Avoid drinking the water or brushing teeth with it
    • Buy bottled water
    • Boil tap water for at least 5 mins
    • Avoid drinks containing ice
    • Don’t use tap water to wash fruit or vegetables
  • Wash your hands
  • Eat at reputable and clean restaurants
  • Get a Vaccination
  • Avoid certain foods
    • Raw and peeled fruits and vegetables
    • Green leafy vegetables such as spinach and lettuce
    • Raw, rare or undercooked meats of any kind
    • Seafood, particularly raw or inadequately cooked shellfish or fish
    • Sauces and mayonnaises
    • Unpasteurised dairy foods, including milk
    • Food from street vendors
    • Any hot food that has been left long enough to cool
    • Food buffets

So while you might be tempted to eat from some street markets we’d definitely recommend sticking to restaurants and bottled water. It will make your trip much better.
