What Is Bali Belly?
Bali Belly is a local term for traveler’s diarrhea, a common gastrointestinal infection that affects many visitors to Bali. It’s caused by consuming contaminated food or water, leading to symptoms like diarrhea, stomach cramps, nausea, and sometimes fever.
Medically, it falls under gastroenteritis, which is an inflammation of the stomach and intestines.
What Causes Bali Belly?
The main culprits behind Bali Belly are viruses, bacteria, and, in some cases, parasites. According to studies, around 70% of cases are viral, with Rotavirus and Norovirus being the most common. However, bacterial infections caused by Escherichia coli (E. coli), Salmonella, Campylobacter, and Shigella are also frequent triggers. These bacteria can be present in contaminated food and water.
High-Risk Foods That Can Cause Bali Belly:
- Raw or peeled fruits and vegetables – They might be washed in contaminated water.
- Undercooked meat – Bacteria thrive in improperly cooked food.
- Street food from unhygienic vendors – Not all street food is unsafe, but it’s wise to choose vendors with high turnover and visible hygiene practices.
- Unpasteurized dairy products – Certain cheeses and milk can harbor harmful bacteria.
- Seafood – Especially raw or improperly cooked shellfish.

How Long Does Bali Belly Last?

Is Bali Belly Contagious?
Yes, Bali Belly can be contagious, especially if it’s caused by a virus like Norovirus or Rotavirus. It spreads through contaminated food, water, and surfaces. Practicing good hygiene, such as washing your hands frequently, can reduce the risk of transmission.

How to Flush Out Bali Belly
If you do get Bali Belly, don’t panic! Your body will naturally recover, but here’s how to speed up the process:
Stay Hydrated
Diarrhea causes fluid loss, so oral rehydration is key. Drink plenty of water and consider oral rehydration salts (ORS) to replenish lost electrolytes.
Eat the Right Foods
Should you eat with Bali Belly? Yes, but stick to bland foods like:
- Plain rice or toast
- Boiled potatoes
- Bananas (contain pectin, which helps firm stools)
- Applesauce
- Clear broths
Avoid dairy, alcohol, spicy, and oily foods until your stomach settles.
Consider Medication
- Antidiarrheal tablets (like activated charcoal or attapulgite) can help if symptoms are mild.
- Probiotics may aid faster recovery by restoring gut bacteria balance.
- Pain relievers (such as paracetamol) can help with fever and aches.
- Anti-nausea meds may be useful if vomiting is severe.
IV Therapy for Severe Cases
If dehydration persists and you struggle to keep fluids down, IV therapy may be necessary. Many clinics and wellness centers in Bali offer IV rehydration with added nutrients to help you recover quickly.

How to Prevent Bali Belly
Prevention is better than cure. Follow these tips to reduce your risk:
Drink Only Safe Water
Stick to bottled or filtered water. Avoid ice cubes unless you’re sure they’re from purified water.
Choose Food Wisely
Eat at reputable restaurants or busy street food stalls where food is freshly cooked. Avoid pre-cut fruits and salads unless you wash them yourself with bottled water.
Practice Good Hygiene
Wash your hands frequently with soap and water. Use hand sanitizer if soap isn’t available.
Strengthen Your Gut Before Traveling
Taking probiotics before your trip may help build gut resilience against unfamiliar bacteria.
