Bali belly is the informal name many travellers use for an upset stomach or traveller’s diarrhoea in Bali. It can happen even on a carefully planned trip, but a few sensible habits can lower your risk and make it easier to recover if it does happen.
This guide covers bali belly prevention, what to pack for Bali belly, how to respond if symptoms start, and when to get medical help. It is practical travel advice, not a substitute for professional medical care.

What is Bali belly?
Bali belly usually refers to stomach upset during or after a trip to Bali. Travellers may experience diarrhoea, cramps, nausea, vomiting, feverishness or general weakness. Symptoms can vary from mild and short-lived to more disruptive.
The cause is not always obvious. In many cases, traveller’s diarrhoea is linked to exposure to unfamiliar bacteria, viruses or parasites through food, water, hands or surfaces. Heat, alcohol, jet lag, rich food and dehydration can also make you feel worse.
If you are travelling with children, are pregnant, have a chronic medical condition or are immunocompromised, it is wise to discuss travel health planning with a medical professional before your trip.
Bali belly prevention: practical habits that help
Be careful with drinking water
In Bali, many travellers avoid drinking untreated tap water. Use sealed bottled water or properly filtered water where available, and check before using tap water for brushing teeth if you are unsure. If a bottle seal looks broken or questionable, choose another one.
Ice can be a grey area. Many established venues use commercially produced ice, but if a place looks uncertain or hygiene standards seem poor, it is reasonable to skip ice.
Choose food with care
Bali has excellent food, from warungs to fine dining, and eating locally is part of the experience. The aim is not to avoid everything, but to make sensible choices.
- Choose food that is cooked fresh and served hot.
- Be more cautious with raw salads, unpeeled fruit and food sitting out at room temperature.
- Pick busy places with steady turnover, as food is often prepared more frequently.
- If seafood, meat or dairy smells or tastes wrong, stop eating it.
- Ease into richer, spicier food if your stomach is sensitive after a long flight.
Keep hand hygiene simple but consistent
Wash hands before eating and after using the bathroom. Carry hand sanitiser for taxis, markets, beaches and temples where handwashing facilities may be limited. Avoid touching your face after handling cash, scooters, menus or shared surfaces until you have cleaned your hands.
Take care with swimming and activities
Try not to swallow pool, river or sea water. After waterfall visits, rafting, snorkelling or beach days, wash hands before eating. If you have cuts or open skin, keep them clean and covered where practical.
Do not overdo alcohol, heat and dehydration
Long-haul travel from Europe, tropical heat, late nights and alcohol can all affect your stomach. Drink safe water regularly, use sun protection and take rest seriously during the first few days. A tired and dehydrated traveller often feels stomach symptoms more intensely.
What to pack for Bali belly
A small health kit can make a difficult day much easier. Bring familiar products from home where possible, especially if you know what suits your body. Check medicine rules before travelling and keep medication in original packaging when practical.
| Item | Why pack it | Tip for European travellers |
|---|---|---|
| Oral rehydration salts | Help replace fluids and salts lost through diarrhoea or vomiting. | Buy a brand you recognise before departure and follow the packet instructions. |
| Hand sanitiser | Useful when soap and water are not available. | Pack a small bottle for day trips and transfers. |
| Basic anti-diarrhoeal medicine | May help in some situations, such as travel days, if suitable for you. | Ask a pharmacist at home when and when not to use it. |
| Paracetamol or your usual pain relief | Can help with aches or feverishness if appropriate for you. | Use only as directed and avoid mixing medicines without advice. |
| Thermometer | Helps you monitor whether you may have a fever. | Useful for families and travellers with health concerns. |
| Travel insurance details | Gives you access to medical assistance and advice lines if included. | Do not rely on European health cards outside Europe; check your policy before travel. |
| Reusable water bottle with safe refills | Helps you stay hydrated throughout the day. | Use only with safe drinking water sources. |
If you take prescription medication, bring enough for your trip and allow for possible delays. Travellers with allergies, digestive conditions or special diets should also carry a short written note with key medical details.
What to do if Bali belly happens
Start with hydration
If symptoms begin, the first priority is fluids. Sip safe water often, even if you do not feel like drinking much. Oral rehydration salts can be useful, especially if there is frequent diarrhoea, vomiting or heavy sweating. Follow the instructions on the packet.
Avoid assuming that one product is a quick bali belly cure. Recovery depends on the cause and your overall condition. The safest approach is to manage dehydration risk and seek advice if symptoms are concerning.
Rest and eat gently
Reduce activity plans for the day. Choose simple foods if you feel hungry, such as plain rice, toast, bananas, soup or other mild options that suit you. Avoid alcohol and very rich, oily or spicy meals until you feel better.
Speak to a pharmacist or doctor when needed
Pharmacies in Bali can often advise on basic stomach complaints, but a doctor is more appropriate if symptoms are strong, unusual or not improving. Your travel insurance provider may also have a medical assistance line that can direct you to suitable care.
| Situation | Practical response |
|---|---|
| Mild diarrhoea but you can drink | Rest, use safe fluids and oral rehydration salts as directed, and monitor symptoms. |
| Vomiting makes it hard to keep fluids down | Take small sips frequently and seek medical advice if it continues. |
| Blood in stool, severe pain or a high fever | Contact a doctor or urgent medical service promptly. |
| Signs of dehydration, confusion, fainting or extreme weakness | Seek urgent medical help. |
| Symptoms persist or keep returning | Arrange medical assessment rather than continuing to self-treat. |
Should you take antibiotics for Bali belly?
Do not self-prescribe antibiotics. Traveller’s diarrhoea can have different causes, and antibiotics are not always appropriate. Taking the wrong medicine can be ineffective and may create other problems.
If you are worried about bacterial infection or severe symptoms, speak to a doctor. Some travellers with particular medical risks may be given a plan by their doctor before travel, but that should be personalised advice.
Who should be extra cautious?
Most healthy adults can manage mild stomach upset with rest and hydration, but some travellers should take extra care and seek advice earlier.
- Families travelling with babies or young children.
- Pregnant travellers.
- Older travellers.
- People with diabetes, kidney disease, inflammatory bowel disease or other chronic conditions.
- Immunocompromised travellers.
- Anyone who becomes weak, confused, faint or unable to keep fluids down.
If you are in these groups, consider speaking with a travel clinic before leaving Europe and make sure your insurance covers medical care in Indonesia.
Practical tips for European travellers in Bali
Plan for the first 48 hours
After a long journey from Europe, it is tempting to pack the first day with beach clubs, sightseeing and spicy meals. A gentler start often works better. Hydrate, sleep, eat simply and allow your body to adjust to the heat.
Check your travel insurance before departure
Medical care abroad can involve upfront payment or insurer approval, depending on the situation and policy. Save your insurer’s emergency number offline and keep a copy of your policy details in your phone and email.
Bring familiar supplies rather than searching while ill
You can buy many basic items in Bali, especially in tourist areas, but it is easier to have a small kit already packed. This matters most if you arrive late, stay in a quieter area or have specific brand preferences.
Be practical when moving between areas
If you feel unwell, avoid long transfers, boat trips or remote day tours until you recover. Choose accommodation where you can rest comfortably and access help if needed.

Common mistakes to avoid
- Ignoring early dehydration: Waiting too long to drink or use rehydration salts can make you feel worse.
- Using anti-diarrhoeal medicine automatically: It may not be suitable in every case, especially with fever or blood in stool. Ask a pharmacist or doctor if unsure.
- Eating heavy meals too soon: Give your stomach time to settle before returning to rich or spicy foods.
- Assuming all stomach illness is Bali belly: Severe or unusual symptoms need medical assessment.
- Travelling without insurance details: Keep emergency contacts accessible offline.
