Bali Belly is the common name travellers use for diarrhoea during a trip to Bali. It is usually caused by contaminated food or water and often improves within a few days.
Common Bali Belly Symptoms
You may experience:
- Loose or watery diarrhoea
- Stomach cramps
- Nausea or vomiting
- Bloating
- Urgent bowel movements
- Fatigue or weakness
- Sometimes fever
The severity can vary. Some people recover quickly, while others may become dehydrated and require medical care.
What to Do
1. Rehydrate
ORS (oral rehydration solution) is the most important treatment because it replaces both fluids and electrolytes lost through diarrhoea and vomiting.
Take frequent small sips, especially if you feel nauseous.
2. Eat When You Can
You do not need to completely stop eating. Start with foods that are easy for you to tolerate, such as rice, bananas, soup, toast or crackers.
3. Be Careful With Medication
Loperamide can reduce diarrhoea in some adults, particularly when you need temporary symptom control.
However, do not rely on loperamide alone if you have blood in your stool or significant fever.
Antibiotics are not needed for every case of Bali Belly. They are generally reserved for selected cases of moderate-to-severe travellers’ diarrhoea and should ideally be prescribed after clinical assessment.
When Should You See a Doctor?
Seek medical attention if you have:
- Blood in your stool
- High or persistent fever
- Repeated vomiting or inability to drink
- Signs of dehydration
- Severe or worsening abdominal pain
- Severe or persistent diarrhoea
- Symptoms that are getting worse instead of better
Signs of dehydration include very little or dark urine, dizziness, marked weakness, excessive thirst and dry mouth.
Bali Belly Isn't Always Just Bali Belly
Diarrhoea with significant fever, severe abdominal pain, rash, bleeding or unusual weakness may require assessment for other illnesses that can occur in Bali, including dengue and other infections.
Can You Prevent Bali Belly?
You cannot eliminate the risk completely, but you can reduce it:
- Drink safe or sealed bottled water.
- Be cautious with ice when the water source is uncertain.
- Choose well-cooked food.
- Be careful with raw foods and salads.
- Wash your hands regularly.
- Carry ORS when travelling.
The Bottom Line
Most mild cases of Bali Belly improve with rest and good hydration. ORS is particularly useful when you are losing significant fluids.
If you develop dehydration, bloody diarrhoea, significant fever, persistent vomiting or severe abdominal pain, don’t simply wait it out—get medically assessed.
