What Is Bali Belly?

“Bali Belly” is a term used to describe travelers’ diarrhea, a common issue for visitors to Bali. It’s usually caused by unfamiliar bacteria or viruses entering the digestive system through food, water, or contact with contaminated surfaces. Symptoms can include diarrhea, nausea, vomiting, stomach cramps, and dehydration. While Bali Belly is typically mild, it can be inconvenient and disrupt travel plans.

The main sources of contamination are bacteria (E. coli, Salmonella), viruses (norovirus), and parasites (Giardia), which are naturally present in the environment. However, these are not exclusive to Bali—they exist in many countries, especially in tropical regions. Since visitors’ immune systems are not accustomed to Bali’s local microbes, they may be more sensitive to changes in diet and water sources.

 

 

Why Do Tourists Experience Bali Belly, but Locals Don’t?

While travelers may experience stomach issues, locals rarely get Bali Belly because their bodies have adapted over time. This is not because Bali is unsafe, but simply because their immune systems and digestive systems are accustomed to the local environment.

 

1. Gut Adaptation Over Time

 

Locals have been exposed to Bali’s natural bacteria from a young age, allowing their digestive systems to adapt. This long-term exposure helps build stronger immunity to common microbes.

 

2. A Naturally Balanced Gut Microbiome

 

Balinese and Indonesian people regularly consume fermented foods such as tempeh and jamu (a traditional herbal drink), which support gut health. These foods contain probiotics and natural antibacterial properties, helping to maintain a balanced digestive system.

 

3. Familiarity with Local Food and Water

 

Since locals consume food and water in Bali every day, their digestive systems recognize and tolerate local ingredients more easily. Meanwhile, travelers, especially those from countries with highly sanitized food systems, may find their gut reacting differently to new bacteria.

 

4. Awareness of Where to Eat and Drink

 

Locals know which places follow the best hygiene standards and which dishes suit their digestion. They also tend to eat freshly prepared meals rather than pre-packaged or reheated food, which helps reduce the risk of bacterial growth.

 

Can Tourists Adapt Like Locals?

 

While travelers won’t build full immunity in a short time, they can reduce the risk of Bali Belly by:
✔ Trying local fermented foods like tempeh and jamu to support digestion
✔ Gradually introducing local dishes rather than eating everything at once
✔ Choosing safe and hygienic food and drink options, just like locals do

By following some simple precautions, you can enjoy Bali’s delicious food and drinks while staying healthy.

1. Drink Safe and Filtered Water

 

- Choose bottled or filtered water rather than tap water.

- Few cafes and hotels provide free filtered water refills—a more eco-friendly and safe option.

- Use boiled water for tea or coffee, as heat kills bacteria.

 

2. Eat Fresh, Cooked Food 

 

- Choose meals that are freshly prepared and served hot.

- Street food is safe if cooked fresh—watch the cooking process and choose stalls with high customer turnover.

- Avoid buffet food that has been sitting for hours.

 

3. Try Local Remedies for Gut Health

 

- Tempeh (fermented soybean) is a natural probiotic that supports digestion.

- Jamu (a herbal drink made from turmeric and ginger) is known for its antibacterial and anti-inflammatory properties.

- Coconut water is a natural electrolyte that helps keep you hydrated.

 

4. Maintain Proper Hand Hygiene

 

- Wash hands with soap and water regularly, especially before eating.

- Use hand sanitizer when soap isn’t available.

 

If you're seeking herbal medicines to address Bali Belly, several locally available products in Bali can help alleviate symptoms:

Diapet
 

A popular over-the-counter herbal supplement designed to combat diarrhea and nausea. Diapet contains natural ingredients like yellow guava extract, turmeric (curcumin), Terminalia chebula (for liver support), and pomegranate (with antimicrobial properties). It's widely available in local pharmacies and convenience stores.

 

Norit


Activated charcoal tablets that may help absorb toxins in the digestive system, potentially reducing the severity of Bali Belly symptoms. Norit is commonly found in supermarkets, pharmacies (known locally as 'apotek'), Guardian, Watson, and mini-marts like Circle K, Indomaret, or Alfamart.

 

Tolak Angin


A traditional Indonesian herbal remedy, often used to combat symptoms of 'masuk angin' (a local term for feeling unwell due to wind exposure). While it's primarily used for colds and fatigue, some travelers find it helpful for digestive discomfort. Tolak Angin is available in liquid sachets and can be purchased over the counter in pharmacies and convenience stores.

 

Jamu

A traditional Indonesian herbal drink made from natural ingredients like turmeric, ginger, and tamarind. Jamu is believed to boost the immune system and aid digestion. It's widely available in local markets, health food stores, and some cafes.

 

Before using any herbal remedies, it's advisable to consult with a healthcare professional, especially if you have existing health conditions or are taking other medications. Additionally, ensure that any product you purchase is from a reputable source to guarantee its quality and safety.

Bali Belly can disrupt your trip, but it’s avoidable with the right precautions. Being careful with what you eat and drink—such as choosing bottled water, eating freshly cooked meals, and avoiding raw or unwashed produce—greatly reduces the risk. Practicing good hygiene, like washing hands regularly and using hand sanitizer, also helps prevent exposure to harmful bacteria.

With these simple steps, you can enjoy Bali’s food, culture, and beautiful surroundings without stomach troubles getting in the way. A little caution ensures a smoother and more enjoyable travel experience. Safe travels!
