How Travellers Can Stay Healthy in Bali Avoiding Bali Belly and Enjoying Every Moment of Their Trip

Published on December 14, 2025

Bali remains a top choice for travellers seeking sun-soaked beaches, lush landscapes, cultural experiences, and budget-friendly luxury. Its warm tropical climate, affordable resorts, and vibrant food and drink scene attract millions of visitors each year. From yoga retreats and wellness escapes to lively nightlife and scenic adventures, the island offers a diverse range of experiences for every type of traveller.

Yet amid the allure of Bali’s beaches and temples, one issue continues to trouble visitors: “Bali belly.” While the term is informal, the illness is very real and can quickly turn a dream holiday into an uncomfortable ordeal. Awareness and preparation are essential for enjoying the island without health disruptions.

Understanding the Condition

Bali belly is essentially a form of traveller’s diarrhoea. It occurs when the digestive system reacts to unfamiliar bacteria, viruses, or parasites commonly present in food or water. Although not unique to Bali, the island’s reputation as a popular holiday destination has made the term widely recognised among international visitors.

The illness typically arises after consuming contaminated food or beverages. Bacteria are the most common culprits, but viruses and parasites can also trigger symptoms, especially when illness persists beyond a few days. Individual immune responses, dietary habits, and overall health influence how severely someone is affected.

Common Symptoms

The signs of Bali belly vary in intensity. Mild cases may cause temporary discomfort, while more severe instances can leave travellers confined to their accommodation. Typical symptoms include frequent watery stools, abdominal cramps, bloating, nausea, vomiting, and fatigue. The tropical heat and humidity can worsen dehydration, making prompt attention and hydration essential.

Even short-lived symptoms can disrupt travel plans, preventing participation in activities like sightseeing, trekking, or long-distance excursions. Early recognition and management of symptoms help ensure a faster recovery and a smoother holiday experience.

Causes and Exposure

The primary source of Bali belly is contaminated food or drink. Tap water is generally unsafe for consumption, and exposure may occur through drinking it, consuming ice made from untreated water, or eating produce washed with unsafe water. Raw vegetables, salads, undercooked meat or seafood, and improperly stored food pose additional risks.

Unintentional exposure can occur through everyday actions such as brushing teeth with tap water, swallowing water while swimming, or handling food without proper hand hygiene. Sudden changes in diet, including trying rich, spicy, or unfamiliar dishes, can also disrupt digestion and increase vulnerability to illness.

A Global Travel Issue

Traveller’s diarrhoea is a common problem worldwide, occurring in many regions where food, water, or sanitation standards differ from what travellers are accustomed to. Bali belly is simply the local term for this global phenomenon, highlighting the importance of food and water safety in any travel destination.

Preventing Bali Belly

While it is impossible to completely eliminate the risk, travellers can take steps to protect themselves. Recommended precautions include:

• Drinking only sealed bottled or filtered water
• Avoiding ice unless it is confirmed safe
• Washing hands regularly or using hand sanitiser before eating
• Choosing freshly cooked, hot meals
• Being cautious with raw vegetables, unpeeled fruits, salads, and unpasteurised dairy

Many travellers also carry oral rehydration solutions, probiotics, and basic anti-diarrhoeal medication as a precaution. Being mindful of food and drink choices allows visitors to enjoy local cuisine without compromising health.

Seeking Medical Attention

Most cases of Bali belly improve within a few days without medical treatment. However, medical care is necessary if symptoms are severe, prolonged, or accompanied by high fever, blood in stools, or signs of dehydration. Bali has a range of medical clinics and pharmacies that cater to international visitors, making professional care readily accessible.

Travelling Smart

Bali’s natural beauty, cultural richness, and variety of experiences make it an unforgettable destination. Understanding the risks associated with Bali belly allows travellers to make informed choices, reduce health risks, and focus on enjoying their holiday.

Preparation and awareness are the keys to a comfortable and memorable trip. By staying vigilant about food and water safety, maintaining good hygiene, and carrying essential medical supplies, visitors can fully embrace Bali’s beaches, temples, and vibrant culture without unnecessary interruptions.
