Bali Belly: What It Is, Symptoms, Treatment and How to Avoid It (Complete Guide)

Bali Belly is the digestive nightmare every traveler wants to avoid in Indonesia. This guide covers what it is, its symptoms, how long it lasts, how to treat it, and the best tips to prevent it before and during your trip.

What Is Bali Belly?

Bali Belly is essentially traveler’s diarrhea, a temporary digestive issue caused by consuming contaminated food or water in Bali. Locals develop a natural immunity to the microorganisms on the island, but a visitor’s stomach is not prepared for them. Even reputable restaurants can inadvertently introduce bacteria that make you sick.

Symptoms of Bali Belly

The most common symptoms include:

Diarrhea: Frequent and urgent, it’s often the first sign something is wrong.
Stomach cramps: Painful cramping sensation in the abdomen.
Nausea and vomiting: May occur in more severe cases.
Mild fever: Sometimes your body responds with a slight rise in temperature.

Where Does Bali Belly Come From?

Here are the main causes to watch out for:

Tap water: Do not drink it, not even for washing fruit or brushing your teeth. It may contain bacteria such as E. coli or other pathogens capable of disrupting your digestive system.
Food hygiene: Undercooked food, improper storage, or handling with unwashed hands all contribute to Bali Belly. Street food stalls are particularly susceptible, even when the food looks delicious.
Local bacteria: Bali residents have built up natural immunity to local microorganisms, but your stomach has not. Even well-known restaurants may inadvertently cause issues.

How Long Does Bali Belly Last?

In most cases, Bali Belly lasts between 1 and 3 days. With proper hydration, rest, and a bland diet, symptoms gradually improve. If there is no improvement after 3 days, or if you experience high fever, blood in your stools, or severe dehydration, it is important to see a doctor.

Practical Tips to Avoid Bali Belly

Avoid tap water: Drink only bottled water, even for brushing your teeth.
Stay hydrated: Drink bottled water in small amounts throughout the day to prevent dehydration.
Skip the ice: Refuse ice in drinks unless you are certain it was made with filtered water.
Be careful with juices: They can be made with unfiltered water or ice. Always ask how they are prepared before ordering.
Wash your hands regularly: Before every meal, especially after handling money or touching public surfaces. Carry hand sanitizer just in case.
Pack basic medication: Bring stomach medication, activated charcoal, and electrolytes as a precaution.
Strengthen your gut flora: Take probiotics before your trip to help your digestive system adjust to new bacteria.
Check restaurant reviews: Eat at well-rated places and avoid dubious street food vendors.
