Travel Diarrhea: Causes, Symptoms, Treatment, and Prevention for Travelers

Travel diarrhea is one of the most common health issues experienced by travelers, especially when visiting tropical destinations. Changes in food, water, hygiene standards, and climate can expose your digestive system to unfamiliar bacteria, viruses, or parasites—often leading to uncomfortable digestive symptoms.

In Bali, travel diarrhea is frequently referred to as Bali Belly, a condition many visitors experience during their stay due to food or water contamination. Understanding how to prevent, recognize, and treat travel diarrhea can help you recover faster and continue enjoying your trip.

Travel diarrhea is a digestive infection characterized by frequent loose or watery stools that occur during or shortly after traveling. It is most commonly caused by consuming contaminated food or unsafe drinking water in regions where sanitation standards differ from those in your home country.

Travel diarrhea may be triggered by:

1. Contaminated Food

Undercooked meat, raw seafood, unwashed fruits and vegetables, or improperly handled street food are common sources. These are also leading causes of Bali Belly among travelers.

2. Unsafe Drinking Water

Tap water, ice cubes, or beverages made with untreated water can carry harmful bacteria and parasites.

3. Bacterial, Viral, or Parasitic Infections

Bacteria such as E. coli, Salmonella, and Campylobacter are the most common causes, followed by viruses and parasites—especially during longer stays.

Symptoms usually appear within a few days of exposure and may include:

• Frequent loose or watery stools
  
• Abdominal cramps or bloating
  
• Nausea or vomiting
  
• Fever
  
• Fatigue and weakness
  
• Signs of dehydration 

In more severe cases, blood or mucus may appear in the stool.

Although many cases are mild, untreated travel diarrhea can lead to serious complications. Dehydration is the most common risk, especially in hot climates like Bali. Severe dehydration can cause dizziness, electrolyte imbalance, and weakness—making prompt treatment essential.

Home Care for Mild Symptoms

• Drink plenty of fluids or oral rehydration solutions
• Rest and avoid spicy, oily, or heavy meals
• Consume bland foods such as rice, bananas, and toast
• Avoid alcohol and caffeine

Medical Treatment

If symptoms worsen or do not improve, medical care is recommended. Treatment may include:

• Prescription medication if a bacterial infection is suspected
• Anti-diarrheal treatment when appropriate

IV therapy for rapid hydration and recovery

Seek medical attention if you experience:

• Diarrhea lasting more than 48–72 hours 
• High fever 
• Bloody stools
