What is Traveler’s Diarrhea and How Can You Prevent It?

Traveler’s diarrhea, a common concern for those exploring destinations like Vietnam, can disrupt your travel plans. SIXT.VN offers solutions to help you navigate these challenges, ensuring a smoother and more enjoyable experience. With the right precautions and support, you can minimize your risk and focus on creating unforgettable memories. Consider travel health, food safety, and safe drinking water to ensure a healthy trip.

1. What Exactly is Traveler’s Diarrhea?

Traveler’s diarrhea is a digestive tract disorder that causes loose, watery stools and stomach cramps, typically resulting from consuming contaminated food or water. Fortunately, it’s usually not serious, with most people recovering within a few days. However, it’s still unpleasant and can derail your travel plans.

Understanding the Gastrointestinal Tract

The gastrointestinal tract, which stretches from your mouth to your anus, includes the organs necessary for digesting food, absorbing nutrients, and processing waste. When you visit a place like Vietnam, where the climate and sanitary practices might differ from your home country, you face an increased risk of developing traveler’s diarrhea.

What Causes Traveler’s Diarrhea?

Traveler’s diarrhea is primarily caused by infectious agents such as bacteria, viruses, or parasites found in contaminated food and water. E. coli is a common bacterial culprit, but other pathogens can also be responsible.

2. What are the Symptoms of Traveler’s Diarrhea?

Symptoms of traveler’s diarrhea can appear suddenly during your trip or shortly after you return home. Most people recover within 1 to 2 days without treatment and completely recover within a week. However, multiple episodes can occur during a single trip.

Common Symptoms Include:

• Passing three or more loose, watery stools a day suddenly
• An urgent need to pass stool
• Stomach cramps
• Nausea
• Vomiting
• Fever

In some cases, people experience moderate to severe dehydration, ongoing vomiting, a high fever, bloody stools, or severe pain in the belly or rectum. If you or your child experiences any of these symptoms, or if the diarrhea lasts longer than a few days, it’s time to see a healthcare professional.

3. When Should I See a Doctor for Traveler’s Diarrhea?

Traveler’s diarrhea usually resolves itself within a few days. However, if symptoms persist or worsen, seeking medical attention is crucial. Symptoms may last longer and be more severe if caused by certain bacteria or parasites. In such cases, you may need prescription medicines to help you get better.

Guidelines for Adults:

• Your diarrhea lasts beyond two days.
• You become dehydrated.
• You have severe stomach or rectal pain.
• You have bloody or black stools.
• You have a fever above 102 F (39 C).

While traveling internationally, a local embassy or consulate may be able to help you find a well-regarded medical professional who speaks your language.

Special Considerations for Children:

Children are more vulnerable to dehydration from traveler’s diarrhea. Call a doctor immediately if your child exhibits any of the following:

• Ongoing vomiting.
• A fever of 102 F (39 C) or more.
• Bloody stools or severe diarrhea.
• Dry mouth or crying without tears.
• Signs of being unusually sleepy, drowsy, or unresponsive.
• Decreased volume of urine, including fewer wet diapers in infants.

4. What are the Primary Causes of Traveler’s Diarrhea?

While the stress of traveling or a change in diet may contribute, traveler’s diarrhea is most often caused by infectious agents — such as bacteria, viruses, or parasites. You typically develop traveler’s diarrhea after ingesting food or water contaminated with organisms from feces.

Why Locals Are Less Affected

Natives of high-risk countries often develop immunity to the local bacteria over time, which reduces their susceptibility to traveler’s diarrhea.

5. Who is at Risk of Developing Traveler’s Diarrhea?

Each year, millions of international travelers experience traveler’s diarrhea. According to the Centers for Disease Control and Prevention (CDC), high-risk destinations include areas of Central America, South America, Mexico, Africa, South Asia, and Southeast Asia.

Risk Factors to Consider:

• Young Adults: Traveler’s diarrhea is slightly more common in young adult tourists. Reasons why aren’t clear, it’s possible that young adults lack acquired immunity. They may also be more adventurous than older people in their travels and dietary choices, or they may be less careful about avoiding contaminated foods.
• People with Weakened Immune Systems: A weakened immune system due to an underlying illness or immune-suppressing medicines such as corticosteroids increases risk of infections.
• People with Certain Medical Conditions: People with diabetes, inflammatory bowel disease, or severe kidney, liver, or heart disease are more prone to infection or at risk of a more severe infection.
• People Taking Acid Blockers or Antacids: Acid in the stomach tends to destroy organisms, so a reduction in stomach acid may leave more opportunity for bacterial survival.
• Travel During Specific Seasons: The risk of traveler’s diarrhea varies by season in certain parts of the world. For example, risk is highest in South Asia during the hot months just before the monsoons.

6. What are the Potential Complications of Traveler’s Diarrhea?

The primary complication of traveler’s diarrhea is dehydration, as vital fluids, salts, and minerals are lost.

Dangers of Dehydration

Dehydration is especially dangerous for children, older adults, and people with weakened immune systems. Complications can include organ damage, shock, or coma.

Recognizing Dehydration:

• A very dry mouth
• Intense thirst
• Little or no urination
• Dizziness
• Extreme weakness

7. How Can I Effectively Prevent Traveler’s Diarrhea?

Prevention is key to enjoying your travels without the disruption of traveler’s diarrhea. The CDC recommends being vigilant about food and water safety.

Safe Eating Habits:

• Don’t consume food from street vendors.
• Don’t consume unpasteurized milk and dairy products, including ice cream.
• Don’t eat raw or undercooked meat, fish, and shellfish.
• Don’t eat moist food at room temperature, such as sauces and buffet offerings.
• Eat foods that are well-cooked and served hot.
• Stick to fruits and vegetables that you can peel yourself, such as bananas, oranges, and avocados. Stay away from salads and fruits you can’t peel, such as grapes and berries.
• Be aware that alcohol in a drink won’t keep you safe from contaminated water or ice.

Safe Drinking Habits:

• Don’t drink unsterilized water — from tap, well, or stream. If you need to consume local water, boil it for three minutes. Let the water cool naturally and store it in a clean covered container.
• Don’t use locally made ice cubes or drink mixed fruit juices made with tap water.
• Beware of sliced fruit that may have been washed in contaminated water.
• Use bottled or boiled water to mix baby formula.
• Order hot beverages, such as coffee or tea, and make sure they’re steaming hot.
• Feel free to drink canned or bottled drinks in their original containers — including water, carbonated beverages, beer, or wine — as long as you break the seals on the containers yourself. Wipe off any can or bottle before drinking or pouring.
• Use bottled water to brush your teeth.
• Don’t swim in water that may be contaminated.
• Keep your mouth closed while showering.

Water Purification Methods:

If it’s not possible to buy bottled water or boil your water, bring some means to purify water. Consider a water-filter pump with a microstrainer filter that can filter out small microorganisms. You can also chemically disinfect water with iodine or chlorine. Be sure to follow the directions on the package.

Additional Preventive Tips:

• Make sure dishes and utensils are clean and dry before using them.
• Wash your hands often and always before eating. If washing isn’t possible, use an alcohol-based hand sanitizer with at least 60% alcohol to clean your hands before eating.
• Seek out food items that require little handling in preparation.
• Keep children from putting things — including their dirty hands — in their mouths. If possible, keep infants from crawling on dirty floors.
• Tie a colored ribbon around the bathroom faucet to remind you not to drink — or brush your teeth with — tap water.

8. Are There Any Medications I Can Take to Prevent Traveler’s Diarrhea?

While antibiotics are generally not recommended for preventing traveler’s diarrhea due to the risk of antibiotic resistance, bismuth subsalicylate (the active ingredient in Pepto-Bismol) can be effective.

Considerations for Using Bismuth Subsalicylate:

• Dosage: Follow the instructions on the product label.
• Duration: Do not take for longer than three weeks.
• Contraindications: Do not take if you are pregnant or allergic to aspirin. Consult your doctor before taking if you are on anticoagulants.
• Side Effects: Common harmless side effects include a black-colored tongue and dark stools. In some cases, it can cause constipation, nausea, and, rarely, ringing in your ears (tinnitus).
