Traveler’s Diarrhea: What Is It & How to Avoid It?

It often happens during a trip, especially with changes in climate or diet, that you end up spending a few tough days running to the bathroom before things go back to normal. In most cases, it is nothing serious: this issue is known as traveler’s diarrhea¹.

Understanding Traveler's Diarrhea

What is Traveler's diarrhea?

Traveler’s diarrhea is caused by certain pathogens. Most often, it’s usually a bacterial infection, but can be viral or parasitic, linked to food and water—often due to poor hygiene practices in some tropical countries¹ ² ³. Even though it is very unpleasant, it is generally a mild illness.

It’s the most predictable travel-related condition, affecting 40 to 60%¹ of all travelers (about 10 million people each year), who experience stomach issues during their trip ranging from mild discomfort to acute episodes.

The change in environment increases the likelihood of contracting this infection. While traveler’s diarrhea symptoms are not age-specific, it tends to be more common in young adults. Its prevalence depends on several factors: the destination (tropical countries are more at risk, though it can happen anywhere), the season, and age⁴.

Symptoms of Traveler's diarrhea

Symptoms vary. Affected individuals typically experience up to five loose or watery bowel movements per day, often accompanied by abdominal cramps, nausea, or vomiting⁵ ⁶.

These symptoms usually appear within the first week of travel and last about four to five days⁵ ⁶.
If symptoms persist or worsen — with the appearance of fever, blood in the stool, or bloating — you should consult a doctor⁷ ⁸.

How to Prevent Traveler's Diarrhea: Prevention Tips

Adopt simple habits to prevent traveler’s diarrhea. You should:

Keep Your Hands Clean

Always wash your hands thoroughly with soap and water or use a hand sanitizer after using the toilet and before eating⁹. This removes viruses, toxins, and microbes and helps limit their spread.

Eat and Drink Safely

Eat cooked foods served hot, fruits and vegetables you’ve peeled yourself, and pasteurized dairy products.
Avoid food served at room temperature, raw or undercooked meat or fish, ice cream, and shellfish¹⁰.
Drink only sealed bottled water, ice made from bottled or disinfected water, and carbonated drinks in sealed containers¹¹ ¹².
Also, brush your teeth with bottled water.

Pack a Proper Travel First Aid Kit

Bring essential medications, especially those for diarrhea and dysentery, oral rehydration salts, and hand sanitizers or alcohol-based hand solutions¹². Ask your pharmacist or consult your doctor before traveling abroad if you’re unsure what to include in your first aid kit.

If you’re going to a country with specific health risks, it may be useful to consult a travel medicine specialist¹³. They can advise you on vector-borne disease prevention, malaria areas, and necessary vaccines or antibiotics.

What to Do If You Get Traveler's Diarrhea?

If you suffer from traveler’s diarrhea, treat it like any other case of acute diarrhea:

Stay Well Hydrated

Diarrhea, vomiting, and tropical climates cause significant water and mineral loss from the body. It’s essential to replace these losses quickly by drinking often: salted and sweetened drinks, plain or sugary water, vegetable broth, white-rice water and herbal teas. Avoid alcohol, coffee, and cold drinks.

For mild to moderate dehydration, oral rehydration solutions (ORS) are recommended—they contain essential elements needed during diarrhea¹⁴ ¹⁵. Usage guidelines may vary by country: seek advice from a healthcare professional.

For severe dehydration, bloody stools, or persistent fever, consult a doctor immediately⁷ ¹⁶.

Children and older adults are more vulnerable to dehydration⁸. If a person is lethargic, not eating or drinking, not urinating, or has a high fever, medical consultation is urgent.

Adjust Your Diet

Take care with what you eat. Opt for small, light meals to avoid overloading your digestive system. Choose easy-to-digest foods and avoid spicy dishes that can irritate the intestines¹⁷.

Treat the Diarrhea

Traveler’s diarrhea must be treated like any other acute diarrhea to prevent dehydration and mineral loss.

In addition to the hygiene and dietary recommendations above, symptomatic treatment is advised. Taking adsorbents and intestinal anti-secretory agents can help relieve symptoms. Some probiotic strains may also be helpful¹⁸ ¹⁹.

If symptoms persist, consult a doctor or pharmacist for the most appropriate care¹⁶.
