- Traveler’s diarrhea, also called Montezuma’s revenge or traveler’s tummy, is a common stomach upset most often caused by new bacteria in contaminated food and drinks, and disrupted routines and poor sleep can add to the risk.
- Symptoms vary in severity and length, with diarrhea often joined by stomach cramps and vomiting, and sometimes by fever and muscle aches.
- Frequent hand-washing with soap and warm water and sealed bottled water, even for brushing teeth, are two of the simplest defenses, and skipping ice avoids water of unknown origin.
- Food that is cooked and served hot is the safest bet, so skip buffet dishes that may have sat out and wash or peel fruit and vegetables before eating them.
- Getting enough sleep and staying active support digestive health on the road, since long stretches of sitting can contribute to travel-related constipation.
- Treatment for mild cases centers on replacing lost fluids with bottled water or an electrolyte drink and resting while the body recovers, and a doctor or pharmacist can advise on over-the-counter remedies.

Five simple steps keep your gut happy on your next holiday, so the memories stay good ones!
What Are Symptoms of Traveler’s Tummy?
Traveler’s diarrhea, also known as Montezuma’s revenge, strikes quite many travelers. Common causes include new bacteria in contaminated food and drinks, along with disrupted schedules and poor sleep that come with a trip. Gut infection symptoms vary in severity and length, and they may include the following:
- Fever
- Muscle aches
- Stomach cramps
- Vomiting
- Diarrhea
- Loss of appetite
- Unintentional weight loss
Five Tips to Prevent Traveler’s Diarrhea
Travel should fill your days with good memories. These five proven tips help you prevent traveler’s diarrhea and keep your adventures worry-free.
1. Practice Good Hygiene
Good hygiene is one of the most important defenses against Montezuma’s revenge. Frequent, thorough hand-washing clears away germs, one of the big culprits of traveler’s diarrhea. Use soap and warm water, particularly after you’ve used the bathroom and before you eat. Keep an alcohol-based hand sanitizer handy and apply it regularly.
2. Get Plenty of Sleep
Sleep is one of the most underestimated elements of digestive health, and it often takes a hit on the road. With so much to see and do, and jet lag throwing a wrench in your schedule, rest slips down the list.
Lack of sleep shows up throughout your body, from your mood to your muscles. Plan for a solid night’s rest, whether that means packing a white noise machine or an eye mask. Then make those zzz’s a priority.
3. Make Wise Water Choices
Staying well hydrated is essential to a healthy gut on the road. At home, you may pour water straight from the tap, but safe drinking water isn’t always available everywhere. Instead, choose sealed bottled water, including when brushing your teeth. Ice may have been made from contaminated water, so skip it when dining out.
4. Keep Moving
Long stretches of sitting, such as a long-haul flight or a bus ride across country, can contribute to travel-related constipation. Stay active during your trip to keep things moving. No gym required, so walk whenever you can. As a bonus, exploring on foot is a lovely way to see the sights!
5. Opt for Cooked, Clean Food
Among the greatest joys of traveling is experimenting with new cuisines, and when done mindfully, it need not bring on Montezuma’s revenge. One of the most common bacterial pathogens, Salmonella, is difficult to detect as contaminated foods rarely carry a giveaway smell or taste.
Stick with foods that are cooked and still hot, and steer clear of buffet dishes that have been sitting out for an unknown amount of time. Fruit and vegetables are smart choices, as long as they are washed in clean water or peeled first.
Think about any trigger foods that cause trouble at home and decide whether they’re worth the risk. Lastly, consider opting for fiber-rich foods to boost hydration and help you stay regular on the road.
Enjoy a Healthy, Happy Holiday
Hit by the uncomfortable symptoms of traveler’s tummy? Simple treatments can ease the discomfort, whether you’re dealing with diarrhea or indigestion. Common measures include the following:
- Using over-the-counter remedies, such as antidiarrheal medication for diarrhea or antacids for indigestion, after checking with a doctor or pharmacist.
- Replacing lost fluids by hydrating with bottled water or an electrolyte sports drink.
- Resting well and taking it slow as you recover.
Many simple steps minimize the risk of traveler’s diarrhea and keep your vacation healthy and stress-free. Clean hands and safe food and water do most of the work, and good sleep and steady movement back them up, so Montezuma’s revenge has a hard time catching you.
When Your Stomach Stages a Protest
How long does traveler’s diarrhea last?
Most cases clear up on their own within a few days, typically three to seven when bacteria are the cause. Plenty of fluids and rest help the body recover.
When should you see a doctor for traveler’s diarrhea?
See a doctor right away if you have blood in the stool or a high fever, as well as vomiting that keeps fluids from staying down and signs of dehydration such as dizziness or very little urine. Symptoms that last more than a few days also deserve a call to a doctor. Antidiarrheal medication isn’t right when blood or fever is present, so check with a doctor or pharmacist first.
