4 facts about the ways that probiotics and bismuth can prevent traveler’s diarrhea

If you’ve ever traveled to a new country and spent more time in the bathroom than sightseeing, you are not alone. Traveler’s diarrhea, often called TD, is a common issue, especially in areas with food and water standards different from those you’re used to. Many of the patients at Atlantic Gastroenterology of Brooklyn, New York, are looking for ways to prevent traveler’s diarrhea to ensure a more enjoyable trip, but might have questions about solutions like probiotics or bismuth subsalicylate. Dr. Alexander Shapsis can help educate you on these solutions for TD and whether or not they work as a preventative before travel.

1.Bismuth subsalicylate can be a decent defense

Bismuth subsalicylate, the active ingredient in products like Pepto-Bismol, has cut the possibilities of getting traveler’s diarrhea by about 50%.

How it works: It helps by fighting off bacteria and reducing inflammation in your gut.

How to take it: The recommended amount is four daily doses, usually taken with meals and at bedtime.

What the studies say: Both the CDC and the American College of Gastroenterology (ACG) support its use, especially in high-risk areas like parts of Mexico and Central America.

Side effects to be aware of: You might notice your tongue or stools turning black, and in some cases, patients might experience constipation, nausea, or ringing in the ears.

2. Probiotics are not nearly as promising

You may have heard that probiotics, like those in yogurt or supplements, help keep your gut healthy. However, the evidence is weak and inconsistent regarding the prevention of traveler’s diarrhea.

What the experts say: The ACG and CDC do not recommend using probiotics for this purpose.

Why not? Studies show mixed results. Some strains, like Saccharomyces boulardii, might help, but not enough to confidently say they work.

Bottom line: They’re safe for most people, but probably won’t stop you from getting sick while traveling.

3. Ways to reduce the risk of developing traveler’s diarrhea before and during your traveling experiences

There are several ways to reduce the risk of developing traveler’s diarrhea before and during your travels. Here are some tips recommended by Dr. Shapsis and his team:

• Be cautious with food and water. Consuming contaminated food and water is one of the primary causes of traveler’s diarrhea. To minimize this risk, it is important to be cautious about what you eat and drink while on the go. Avoid tap water, ice cubes, raw fruits and vegetables, and uncooked meat or seafood.
• Stick to bottled or boiled water. As mentioned above, tap water can be a major source of contamination. Always opt for bottled or boiled water instead. Make sure the bottle is sealed when you buy it.
• Wash your hands often. Proper hand hygiene is essential in preventing traveler’s diarrhea. Before and after eating, after using the bathroom, and as needed, wash your hands with soap and water.
