Summer vacation may be over, but many of us are already thinking about our travel plans for the holiday season.  Those of you who've traveled abroad may have already experienced travelers' diarrhea at some point. And those of you who haven't yet, count yourself lucky. Travelers' diarrhea (or TD) is the most common illness in those who travel internationally, occurring in 20%-50% of all travelers to some extent.

Imagine being in a completely foreign country (which can be anxiety-provoking in and of itself) and feeling ill.  Being hit with abdominal discomfort, cramping, nausea, and diarrhea can surely dampen your sense of adventure, along with your ability to enjoy your trip.

If you know you’ll be traveling abroad, make sure you understand your risks for travelers' diarrhea and plan ahead.  Let’s discuss what it is, how to prevent it, and how to treat it.
