Travel diarrhea is a common malady that can strike anyone who is on the move. It is characterized by loose stools, stomach cramps, and an upset stomach. There are various synonyms for this condition, including traveler's diarrhea, Montezuma's revenge, Delhi belly, and Aztec two-step. These terms are used to describe the same underlying condition that occurs when a traveler comes in contact with contaminated food or water in a foreign country. While the symptoms are mostly mild and go away on their own, it is important to stay hydrated and seek medical attention if they persist. To avoid travel diarrhea, it is recommended to stick to bottled water, fresh fruits and vegetables, and cooked foods.
