Newswise — Spring weather is here, as well as the travel season. And with all the different locations and exotic foods, travelers can suffer from a bout of diarrhea.
Fortunately, most people experience a mild form and respond well to regular fluid intake and anti-diarrhea medication, says Dr. Luis Lara, assistant professor of internal medicine in digestive and liver diseases at UT Southwestern Medical Center at Dalals. Those with underlying diseases, very young or elderly are at greater risk and may require antibiotics or other medications.
"An estimated 20 percent to 60 percent of travelers to developing countries will come down with diarrhea, making it the No. 1 ailment of travel, and it can manifest up to two weeks after returning home," says Dr. Lara. "Despite common knowledge that travelers' diarrhea is acquired by transmission from food and water consumption, many people do not pay attention to what they eat and drink." Preventing travelers' diarrhea begins with common sense measures to avoid exposure.
"The most important component is rehydration, and an oral solution provided through the World Health Organization is widely available and superior to sports drinks," says Dr. Lara. "Patients should eat as tolerated, as there is no good evidence to support the often-advised restricted diet. High-risk patients or those with concerns about becoming ill and obtaining medical service and products while abroad should take a first aid kit."
