Traveler's diarrhea is a disorder that causes loose stools and abdominal cramps. It is caused by eating food or drinking water that is contaminated.
Traveler's diarrhea is not a serious condition although it can be unpleasant. It is caused by visiting places where climate, social conditions or sanitary conditions and practices are diffent from those at home.
Being careful about eating or drinking certain foods and drinks can help to reduce the risk of traveler's diarrhea. Most cases traveler's diarrhea don't require treatment. Medications can be prescribed if diarrhea persists.
Traveler's diarrhea usually begins abruptly during a trip or after returning from the trip. Most cases resolve within a few days without treatment.
Traveler's diarrhea is usaully caused by ingesting food or water that is contaminated with organisms, such as bacteria, viruses and parasites, from feces.
When these organisms enter the digestive tract they can overpower the digestive body's defense mechanisms. This leads to the development of signs and symptoms of traveler's diarrhea.
The most common cause of traveler's diasease is enterotoxigenic Escherichia Coli (ETEC) bacteria. ETEC attach to the lining of the intestines and release toxins that cause diarrhea snd abdominal cramps.
Natives are not affected because their digestive system is accustomed to the bacteria and developed immunity to them.
Stress can also cause traveler's diarrhea.
Traveler's diarrhea usually resolves on itself and does not require treatment. Patients are required to take lots of fluids to prevent dehydration.
Dehydration can be treated by administering an oral rehydration salt (ORS). This solution contains water and salts in a specific proportion to replace both water and minerals lost. An ORS may also contain glucose to stimulate absorption in the intestines. ORS is availabel as a bottled product and as packets of powder thaat can be dissolved in water.
In emergency cases where ORS is not available, it can be made by mixing:
1/2 teaspoon salt
1/2 teaspoon baking soda
4 tablespoons of sugar
1 liter of safe drinking water
If symptoms do not improve, medications can be used to relieve symptoms.
Medications that can be used include:
Anti-motility agents, such as loperamide (Imodium AD) and drugs containing diphenoxylate (Lamotil, Lonox). These drugs prompt but temporary relief by reducing muscle spasms in the gastrointestinal tract. These drugs are not recommeded for children or people with fever or bloody diarrhea.
Bismuth subsalicylate (Pepto-Bismol), an over-the-counter medication that decreases the frequency of stools and also reduces the duration of traveler's diarrhea.
Antibiotics, which may be given if a person has more than four stools a day or severe symptoms, such as fever or blood, pus or mucus in the stools.
Avoiding the consumption of food from street vendors.
Avoiding unpasturized milk and diary products, including ice cream.
Avoiding raw and uncooked meat, fish or shellfish.
