Traveler's diarrhea is diarrhea in people who travel to international destinations. It often happens in less developed countries.
The primary cause of traveler’s diarrhea is ingesting contaminated food or water. The substance carries bacteria, a virus, or a parasite that causes the diarrhea. Examples of agents that can cause the diarrhea include:
The pathogen that causes the infection will partly depend on the area of travel.
The most important risk factor for getting traveler’s diarrhea is the destination. Underdeveloped countries with unsafe water supplies pose the highest risk. The following factors increase your chance of getting traveler’s diarrhea. If you have any of these risk factors and plan to travel internationally, tell your doctor:
Symptoms can include:
You will be asked about your symptoms and medical history. A physical exam will be done.
A stool sample may be taken. This will allow your doctor to identify the pathogen.
Talk with your doctor about the best treatment plan for you. Your doctor may direct you to self-treat if you are travelling to certain countries and have sudden moderate to severe diarrhea. People who get traveler's diarrhea usually get better within 3-5 days even without treatment. Treatment options include the following:

Antibiotics may reduce how long symptoms last by 1-2 days. These antibiotics are only helpful for treating infections caused by bacteria.
Antimotility agents may help relieve symptoms of diarrhea. Examples of these medications include:
If you are diagnosed with traveler's diarrhea, follow your doctor's instructions.
