Tips to avoid traveler’s diarrhea on your next holiday

The etiology of traveler’s diarrhea (TD) often varies by region of travel, but is most commonly caused by bacterial enteropathogens. Although viral and parasitic infections can cause TD they are less commonly seen. The most common bacterial strain linked to TD is Escherichia coli, which can be found in none-purified water sources. However, both food and water can be the source of an infection.

The diagnosis of TD involves both clinical and laboratory assessment. Signs and symptoms include: loose or watery stools beginning 24-72 hours after consumption of contaminated food or water (severity can vary), nausea, vomiting, abdominal cramps and fecal urgency. TD is typically self-limiting and may take anywhere from 3 to 5 days to achieve symptom relief.

Some risk factors to be aware of that my increase your chances of contracting traveler’s diarrhea include:

  • Immunodeficiency state
  • Chronic gastrointestinal disease
  • Young age
  • Drinking untreated or none bottled water
  • Use of acid-blocking drugs 

    The following red flags are symptoms that will require immediate medical care:

    • Bloody diarrhea
    • High fever
    • Jaundice (yellowing of skin)
    • Enlarged lymph nodes
    • Rash
    • Neurological symptoms

              • Oral rehydration and electrolyte replacement
              • Antibiotics including ciprofloxacin and azithromycin are commonly used in the treatment of TD
              • Antimotility agents such as loperamide are often prescribed to provide symptomatic relief
              • Several natural antimicrobials have shown great benefit in the treatment of TD, the various options can be discussed with a naturopathic doctor
              • Soothing teas including chamomile and ginger tea can help to ease GI discomfort
