Sickness While Traveling Abroad

What Causes Travelers Sickness?

Travelers sickness can have various causes, just like most other symptoms.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • understand what's happening to your body
  • check your overall health status
  • identify any nutritional deficiencies

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose travelers sickness, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "travelers sickness" as a symptom.  Here are two possibilities:
  • Parasite Infection
  • Bacterial Dysbiosis

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
tetracycline use
PPI antacid use
diarrhea for 1-3 months
significant abdominal distension
history of dysentery
orange stool color
highly elevated eosinophil count
frequent postprandial somnolence
regular episodes of diarrhea
poor tolerance of sugars
frequent meal-related bloating
offensive-smelling stool
... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of travelers sickness:
Cause Probability Status
Parasite Infection 98% Confirm
Bacterial Dysbiosis 54% Possible
* This is a simple example to illustrate the process
