Nasal Congestion

What Causes Nasal Congestion?

Nasal congestion can have various causes, ranging in severity from 'troubling' to 'serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose nasal congestion, 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 "nasal congestion" as a symptom.  Here are eight possibilities:
  • Vasomotor Rhinitis
  • Mercury Toxicity
  • Chronic Fatigue-Fibromyalgia
  • Sarcoidosis
  • Milk Allergy
  • Indoor Allergies
  • General Toxicity
  • Vitamin Pantothenic Acid Need

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:
occasional itchy eyes
multiple swollen axillary nodes
history of adult allergies
morning stiffness without pain
slight moodiness
minor pain in cold/cool/damp weather
vision disturbances
frequent colds/flus
loss of appetite
recurrent bronchitis
unsound sleep
somewhat disturbed sleep
... and more than 100 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of nasal congestion:
Cause Probability Status
Milk Allergy 95% Confirm
Sarcoidosis 14% Unlikely
Vitamin Pantothenic Acid Need 14% Unlikely
Indoor Allergies 4% Ruled out
Chronic Fatigue-Fibromyalgia 0% Ruled out
Mercury Toxicity 0% Ruled out
Vasomotor Rhinitis 0% Ruled out
General Toxicity 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Nose/Smell Symptoms section of the questionnaire, The Analyst™ will ask the following question about nasal congestion:
Do you suffer from nasal congestion (blocked nose) or post-nasal drip?
Possible responses:
→ No / don't know
→ Occasionally / moderately
→ Often / severely
Based on your response to this question, which may indicate nasal congestion, The Analyst™ will consider possibilities such as:
Mercury Toxicity (Amalgam Illness)

Mild nasal congestion / stuffy nose can be a sign of mercury toxicity.
