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:
  • Milk Allergy
  • Sarcoidosis
  • Indoor Allergies
  • Mercury Toxicity
  • Vasomotor Rhinitis
  • General Toxicity
  • Chronic Fatigue-Fibromyalgia
  • 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:
disturbed sleep
slight tongue swelling
metallic taste in mouth
gradual decline in speaking ability
very tender muscles
swollen inguinal nodes
unexplained missed periods
constant thirst
arrhythmia
moderate morning stiffness
frequent unexplained fevers
jaw lymph node problems
... 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
Vitamin Pantothenic Acid Need 93% Confirm
Vasomotor Rhinitis 25% Unlikely
General Toxicity 17% Unlikely
Milk Allergy 2% Ruled out
Chronic Fatigue-Fibromyalgia 2% Ruled out
Sarcoidosis 2% Ruled out
Mercury Toxicity 0% Ruled out
Indoor Allergies 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.

Sarcoidosis

Nasal symptoms and signs occur in 1-6% of sarcoidosis patients [McCaffrey TV, Donald TJ. Sarcoidosis of the nose and paranasal sinuses. Laryngoscope 1983;93: pp.1281-4], including crusting, nosebleeds (epistaxis) and bilateral obstruction.  Distinctive tiny yellow submucosal nodules can sometimes be seen.
