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.

  • see your health summarized and in detail
  • have a doctor review your case (optional)
  • 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 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:
  • Vitamin Pantothenic Acid Need
  • Milk Allergy
  • Chronic Fatigue-Fibromyalgia
  • General Toxicity
  • Vasomotor Rhinitis
  • Sarcoidosis
  • Indoor Allergies
  • Mercury Toxicity

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:
much reduced sense of smell
afternoon headaches
occasional confusion/disorientation
being an unsocial person
bloodshot eyes
moderate mercury toxicity
frequent sneezing / attacks
frequent painful inguinal nodes
occasional 'chills'
much past amalgam filling removal
occasionally feeling unusually cold
diminished perspiration
... 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
Chronic Fatigue-Fibromyalgia 94% Confirm
Indoor Allergies 24% Unlikely
Vasomotor Rhinitis 18% Unlikely
Sarcoidosis 0% Ruled out
General Toxicity 0% Ruled out
Mercury Toxicity 0% Ruled out
Vitamin Pantothenic Acid Need 0% Ruled out
Milk Allergy 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.
