Being Allergic To Chemicals

What Causes Multiple Chemical Sensitivity (MCS)?

Multiple chemical sensitivity can have various causes, ranging in severity from 'troubling' to 'needs attention'.  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 multiple chemical sensitivity, 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 "multiple chemical sensitivity" as a symptom.  Here are six possibilities:
  • Candida / Yeast
  • Multiple Chemical Sensitivity
  • Selenium Need
  • Vasomotor Rhinitis
  • Liver Congestion
  • Immune System Imbalance

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:
high sugared soft drink consumption
itchy skin
being a recovering alcoholic
current birth control pill use
heart racing/palpitations
ovarian cysts
severe right lumbar pain
deformed toenails
anal itching at night
nausea for 1-3 months
history of CFS diagnosis
frequent colds/flus
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of multiple chemical sensitivity:
Cause Probability Status
Vasomotor Rhinitis 92% Confirm
Selenium Need 65% Possible
Multiple Chemical Sensitivity 25% Unlikely
Candida / Yeast 3% Ruled out
Liver Congestion 1% Ruled out
Immune System Imbalance 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.

If you indicate suffering allergic/other reactions, The Analyst™ will ask further questions including this one:
Do you suffer negative reactions to various chemicals, such as perfumes, insecticides, exhaust fumes, cleaning products, glues, paints? Symptoms might include, for example, dizziness, nausea, irritation, headache, breathing problems, fatigue.
Possible responses:
→ No / don't know
→ Minor symptoms after prolonged exposure
→ Moderate symptoms after prolonged exposure
→ Moderate symptoms after a short time, later severe
→ Severe reaction to even small amounts of chemical
Based on your response to this question, which may indicate either allergy to chemicals or severe allergy to chemicals, The Analyst™ will consider possibilities such as:
