What is the Cause of Multiple Chemical Sensitivity (MCS)?

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:

Immune System Imbalance
Selenium Need
Multiple Chemical Sensitivity
Candida / Yeast
Vasomotor Rhinitis
Liver Congestion

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:

metallic taste in mouth

bags under eyes

major fatigue for 3-12 months

gallbladder attacks

mild diesel exhaust exposure

genital sores

occasional runny nose

inability to recover from alcoholism

current birth control pill use

high current exposure to solvents

broad-spectrum antibiotic use

having a CFS diagnosis

... 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
Candida / Yeast	90%	Confirm
Selenium Need	51%	Possible
Multiple Chemical Sensitivity	25%	Unlikely
Vasomotor Rhinitis	2%	Ruled out
Immune System Imbalance	1%	Ruled out
Liver Congestion	1%	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:

Environmental Illness / MCS

Immune System Imbalance (TH2 Dominance)

Liver Detoxification / Support Requirement

Nonallergic / Vasomotor Rhinitis

Selenium Requirement

Yeast / Candida Infection
