Which are the causes of Multiple Chemical Sensitivity?

See some of the causes of Multiple Chemical Sensitivity according to people who have experience in Multiple Chemical Sensitivity

There are three ways someone becomes chemically sensitive:
1. Massive Exposure (pesticide application, mold infestation, etc)
2. Life-changing event (major surgery, childbirth, etc...something that changes the body chemistry)
3. Low level of exposure over a long period of time (most typical way... our bodies just cannot accept more pollutants)

The main causes of MCS would be DNA and exposure to toxins/chemicals.

Environmental toxins, impaired immune system, methylation errors, glutathione deficiency.

Exposure to tons of harmful chemicals at one time or to small amount of chemicals for a long time.

The most common cause is an intense exposure to a chemical knowingly or possibly not known at the time.

Again, a difficult question. Many things can trigger it. It can be many small exposures or one big one. I actually think that everyone is affected but some of us are more sensitive so we can avoid the toxins. I know that I have suffered all my life but didn't know what it was until recently. I was diagnosed with facial neuralgia around seven years old and have never been able to drink very cold or hot liquids. I had a difficult birth resulting in being stuck for 72 hours in my mother's vagina. Nine weeks later the UK had the worst pollution ever recorded to date with the London smog. I helped my uncle on the farm from the age of seven with things like dipping the sheep! We always ate food we grew so that was good.

Harsh chemicals. They are poisoning everything and making us all sick, including the planet.

The causes of multiple chemical sensitivity are unknown. It can be triggered by a number of things including reactions to chemicals, exposure to toxins or environmental irritants, or illness. More research needs to be done to determine if there is a genetic basis to MCS.

Immunological reactions to your environment, if there are no tests to diagnose the condition, you won’t have known when your first symptom was as you would not have necessarily have recognised it as anything to do with MCS, as your condition progressed then you could recognise and make a connection between your symptoms and your triggers.

A build up of toxins and an inabliity to process what you use to be able to. This is still being researched, but as evidenced by knowing what makes you ill, there is the clue.

Chronic or acute toxic chemical exposure...sometimes EMF exposure can also start the process or worsen things.

Other immune deficiencies can cause MCS, but I personally was diagnosed due to an overexposure over time.

There is not much known of MCS and what causes it. There are various types of MCS (fragrance sensitive, food allergy, enviromental impact).

I feel that anyone can get MCS. Once our body hits its toxic overload - we have MCS. That can be caused by many many things and combinations. For example - years of chlorine exposure and then getting new carpet and bam! You’ve got MCS.

It all depends of a persons ability to clean out the toxins from their body - how healthy their liver is -and how exposed daily that they are. Sometimes just a neighbor spraying fungicide is enough to put you over the tipping point. Everyone’s story of how they got MCS is unique.

Over exposure, during pregnancy of the mother, or over exposure by conditions (places) in life.

Brain injury
Chemical injury
Genetic predisposition
Co-occurring autoimmune illness or cancer
Neurological condition
Long-sustained physical or psychological trauma

They aren't 100% sure.
They know mold, some genetics, lyme disease, exposure to chemicals over a prolonged period or a 1 time serious chemical exposure can cause mcs

MCS is believe to be caused from a genetic defect. It may be inherited. My sister also has fibromyalgia but does not have the chemicals.

Usually a toxic overload

Posted Jul 24, 2021 by Serenity 2500

Genetics combined with toxic chemical exposures cause MCS

I wish I knew!

In my case most. petrochemical derivates.
