Which are the causes of Multiple Chemical Sensitivity?

I understand there can be many underlying causes to MCS. I believe mine is tied to fibromyalgia and overexposure to chemicals at a particular time in my life.

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

Genetics combined with toxic chemical exposures cause MCS

I wish I knew!

In my case most. petrochemical derivates.

I have been dealing with this for 24 years and 71 now I have found if I can live in avoidance to these chemicals, I feel perfectly normal and I function my problem is not finding a place that I can afford a separate unit. I have been in section 8 apartments and moving like a gypsy since I had to sell my home which was where I first got sick constantly moving because of chemicals that come in from the neighbors kitty litter, which is unbelievable what it’s done to my body as well as my dog people don’t realize how bad that stuff is in the cigarette smoke, and then later exposed to mold, but I do believe we could live much longer if we had healthy places to live where I’m at fresh clean air to breathe is a rare commodity. I’ve been here for 18 months and looking for another place. If I don’t find one suit I think this place is going to do me. I think, as long as you could live in avoidance and stay in avoidance to the chemicals, you could live a long life. I have also found when you tried to explain to neighbors what you go through what you have you would think that they would be more understanding however they are not each time I have found they’ve become offended by it. They do not care what you’re going through they don’t feel it so they can’t understand it’s affecting them as well. I won’t try to explain if we get sick if they see us it just starts trouble what might’ve been a good neighbor and a good friend has now got it

Where I lived prior to this, I learned something that I was surprised that I had been two different units there near people that were hoarders. One kept 16 dead cats along with just many life ones after moving to another unit I was exposed to so much mold, and the landlord would do nothing about it.

While we were there, I found because of the stock piled trash with dirty kitty litter in her sunroom, which would come into my sunroom and it would go I guess up into the ceiling that smells heat rises and it would come into my unit and it would make me so sick I would go into tremors. I’d look like I was having a seizure. I had to go outside and sit and then cold air at winter just so they could breathe. It would take an hour for it to get out of my body, but my dog started having problems with it too before I move from there I had to get his anal gland strained, and at the same time I started having problems every time I would say it felt like somebody had sticks poking up inside of me on either side of my butt. Then I started to get these water blisters on each side on the outside only to find out that was my anal glands too, and it was being caused by the chemicals in the kitty litter, and I also recall an ant of mine who had a cat, and when you walked in, you can smell this pretty scent of the kitty litter. She was having the same problem years ago. Nobody knew why it was just like nobody knew why dogs had to get their anal glands drained every now and then but I found that was probably from the dogs that were kept inside the house not the ones that were outside.

Kitty litter had also caused me to have a deviated septum. My nose would swell three times the size when I was being affected by it. My head hurts so bad my ears I couldn’t breathe then I started having problems with my chest. I went to a pulmonologist and x-ray showed, I now have cysts and nodules on my chest wall and lung so I’m on oxygen.

I started researching and found out there are horrible toxic chemicals in kitty litter. The scented ones the scent is horrible. It’s all chemical but if you get the ones that say unscented, they still have odor eliminator and those odor eliminatorsare horrendous what they do to your body

I’ve also found everything that we bring into our homes sits in a warehouse waiting for us to purchase. It’s full of chemicals so it doesn’t get mold or mildew to bottle the dampness. We bring that home even a baby blanket, clothing appliances, and people don’t even know their elf guessing TV

Your refrigerator can off gas gas for up to 10 years. And the government seems to allow this. I guess it’s about the Almighty dollar not about people.
Wouldn’t you try to educate people? They look at you like you’re crazy. They have no clue what’s happening to them because they’re not feeling it. Because of what I’ve been through and at first, I tried to explain a little bit about what I go through. I get mocked and harassed where I met now and they do things purposely wax melts, burning candles, smoking cigarettes up by the building constant and I am on the way for a waiting list for another apartment to move to because I can’t afford anything else because when I first got sick, no matter how hard I tried to keep going to work I couldn’t do it and I was surely not ready for retirement and Social Security disability.
But I’m still alive still battling, although it gets harder every day. I don’t know that there is a life expectancy time for us. I think it all has to do with where you’re living how you’re taking care of yourself and that you must live in avoidance.
