Reported symptoms of MCS

anaphylactic shock difficulty breathing, chest pains and asthma skin irritation, contact dermatitis, and hives or other forms of skin rash migraine headaches "brain fog" (short term memory loss, cognitive dysfunction, including attention deficit) exacerbation of neurological symptoms (example: nerve pain, paralysis, weakness, restless leg syndrome, etc) extreme anxiety, panic and/or anger suppression of immune system digestive difficulties, nausea, indigestion/heartburn, vomiting, diarrhea food intolerances, which may or may not be clinically identifiable (e.g., lactose intolerance, celiac disease): commonly wheat and dairy. joint and muscle pains extreme fatigue, lethargy and lassitude vertigo/dizziness abnormally acute sense of smell (which may simply be the result of ridding one's home of strong masking scents, therefore purging olfactory neurons) sensitivity to natural plant fragrance, pine turpines insomnia dry mouth, dry eyes overactive bladder

Treatment of MCS
Biological and chemical exposure - particularly long- term - is capable of causing many systemic disturbances, especially within the functioning of the immune and central nervous systems. Such exposures are also a proposed cause of psychological illnesses like depression, though studies in this area are often inconclusive and contradictory and so physicians have as yet no guide as to the proper diagnoses or treatment of such chronic effects


  Dear Farid,

Multiple chemical sensitivity ( MCS )syndrome is a disorder that appears to be triggered by low-level exposure to multiple chemical substances commonly found in the environment. Multiple chemical sensitivity syndrome is more common among women than men. In addition, 40% of people with chronic fatigue syndrome and 16% of people with fibromyalgia have multiple chemical sensitivity syndrome as well.


  • Cause of MCS

    There are different theories as to what causes MCS (its etiology). Suggested causes include an increase in exposure to irritants or toxic injury. Several chemical- producing companies, especially producers of pesticides, have funded studies that have cast doubts on the existence and cause of MCS. Conventional medicine does not typically recognize the MCS diagnosis, because to date there is no definitive test for diagnosis or proven scientific mechanism. Symptoms may be explainable by allergic, metabolic, enzymatic, inflammatory,infectious, or psychological mechanism. Because the nature and cause(s) of MCS are still unanswered, conventional medical testing for legal purposes is not yet available


    Science recognizes that there are chemicals that build up in the body (such as mercury), but these are not yet recognized to cause allergic reactions. However, some people claim that after a meal of fish, they have an immediate bout of diarrhea. This may be another chemical sensitivity reaction. Chemicals such as mercury can also cause organ failure, such as failure of the liver (which is involved in storing these chemicals) or the kidneys (involved in filtering them out). Some chemicals are also stored in body fat. Cumulative effects on such organs should be studied in MCS patients in order to tell if there is a body burden of some chemicals or not.

  • Treatment of MCS

    Treatments offered by practitioners of environmental medicine specify the avoidance of known allergens and irritants, nutritional support to open up the body's various detoxification channels designed to purge the body of its toxic load, sauna detoxification, autolymphycyte factor treatment, allergy shots, experimental treatments and several other lifestyle changes. Enclosed, air-conditioned buildings with a recycled air supply such as shopping centres or large office buildings are generally considered particularly bad environments for the chemically-sensitive. Some with MCS find it helpful to avoid certain types of fabric for their clothing, hang printed paper outside for days to air it out (or avoid it all together), use only untreated wooden furniture, use only organic food etc. Some avoid contact with the outside world all together in favor of a controlled environment which limits exposure to offending chemicals that otherwise cannot be avoided. In our office we participate in detoxification of a lot of MCS patients from Mercury in collaboration with their physician. Since Mercury can impair immune system and can over burden one's autonomic nervous system majority of the MCS sufferers have a toxic level of Mercury in their body.
