Environmental
medicine explores the role of dietary and environmental allergens
in health and illness. Factors such as dust, moulds, chemicals,
and certain food may cause allergic reactions that can dramatically
influence diseases ranging from asthma and hay fever to headaches
and depression. Virtually any chronic physical or mental illness
may be improved by the care of a physician competent in this field.
Uses
Environmental
medicine aims to relieve disorders that its practitioners blame
on pollutants and toxins in the environment. If you are allergic
to particular elements in your diet-or to substances in the air-some
of the techniques employed by environmental practitioners could
remedy the problem. (A mainstream allergist could also help). Food
allergies, hay fever, nasal congestion, sneezing, ear infections,
and sinus headaches are all potential targets for environmental
therapies. Many environmental therapists believe, however, that
pollution's impact on health extends far beyond allergies that can
be clearly linked to a particular irritant. Indeed, they insist
that virtually all chronic maladies are caused-or at least aggravated-by
a host of natural and artificial environmental pollutants. This
proposition is considered far more dubious than the widely documented
allergies we are all familiar with. In fact, there are no scientific
studies that support it.
Procedure
of Treatment
The physicians
who target disorders of a presumably environmental nature use a
wide array of treatments, ranging from diet to a combination of
holistic, homeopathic and pharmaceutical therapy. You may encounter
some very trendy, over-the-top treatments when you visit an environmental
practitioner, but the majority fall into four categories.
Nutritional
Therapies: The use of oral and intravenous vitamins, minerals
and other important nutrients. (For more information, see the profile
on 'Orthomolecular Medicine'.)
Detoxification:
The removal of metals and chemicals from the body. (For more information,
see 'Detoxification Therapy')
Immunotherapy:
Treatments to strengthen the immune system.
Desensitization:
The process if retraining the immune system to eliminate allergies.
Before you begin therapy, the doctor will put you through a battery
of tests to help pinpoint the nature of the problem, and will take
a very comprehensive medical history. Many physicians have developed
their own treatment programmes. However, here is a brief look at
some of the more popular approaches.
Diet Modification:
Diet and nutrition are the stapes of many environmental medical
treatments. The goal is to identify various food allergies so that
the offending items can be removed from the diet. The doctor may
begin by recommending elimination of certain foods on a trial basis.
If symptoms subside in a food's absence, then return in its presence,
it is probably the source of the problem. Alternatively, the doctor
may administer a 'provocation' or neutralization' test. In this
procedure, a small amount of a suspected allergen is either injected
just beneath the skin or placed under the tongue. If the skin turns
red and forms a raised wheal at the injection site, you have a positive
response. (Don't jump to conclusions, however. False positives are
very common in skin tests for food allergies, and additional tests
may be needed.) The most common food allergies are to milk and milk
products, wheat, yeast, corn, eggs, soybeans, tomatoes, peanuts,
other nuts, citrus fruits and shellfish.
Enzyme Potentiated
Desensitization(EPD): This technique calls for administration
of extremely small doses of an allergen in order to cure your sensitivity
to it. A natural enzyme called beta glucuronidase is included to
boost desensitization. The treatments are intended to 'train' the
immune system to tolerate the allergen. They are given intravenously,
and are recommended only for those in good nutritional health. Treatments
are typically given at two-month intervals initially; then less
often as the patient begins to respond. For hay fever, one or two
treatments per year are sufficient. House dust and mite allergies
are typically treated with two doses given two or three months apart.
For stubborn disorders, results can take as long as two years to
appear. Most people must continue EPD for a lifetime, although many
are able to skip treatments for as long as five or six years before
resuming.
Chelation
Therapy: These treatments use intravenous administration of
a man-made amino acid called ethylene diaminetetraacetic acid (EDTA)
to flush heavy metals from the body. EDTA binds with molecules of
metals such as lead, iron, copper, calcium, magnesium, zinc, plutonium
and manganese, and carries them out of the system through the intestinal
tract, urinary tract, skin or saliva. It is standard treatment for
heavy metal poisoning. Many proponents also promote it as a treatment
for coronary artery disease, circulatory disorders, and stroke;
but its effectiveness for anything other than poisoning has never
been confirmed. For more information, see the profile on 'Chelation
Therapy'.
Heat Depuration:
Like chelation therapy, these treatments seek to rid the body of
chemicals such as lead, copper, iron and other toxins. Patients
are placed in a sauna heated to as high as 150 degrees Fahrenheit's,
a temperature which is thought to mobilize the chemicals from deep
stores within the body. The treatments are often administered in
conjunction with chelation therapy and other forms of detoxification.
For example, patients may spend a full day undergoing heat treatments,
exercise sessions, a massage and nutritional therapy counselling.
Each treatment lasts from 15 to 40 minutes, and 3 to 4 may be given
during the course of a day. Advocates say that an average of 20
eight-hour sessions are needed to completely clear the body of toxins.
Other Treatments:
Some environmental practitioners offer other, more controversial
types of therapy. They may prescribe DMSO (dimethyl sulfoxide),
a solvent that is sometimes used externally to relieve pain and
swelling from strains, sprains and arthritis, and that is taken
internally for certain bladder infections. You might also encounter
DHEA (dehydroepiandrosterone), a hormone that some advocates say
can reduce the risk of cancer, control immunity, regulare blood
pressure and relieve allergies. Claims for both drugs are considered
legally unproven in the mainstream medical community.
Benefits
Almost
any type of illness or disorder, from hay fever to heart disease,
can be treated with some form of environmental medicine, according
to those who practise these controversial techniques. As with most
medical treatments, however, there are no guarantees, and practitioners
say that, in general, their overall goal is to help individuals
cope with the daily hazards of their environment and, in the process,
become healthier and, in many cases, disease-free individuals. In
practice, these treatments are most commonly sought out to remedy
food allergies, mould and pollen allergies, chemical sensitivities,
and rheumatoid arthritis. Advocates say that once these disorders
are treated many other underlying diseases and illnesses, such as
migraine headaches, asthma and colitis may also improve. Other conditions
said to be relieved by environmental medicine include heart disease,
high blood pressure, chronic paediatric disorder such as recurrent
ear infections and bed wetting, premenstrual syndrome, hypoglycaemia,
irritable bowel syndrome, gastroenteritis, diarrhoea and various
abdominal pains.
Who
Should Avoid This Therapy?
Some
of the treatments offered by environmental practitioners can be
harmful under certain medical conditions. You should, for example,
avoid chelation therapy if you have kidney or liver disease. It
is also wise to avoid heat treatments if you have asthma, epilepsy,
heart disease, blood pressure problems or multiple sclerosis.
Side-effects
During
allergy testing and desensitization, there is always a chance of
an unpleasant reaction. Likewise, almost any intravenous infusion
can occasionally cause a reaction, or at least minor discomfort
and bruising at the site of the injection. Heat treatments and other
detoxification leave some people weak, dizzy, nauseous or shaky
(a result, say therapists, of the toxins mobilized into the bloodstream).
Be particularly cautious about chelation therapy. At typical dosage
levels, patients experience little more than occasional nausea,
dizziness or headache immediately following treatment. However,
in higher dosages, the EDTA used in the treatments has been known
to cause anaemia, blood clots, bone marrow damage, insulin shock,
irregular heartbeat and more.
