Living in Southeast Texas, it is not uncommon to have what is commonly known
as the "sniffles," also popularly known as "hay fever". With conservative
estimates, 60% of the Southeast Texas population has the ailment, which
means that chances are someone very close to you will have it. And, if they
are lucky enough not to have it, then guess what, you have it.
Allergic Rhinitis is characterized by sneezing, runny nose, itching of the
nose, nasal blockage, excessive tears and headache. It also commonly
includes a loss of smell. The allergic reaction in hay fever occurs in the
lining of the upper respiratory tract which includes the sinuses, nose and
bronchial tubes. Allergens, ranging from pollens, spores and petrochemical
products, when breathed into the respiratory tract, get picked up by the
cells lining the upper respiratory tract. The body then elicits a response
by special cells called Mast Cells which produce hormones, which in turn are
responsible for the sneezing, runny nose, itching of the nose, nasal
blockage, etc..
At any given time, up to 20% of the population of United States has an
active "case" of allergic rhinitis. Certain localities like Southeast Texas
has a much higher occurrence rate. The higher incidence in our area is due
to pollens and the presence of so many petrochemical products in the air.
Arbitrarily, rhinitis lasting less than six weeks is called acute rhinitis,
and persistent symptoms are called chronic rhinitis. Acute rhinitis is
usually caused by infections or chemical irritation. Chronic rhinitis may be
caused by allergy or a variety of other factors. There are roughly two
Types of allergic Rhinitis:
- Seasonal which occur at certain times of the year.
- Perennial which occur all year long.
Pollen is the biggest factor in the seasonal variety. There are different
pollens. Ragweed Pollen, most common in the Mid-western states, usually
acts up between mid August to early October. Tree Pollen, elicits symptoms
in early Spring. Grass Pollen affect us in late October to early summer and
is probably the biggest offender in Texas. Some Mold spores also play their
part in the grand scheme of things from July to early August. People that
have symptoms only in certain seasons have the above mentioned players to
thank for.
People who have symptoms from time to time all year round are probably
reacting to things like house dust, dead skin cells from pets, indoor molds
and occupational allergens coming from factories and refineries. Other
things that play an important part in provoking the symptoms of allergic
rhinitis are perfumes, cooking odors and, quoting one of my patients, "
spouses." The last allergen is a joke! If you start sneezing when your
wife walks in, it's not her; trust me. Check her perfume or powder.
Allergic Rhinitis is a frustrating problem to take care of, but there are
excellent ways of treating it. First and foremost identifying a specific or
a couple of offending agents greatly helps in avoiding those substances.
Avoidance is key in fighting this menace. The following precautions will
lessen exposure to air-borne allergens like pollens:
- Close windows, use air-conditioning to clean, dry the air.
- Use a HEPA filter system to remove airborne allergens.
- Stay inside when there is a high pollen count, humidity or wind.
Many weather stations now give the "pollen report" which will help you avoid
high pollen days.
- Realize that outside pollen and mold are highest midmorning to late
afternoon.
- If exposed to pollen, shower, shampoo hair, rinse eyes with saline.
- Keep pets out of main living areas, especially bedrooms.
There are now certain skin tests that can be done without any risks that can
identify the causative allergic agent. Diagnostic measures include a
careful clinical history and physical along with allergen skin tests. But,
remember, positive skin tests are only important if they correlate with the
clinical history. A RAST (RadioAllergoSorbent Test) may be done if
traditional skin tests cannot be performed.
If avoidance is not possible or is just not enough, certain medicines like
nasal steroids are available that are the treatment of choice. These
medicines work by preventing the Mast Cells from secreting their hormones
thus preventing the immune response which is responsible for the symptoms.
The problem I see everyday is that people use these medicines on an "as
needed" basis. Unfortunately, that's not the way these medicines work.
These medicines are supposed to be taken daily just like diabetes or high
blood pressure medicines. They are more effective in keeping the ailment
away rather then healing it once it starts. There are other drugs available
that supplement nasal steroids. Drugs like Claritin and Allegra are now
household names in Southeast Texas. This should just give us an idea of how
rampant this ailment is.
Some known complications of allergic rhinitis include ear infections,
sinusitis, recurrent sore throats, cough, headache, altered sleep patterns,
fatigue, irritability, and poor school performance. Occasionally, children
may develop altered facial growth and orthodontic problems. Allergy
treatment can eliminate or alleviate most of these problems.
The best way to treat allergic rhinitis is to let your healthcare provider
know at earliest onset of symptoms because we all know, "Prevention is
better than cure". Remember, its Your Life and Your Health.
