HAY FEVER, ALLERGY AND ASTHMA
Hay fever is a chronic condition characterized by sneezing, nasal
congestion, runny and itching nose, palate, ears and eyes. If you
recognize any of these symptoms chances are, you or some member of
your family has experienced hay fever at one time or another.
Doctors call it allergic rhinitis. Most people know it as hay fever
and if you've got it - - as 22 million Americans do - - you're likely
to be plagued during the spring and fall seasons by such annoying symptoms
as sneezing, congestion, runny nose, itchy throat and red, watery eyes.
Allergy has different names. Allergy reactions occurring in the nose
and sinus are called "sinus" or "hay fever" or "allergic rhinitis."
And when allergy reactions occur in the chest we call it "asthma."
Allergy reactions in the skin are named "hives" or "angioedema." So
you see, allergy has different names depending upon where in your body
it occurs.
One out of every six Americans suffers from an allergic condition.
Allergy is an inherited trait, a genetic susceptibility towards the
production of certain allergy anti-bodies. Hay fever is basically
an allergic reaction to pollens from trees, weed and grasses. Unlike
garden flower pollen, which is carried by insects, the dry lightweight
pollens which cause allergic rhinitis are generally spread by wind
currents which make them difficult to avoid. In fact, samples of ragweed
pollen have been found 400 miles at sea! While most people suffer
mild discomfort with hay fever, it is estimated that more than 40 percent
of the 5.8 million children who have respiratory allergies miss some
school, stay in bed or feel upset by the condition.
Additionally, complications from allergic rhinitis can be serious.
The same allergens that cause hay fever can reach the lungs causing
asthma and other complications. Sinusitis (inflammation of the sinus
cavities) and nasal polyps (small outgrowths of the mucous membrane
of the nose) may develop. Secondary infections of the ear, larynx
and bronchial tubes may occur. Also, prolonged year-round nasal stuffiness
and mouth breathing may lead to facial bone growth changes in children.
Surprisingly, many parents realize that their children have asthma
before their physicians do. An accurate diagnosis, however, is most
important in helping to determine an appropriate individualized treatment
program. Physicians specializing in allergy/immunology have special
skills in the area of asthma management. The allergy and asthma specialist
will detect and determine those environmental elements (pollens, molds,
dust mites, animal danders, workplace chemicals) which may be the cause
of a patient's asthmatic condition. A careful medical history, physical
examination, selective allergy skill testing and lung function studies
are typically performed. Occasionally, blood tests, home and workplace
evaluations, and x-rays of the sinuses and lungs are required.
Unlike hay fever, asthma is a more complex disease involving a reversible
constriction of the muscles lining the human airways,. It is more
often associated with allergy immune cells and can get progressively
worse reaching life-threatening stages if not properly controlled.
It can be treated more effectively when it is diagnosed early.
The best therapy of all, however, is avoidance of those things which
produce asthma symptoms. This includes allergens, such as house dust
mites, pets and irritants, such as tobacco smoke and chemical fumes.
