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. |
