Allergies are considered American’s most common disease of the abnormal-response immune
system. They cause an overreaction to substances that are ordinarily harmless, called allergens,
which affect 2 out of 10 Americans through environmental issues. Allergies are characterized by
an overreaction to a foreign protein substance (“allergen”) that is eaten, breathed into the lungs,
injected, or touched. This can be a one-time occurrence or exposure to that allergen over a
period of time. This immune overreaction can result in symptoms such as coughing, hives, or
another skill reaction, sneezing, itchy eyes, runny nose, difficulty breathing, scratchy throat, and
asthma. An estimated 50 million Americans suffer from all types of allergies. It is not just a kid
illness anymore, with a high amount of people getting treated for allergies starting over the age
Allergies can be both indoor and outdoor. The most common allergens are ragweed, dust mites,
animal dander, mold, and grass, and tree pollen. The most common indoor/outdoor allergy
triggers are: trees, grass and weed pollen; mold spores; dust mite and cockroach allergen; and
animal dander. Insect allergies consist of bee/wasp stings and venomous ant bites; cockroach
and dust mite allergen may also cause nasal or skin allergy symptoms. Skin allergies are contact
allergies of the skin such as atopic dermatitis, eczema, and hives. Plants, such as poison ivy, oak
and sumac, are the most common skin allergy triggers. Eye allergies are allergic conjunctivitis
and ocular allergies, and are caused by outside sources.
Food allergies are milk, soy, eggs, wheat, peanuts, tree nuts, fish, and shellfish. Oftentimes,
affected people must also follow a gluten-free diet. For drug allergies, penicillin is the most
common allergy trigger. Latex allergies are allergies to latex.
With allergies you can end up with nasal congestion, a runny nose, itchy eyes, and itchy skin.
When your lungs or airways get blocked or they narrow, breathing becomes more difficult. In
turn, your asthma kicks in and you end up coughing, wheezing, and shortness of breath as you
suffer both allergic and asthmatic symptoms. There are many things you can do to eliminate the
effects of allergies. First of all a decongestant might help. When allergies make your nose
stuffed up, an antihistamine won't help. But decongestants might––and they shrink swollen blood
vessels and tissues. That relieves the congestion. Common decongestants include: Afrin, Dristan,
Vicks Sinex (oxymetazoline), Sudafed PE, Suphedrin PE (phenylephrine),Silfedrine, and
Sudafed, Suphedrin (pseudoephedrine). Antihistamines block the effects of allergies. Many
medicines combine an antihistamine and decongestant, like Allegra-D, Benadryl Allergy Plus
Sinus, Claritin-D, Xzol, and Zyrtec-D. Anticholinergic nasal sprays decrease secretions from the
glands lining the nasal passage. This diminishes the symptom of a runny nose. Examples of
steroid nasal sprays include Beconase, Dyminocort,
Qnasl, Zetonna, a Montelukast (Singulair) is a drug that relieves allergy
symptoms and is also used to prevent asthma attacks. It reduces congestion in your nose and also
cuts down on sneezing, itching, and eye allergies. For people with allergies and asthma, it helps
keep airways to your lungs open. It works by stopping the action of a chemical called
leukotriene, which causes your nasal passages to swell and make a lot of mucus. The same
chemical is also responsible for tightening airways when you have asthma, making it harder to
breathe. Singulair is a prescription medication; it is the only drug of this type that’s approved for
For extreme cases the allergist might prescribe allergy shots. Allergy shots are a form of
treatment called immunotherapy. Each allergy shot contains a tiny amount of the specific
substance or substances that trigger your allergic reactions. These are called allergens. Allergy
shots contain just enough allergens to stimulate your immune system––but not enough to cause a
full-blown allergic reaction. Over time, your doctor increases the dose of allergens in each of
your allergy shots. This helps get your body used to the allergens (desensitization). Your immune
system builds up a tolerance to the allergens, and your allergy symptoms diminish over time.
Patients undergoing allergy shots need to be careful with exercising heavily two hours before and
after the shots, and must get them each week initially, staying half an hour at the doctor’s office
to make sure that they don't have a reaction to the shots.
Another important thing is to change your environment from the causing allergens. You should
clean your bedroom from ceiling to floor, including furniture and curtains. Carpet should be
removed and dust-collecting furniture should be cleaned a minimum of at least once a week. Put
into cases mattresses and box springs in covers, and wipe mattresses weekly with a damp cloth
before you put on clean sheets. The bed clothing should be only washable blankets, and sheets
that can be washed in hot water once a week. Non-essentials should be removed from the
bedroom, including toys, books, and other knickknacks. Take out feather and down pillows or
comforters in the bedroom. The bedroom should be closed to the outside and closed when not in
use. During hot weather the air conditioner should be used with the windows closed. Vacuum
all furniture often and well. Use no scented items in the bathroom including powders,
deodorants, hair spray, and after-shave lotion. Using an air purifier in the bedroom would help
to decrease the animal dander. Keep humidity level at 40 to 50 percent. Shower after working
the garden and avoid the outside if possible if pollen counts are higher. Avoiding allergens can
help reduce the risk of allergy-induced asthma attacks. With some knowledge, allergies can be
controlled and eventually life can reoccur as it once did before. The important thing is just be
patient, no matter what treatment is pursued.

Asthma Care What is Asthma? Asthma is an allergic response within the lungs causing difficulty in breathing due to narrowing of the tiny airways. There are many triggers. About one in seven children have Asthma diagnosed at some time, and one in twenty children have Asthma requiring regular medication Recognition / Symptoms Asthma varies enormously. There are those that rarely suffer an
