1. ALLERGY

2. No. 1 Hypersensitivity An allergy is a reaction of your immune system to something that does not bother most other people. People who have allergies often are sensitive to more than one thing. Substances that often cause reactions are:  Pollen  Dust mites  Mold spores  Pet dander  Food  Insect stings  Medicines

3. No. 2 Anaphylaxis Allergies can cause a runny nose, sneezing, itching, rashes, swelling or asthma. Symptoms vary. Although allergies can make you feel bad, they usually won't kill you. However, a severe reaction called anaphylaxis is life-threatening. Allergic individuals can exhibit a variety of reactions depending on the allergen and the way it was absorbed into the body

4. No. 3 Types of allergy Seasonal allergic rhinitis sometimes called "hay fever" is caused by an allergy to the pollen of trees, grasses, weeds or mold spores. Depending on what you are allergic to, the section of the country and the pollination periods, seasonal allergic rhinitis may occur in the spring, summer or fall and may last until the first frost. The sufferer has spells of sneezing, itching and watery eyes, runny nose, burning palate and throat. Seasonal allergies also can trigger asthma.

5. No. 4 Allergic rhinitis Allergic rhinitis is a general term used to apply to anyone who has symptoms of nasal congestion, sneezing and a runny nose due to allergies. This may be a seasonal problem as with hay fever, or it may be a year-round problem caused by indoor allergens such as dust mite droppings, animal dander, cockroach droppings or indoor molds/mildew. Frequently, this problem is complicated by sinusitis. Patients with constant nasal symptoms should consult their allergist.

6. No. 5 Eczema or atopic dermatitis Eczema or atopic dermatitis is a non- contagious, itchy rash that often occurs on the hands, arms, legs and neck, although it can cover the entire body. This condition is frequently associated with allergies, and substances to which a person is sensitive may aggravate it.

7. No. 6 Contact dermatitis Contact dermatitis is a reaction affecting areas of the skin which become red, itchy and inflamed after contact with allergens or irritants such as plants, cosmetics, medications, metals and chemicals.

8. No. 7 Urticaria or hives Urticaria or hives are red, itchy, swollen areas of the skin that can vary in size and appear anywhere on the body. Most common are acute cases of hives, where the cause is readily identifiable as a reaction to a viral infection, medication, food or latex. Some people have chronic hives that occur almost daily for months to years, with no identifiable trigger. Angioedema is a swelling of the deeper layers of the skin. It is not red or itchy, and most often occurs in soft tissue, such as the eyelids or mouth. Hives and angioedema may appear together or separately on the body.

9. No. 8 Signs and symptoms of allergy include:  Skin reactions including hives, itching, and flushed or pale skin  Swelling of the face, eyes, lips or throat  Constriction of the airways, leading to wheezing and trouble breathing  A weak and rapid pulse  Nausea, vomiting or diarrhea  Dizziness, fainting or unconsciousness Some common anaphylaxis triggers include:  Medications (especially penicillin)  Foods such as peanuts, tree nuts, fish and shellfish  Insect stings from bees, yellow jackets, wasps, hornets and fire ants  If you've had any kind of severe allergic reaction in the past, ask your doctor if you should be prescribed an epinephrine auto-injector to carry with you.

10. No. 9 Treatment of allergy:  Immediately call your local medical emergency number.  Loosen tight clothing and cover the person with a blanket. Don't give the person anything to drink.  If there's vomiting or bleeding from the mouth, turn the person on his or her side to prevent choking.  If there are no signs of breathing, coughing or movement, begin CPR. Do uninterrupted chest presses of about two a second until paramedics arrive.  Get emergency treatment even if symptoms start to improve. After anaphylaxis, it's possible for symptoms to recur. Monitoring in a hospital setting for several hours is usually necessary.
