The Reasons and causes of having various Allergic Reactions

Allergies are familiar to everyone and affect about one in three at some time in their lives. There are many different sources of allergy, and symptoms range from very mild to potentially life-threatening. Allergy is one of the major factors associated with the cause of and persistence of asthma. An allergy develops when a person’s immune system over-reacts to objects — called an allergen — in the environment. These allergens are found in house dust mites, foods, drugs, insect stings, pets, pollen, latex, and molds. An allergen for one person may not be a dilemma for another person, and everyone reacts differently.

What Causes an Allergic Reaction?

Almost anything can trigger an allergic reaction.

• The body's immune system involves the white blood cells, which produce antibodies.

• This antibody type promotes the production and release of chemicals and hormones called "mediators."

• Allergic reactions are unique for each person. Reaction time to allergens can vary widely.

• Seasonal allergic rhinitis (also called hay fever) is an allergy that occurs in the spring, summer, or early fall caused by allergies to pollens from trees, grasses or weeds, or to mold spores.

• Allergies, and the tendency to have allergic reactions are hereditary -- that is, it runs in some families.

• Risk factors include certain medical conditions that can make a person more likely to have allergic    reactions:

Severe allergic reaction in the past

Asthma

Lung conditions that affect breathing, such as chronic obstructive pulmonary disease (COPD)

Nasonex Nasal Spray (Mometasone Furoate)

Nasal polyps

Frequent infections of the nasal sinuses, ears, or respiratory tract

Sensitive skin, especially sufferers of eczema

Various allergy and reactions are caused by any disorder in our immune system and a Human Body.
