Avoiding allergic reaction

Oct 8th 2013 at 11:55 PM

When most individuals use the term allergic reaction, they are referring to reactions involving class antibody immunoglobulin E
Antibodies bind to special cells, including basophiles present in blood and mast cells present in tissues. When antibodies are attached to these cells are antigens, called allergens this case, cells are stimulated to release chemicals that damage the surrounding tissue.
An allergen can be anything (a speck of dust, pollen of a plant, a drug or a food) that acts as an antigen to stimulate an immune response.

Sometimes atopic disease is the term used to describe a group of diseases mediated by and often hereditary, such as allergic rhinitis and allergic asthma.
The atopic diseases are characterized by their tendency to produce their antibodies against inhalant harmless (e.g., pollen, mold, animal dander and dust mites).
Eczema (atopic dermatitis) is also an atopic disease, although the role antibodies disturb this is less claret.

Canted an individual with chronic atopic does not present a greater risk to produce antibodies against allergens injected (e.g., drug or insect venoms).
It's allergic reactions ranging from mild to severe. Most reactions consist only of the hassle of tearing and itchy eyes and some sneezing.

At the other extreme, allergic reactions can be deadly when they involve a sudden difficulty breathing, cardiac dysfunction or severe hypotension leading to shock. This type of reaction, called anaphylaxis, can occur in sensitive people in different situations, how soon after eating certain foods after the use of certain medicines, or after a bee sting.
