Practical Measures to Prevent and Treat Allergy Published: 25.06.2008 | Author: Aquila | Category: Disease & Illness
By allergy the immune system react against a substance that it is not supposed to react against Jay Bruce Mets Jersey , and the reaction is often exaggerated. Objects containing substances that commonly cause allergy are domestic dust, animal hair, household chemicals, chlorine, microorganisms, pollen, nuts, citrus fruits and seafood. Also bacteria and parasites can cause inappropriately strong immune reactions.

THE MECHANISMS OF ALLERGY

The total set of reactions occurring by allergy is very complicated. Many of these are the same as by normal immune reaction, even though they occur when they should not take place. Here are listed some of these reactions:

By exposure to a new substance, cells in the immune system learn to recognize that substance (allergen), and it learns to produce anti-bodies towards the substance, and a certain amount of antibodies is produced. The type of anti-bodies called IgE is the most important by allergic reactions.

IgE will glue itself to some cells in the blood called mast-cells, and stick out from the surface of these cells. By following exposures to antigens, these will attach themselves to the IgE-ends sticking out from the mast-cells. This will trigger the mast-cells to produce histamine and other signal substances. These signal substances will then spread through the surrounding tissues.

The signal substances will then trigger the walls of small blood vessels to leak fluid into the tissues and accumulate in the tissues. This will cause tissue swelling. They also will cause blood vessels to widen and thus increase the blood stream in the tissues. The consequence of this will be swelling and redness in the affected body parts. The signal substances will also make glands in the tissue produce more mucus, making symptoms like running nose and tight throat.

The new exposures to the antigens will also provoke even more anti-body production. The antibodies will also glue allergens together to bigger complexes. These complexes can clog small blood vessels and in other ways disturb the function of the affected organ.

The allergen-antibody-complexes are then recognized by the cells and other mechanisms that the body uses to collect and eliminate garbage. Eater-cells gather and engulf the complexes.

The immune system also will make enzymes that attack the antigens to break them down. Also this production is stimulated when antigens attach themselves to anti-bodies at cell surfaces. But these enzymes are not entirely specific, and can also to some extend break down components of the body鈥檚 own tissue, causing harm and disease symptoms.

WHAT CAUSES THE IMMUNE SYSTEM TO REACT WITH ALLERGY TO A SUBSTANCE

In the beginning of the life of a person, the immune system has the potency to react against most substances in the body itself and the surroundings. However, there are mechanisms that learn the immune system to recognize normal substances found in the daily life in the early infanthood, and suppress the reactions against these. If this learning mechanism is disturbed, allergy can develop.

Allergy can also develop if a small child is never exposed to substances that later will be a normal ingredient of his daily life. In this case the immune system will not get the chance to suppress the reaction against this substance. Letting a small child grow up in an exaggerated clean and sterile environment can therefore cause allergies.

On the other hand, certain elements not being a part of a normal environment can cause allergies by repeated and massive exposure. Examples of such substances are chlorine.

TYPES OF ALLERGIES

Allergy varies according to the compound that causes the immunological reaction. An allergic condition also often implies reaction against a combination of several substances. Common substances causing allergy are: Pollen, domestic dust, mites in domestic dust, moulds and mould spores, chlorine, chemicals in soaps and cosmetics, animal hair, seafood, strawberry, fish, parasites, medicines like anaesthetics and antibiotics

An allergic condition may periodically get better or worse according to the concentration of the allergen in the environment. A typical example is pollen allergy with peaks in the pollination season of grass or treas.

An allergic person will often get symptoms from several tissues in the body, but the symptoms are often most prominent at one body part and give very specific symptoms at that site. Examples of specific conditions often caused by allergy are eczema in the skin and asthma in the lungs and lower airpipe.

THE SYMPTOMS OF ALLERGY

Any organ can exhibit allergic reactions, but often the symptoms are confined mainly to one organ or organ system.

By allergic reactions in the respiratory system there will be symptoms like: Itching and soreness in the throat and nose cavities, swelling of the airway tissues, increased amount of secrets in the airway cavities and coughing. There may also be asthmatic symptoms or fully developed asthma. The main symptom of asthma is cramping that constricts the airways all the way down into the lungs (constriction of the trachea and tracholes).

By allergic reactions in the skin, there will be symptoms like: Redness, swelling, red spots, itching and soars.

HOW TO PREVENT ALLERGY

To prevent allergies in an individual the best way, one must begin in early childhood.

A child must be allowed to get in contact with natural elements like earth, dirt, animals, plants, physical contact with other humans, and the like. This exposure to natural elements must occur before an allergy has developed. In this way the immune system will learn to recognize common and harmless elements, aning nosy to intervene i.
