Responded by an allergy to a substance the immune system that it should not react against, and the reaction is often exaggerated. Objects containing substances that cause allergies often house dust, animal hair, household chemicals, chlorine, microorganisms, pollen, nuts, citrus fruits and seafood. Also bacteria and parasites can cause inappropriately strong immune reactions.
THE OPERATION OF ALLERGY
The entire series of reactions is very complicated by an allergy. Many of these are the same as in the normal immune response, even if they occur when it should not take place. Here are some of the reactions:
By demanding a new substance, the immune cells learn to recognize that substance (allergen), and it will produce learning, to produce anti-bodies against the substance, and a certain amount of antibodies. The type of anti-IgE facilities, is the most important of allergic reactions.
IgE will glue a few mast cells in the blood and keep the surface of these cells. By following these exposures to the antigens, they will lie down on the IgE-ends to lift themselves out of the mast cells. This will trigger the mast cells that produce histamine and other signal substances. These signal substances will then spread to the surrounding tissues.
The signal substances will then trigger the walls of small blood vessels to leak fluid into the tissue and accumulate in the tissues. This causes soft tissue swelling. They will also cause blood vessels to expand and thereby increase the flow of blood into the tissue. The result will be swelling and redness of the affected parts. The signal will also produce substances in the mucus gland tissue, which symptoms such as runny nose, narrow neck.
The new demands on the antigens will also provoke nor antibody production. The antibodies will also glue allergens together to larger complexes. These complexes can disrupt small blood vessels and other means to block the function of the affected organ.
The allergen-antibody complexes are then approved by the cells and other mechanisms that the body uses to collect and remove rubbish recognized. Eater collect cells and engulf the complexes.
The immune system will break even enzymes that attack the antigens on them. Also this production is stimulated when antigens attach to anti-bodies at cell surfaces. But these enzymes are not entirely specific and can also extend to some components of the breaking of the body’s own tissues, causing damage and disease symptoms.
What causes the immune system with allergy REACT TO A SUBSTANCE
At the beginning of the life of a person who has the effectiveness of the immune system to react against most substances in the body itself and the surrounding area. However, there are mechanisms that learn to recognize the immune system infanthood to normal substances found in the daily life in the early, and to suppress the reactions to them. If this learning mechanism is disturbed, can develop allergies.
Allergy can also develop if a child is never exposed to a substance that later a normal part of his daily life are revealed. In this case, the immune system is not given the chance to suppress the reaction against this substance. Rent a young child growing up in a pronounced clean and sterile environment can therefore cause allergies.
On the other hand, certain elements can not be part of a normal environment cause allergies by repeated and massive exposure. Examples of such substances are chlorine.
Types of allergies
Allergy depends on the compound that causes the immunological reaction. An allergic condition also often implies reaction to a combination of several substances. Common allergy-causing substances are: pollen, house dust mites in house dust, mold and mold spores, chlorine, chemicals in soaps and cosmetics, animal hair, seafood, strawberries, fish, parasites, drugs such as antibiotics and anesthetics
An allergic condition may periodically be better or worse after the concentration of allergens in the environment. A typical example is pollen allergy with peaks in the pollination season of grass or Treas.
An allergic person will often receive complaints from multiple tissues in the body, but the symptoms are often prominent at one body part and the very specific symptoms at the site. Examples of specific conditions were often caused by an allergy, the skin is eczema and asthma in the lungs and lower Airpipe.
The symptoms of allergy
Each institution may show allergic reactions, but often the symptoms are limited mainly to one organ or organ system.
Of allergic reactions in the airways will be symptoms like: Itching and pain in the throat and nose cavities, swelling of the airway tissues, increased amount of secrets in the respiratory cavities and coughing. It can also asthmatic symptoms or fully developed asthma. The main symptom of asthma is cramping that narrows the airways to the lungs (constriction of the trachea and tracholes).
Of allergic reactions in the skin it will cause symptoms such as: redness, swelling, red spots, itching and rising.
How to Prevent ALLERGY
In order to prevent allergies in an individual case, the best way possible, one should begin in early childhood.
A child must have the opportunity to keep in contact with natural elements such as soil, getting dirty, animals, plants, physical contact with other people, and the like. This made exposure to natural elements must occur before an allergy has developed. In this way the immune system will learn to identify common elements and harmless, and not against them later in life overreact.
Research projects have found that children with a lot and early contact with pets such as cats and dogs a chance later to fewer allergies than children not in contact with pets have. This is contrary to what many people believe.
On the other hand, each person should not be protected from early childhood from certain elements, usually in a natural environment, for example chlorine, soaps and cosmetics with artificial substances and foods with unnatural additives.
METHODS FOR THE TREATMENT OF ALLERGY
The first approach in the treatment of manifest allergy is the avoidance of exposure to substances causing the allergic reactions. Even if the exposure to natural substances can prevent allergy, exposure to an allergen should be avoided if has already developed an allergy. Ways to do this is to:
- Avoiding food, defends itself against the one
- Avoid contact with animals to have experienced an allergic reaction to
- Keeping rooms, beds and furniture well cleaned clothes
- Avoidance of the use of detergents, soaps and cosmetics with unnatural additives
- Avoidance of foods, drinks and snacks with unnatural additives
- Avoid daily exposure to chlorine and other chemicals
- In cooperation with your doctor to change medications that you can use that cause allergies to other
- Prevention of growth of molds in the environment. This is by cleaning and protecting the environment dry.
Children are often exposed to allergens at school, and adults are often exposed at work. Parents with allergic children must investigate the school environment and to demand from the school principal and teachers is practicable, that environmental measures are provided to the school always free from allergens. An employee should request the same from his employer.
If you do not exactly everything you react against not know, you can try to stop the exposure to one factor after another, until you feel that the allergy reduced, then this factor is always of your daily life for the future.
Sometimes avoiding allergens is difficult to fully achieve, or take his restricted lifestyle acceptable. Then you have to for medical treatment, which reduces the allergy.
A common method for the treatment of allergies is the use of drugs that block the action of the substance histamine and thus ameliorate or prevent the symptoms, if the antigen is absorbed into the body.
Another possibility is desensitization. Through this treatment, an order that the body a controlled and gradual increase in exposure to the allergen over a given period of time, and if that time is up, they let the body get recurrent exposure to a controlled dose at regular intervals. This treatment gradually decrease the response of the immune system by allergens, because the immune system thereby learns to recognize the allergens as harmless, and partly because the antibodies against the allergens are exhausted.
There are also natural products on the marked that contain ingredients that the immune system to help respond appropriately. Important effects of these products are reduced histamine secretion and increased histamine metabolism. Examples of these medicines are components:
Methylsulfonyl methane, vitamin C, vitamin E, Echinacea purpurea, quercetin, grape seed, nettle, Coleus Forskolin.
Asthma & Allergy Cure -drug Free.
