Allergy Check
By Justin Flowers
An allergy occurs, when a person becomes sensitized to a known substance, that starts an allergic reaction. These substances are called allergens, or triggers, because they trigger an overreaction in the body’s immune system. There are naturally occurring allergens, like pollens, environmental substances, like chemicals, and the foods that we consume, mostly proteins, amongst numerous others.
There are four main ways through which allergens can enter the body:
Inhalation - as with dust mites and pollen.
Eating - as with some foods.
Absorption - through the skin, as with some chemicals and plants.
Injection - some people are allergic to drugs, such as penicillin.
If an allergic individual encounters an allergen, for the first time, the symptoms do not occur, but the immune system becomes sensitized. Think of it, as being ready to resist allergens, that it wrongly considers to be invaders, intent on doing harm to the body.
Having become hypersensitized to a specific substance, when the immune system encounters a similar allergen; it automatically mass-produces antibodies to deal with the imagined threat. The antibodies bind with the allergens, and as they move throughout the body, they react with other cells. Then substances, including histamine, cause inflammation, that is a common allergy symptom. differ in many people, and the symptoms range from something as mild as a drippy nose, to anaphylactic shock, which can be fatal.
Testing and Diagnoses
Where it is suitable, skin testing is preferable to blood testing, because it is more specific, easier to do, and costs less. Nevertheless, your physician will advise what is best suited to your disorder.
Treatment
Doctors, who are specialists in dealing with allergic diseases, undergo extensive training. In the United States a minimum of nine years is required to qualify as an allergist immunologist. It is reassuring to know that real advances in medical treatments have been developed by allergists. These include quick acting epinephrine tablets, low allergy foods, and advances in dealing with yellow jacket stings.
Immunotherapy
If immunotherapy is considered a suitable treatment, it may either limit the intensity of an allergy or cure it completely. It involves injecting progressively increased doses, of the allergen, iknown to be causing the symptoms. There have been good results in dealing with rhinitis and asthma.
Medicinal Drugs
Several drugs are available to counter the symptoms of allergy which include, antihistamines,
cortisone, hydrocortisone, theophlene, epinephrine, and dexamethosone. A few preparations are obtainable over the counter, but it is best to seek advice from your doctor, what is recommeded for your own allergy.
General
It is not known precisely why some people suffer from allergies, whilst others do not. It may be that there is an inherited reason for some allergies.
It does seem sure that the incidence of is on the increase, and that it may have something to do with contemporary living.
For instance, offices have become airtight, with windows that used to open being replaced by air conditioning. That being said the quality of the outside air, particularly in built up areas, is questionable. On a world wide basis, rain forests are diminishing, whilst pollution emitting vehicles are increasing. Add the development of the emerging nations, and you have a recipe for industrial soup.
Some of the Chinese settlers develop hay fever, after moving to the United States, for a few years. More recently, there has been much publicity about industrial pollution in Beijing, and other places. It seems that the time could soon arrive, when the good people of China will have their own, local grown variety of rhinitis! Will the new found success be accompanied by allergic respiratory disorders – if it does, it must prove something!
