Allergies point to the exaggerated reaction as posed by the immune system as an answer to any physical contact with the substances that seem foreign to the body.
The response is stereotyped as exaggerated simply as the body itself deems these substances as harmless.
At the same time, those who are non-allergic have non-responsive bodies.
The reaction turns in when the body realizes that there are certain foreign substances that it gets in contact with and automatically an element of the immunity process is activated.
Allergens and their Nature The allergens are those that produce the allergy.
Some known allergens include the dust mite, pollens, foods, dander, and molds, among others.
Simply put, the allergens are those foreign substances which when it gets in contact with the body can result in the hypersensitive reaction.
Nevertheless, not all individuals exude the exaggerated reaction.
There are people who don't have the allergy on any of the previously referred to allergens.
The expression allergic also goes by the name "atopic".
It means that your immune system gets turned on as a reply to the foreign substances that gets near your body.
You develop that hypersensitive reaction when your body inappropriately responds to the allergens.
Hence, you are called allergic or atopic if you are too susceptible to the allergy.
Allergy and its Etymology The term "allergy" is rooted from the Greek words "allos" or changed or different and then "ergos" that means action or work.
The term likewise points out the "altered reaction" which the body succumbs to.
It was first employed in the year 1905 to define the detrimental reaction of the kids who received multiple shots of horse serum to fight against infection.
Determining the Causes There are lots of causes that provoke any sort of allergy to produce.
It may be as a result of dust mite, food, pets, and numerous others.
The response can be in the type of eye itching, sneezing, coughing, wheezing, skin itching, rash breakout, and the list is extensive.
As you know, your system has the immune system which fights off the foreign organisms that get into the body or those that are otherwise known as the "foreign invaders" or infections.
The antigens then provoke the generation of the antibodies and depending on the internal process, they could result to allergies.
Like the army, the immunity process aims to ruin the enemy.
The protective proteins that are known as antibodies mean to target those foreign invaders.
The antibodies or immuno-globulins protectively reach towards the surface and call every immune cell to action.
The different types of immuno-globulins are IgA, IgM, IgG, IgD, and IgE.
The latter is the one that functions as the antibody.
The Ones at Risk The rationale behind the question "Why are some individuals allergic while some are not?" can be further explained by heredity as one of the numerous aspects.
The same reaction can be passed on from one generation to another.
It is to be made clear that you might not necessarily carry the same allergy or disease like what your moms and dads have or sometimes you may not exhibit the signs.
Another factor to blame is the surroundings.
The exposure to allergen can provoke the allergic attack.
Allergies may develop despite the age.
In fact, some individuals get them while they are yet in the uterus.
Kids can carry them towards their adulthood.
A few people feel the breakout during their adult stage.
