Introduction to Allergies

Who would find it desirable having an itchy nose, eyes, skin, or palate? The constant sneezing, wheezing,coughing, swelling, and itchiness becomes so intolerable that suddenly all our body parts rave with discomfort. It is not inviting.

There are many causes of irritation. Mostly it is triggered by pollen from trees and grasses, house dust mite, mold, pets such as cats and dogs, insects like wasps and bees, industrial and household chemicals, medicines, and food such and eggs— or to put it simply allergens.

Allergens cause allergic response. The irritations, discomforts are products of allergen intake. Allergens can be just anything to someone. And just for you to know, allergens are protein.

It is, in fact, an organic compound composed of hydrogen, oxygen, and nitrogen, which shape an important part of living organisms. However, not all allergens are limited to those with protein. The truth is, there are non-protein allergens such as penicillin and other sort of drugs. But to become allergens, these drugs turn to protein once it enters the body.

Allergic Reactions

Given already that allergens cause allergy, what does it do as why we have to experience irritation once we are exposed to these particles?

Allergens are like invaders. The immune system perceives them as so. Our system raises the red alert mode once the invaders have penetrated the body, thus in response, the body produces an anti-body to attack them leading for other cells to release further chemicals.

The chemicals being released, causes the irritation, inflammation and other symptoms of an allergic response. These reactions manifest in different ways. For instance, an individual may have problems breathing, constant coughing, sneezing, or stomach upsets.

Many allergic reactions can be experienced by the body. Anaphylaxis for example is one of them. Sudden and severe, anaphylaxis is life threatening affecting the entire body. It can be initiated by agents like food, drugs, latex, and insect stings.

Common allergic reaction is having asthma. Wheezing and difficultly in breathing best characterizes asthma. Asthma, as a chronic illness, is an inflammatory lungs disease.

Allergy can attack any part of the body. And yes, eyes are not exempted from allergic reactions. An allergy response to airborne allergens can develop in the eyes. Such allergy is referred at as conjunctivitis. Having such allergic reactions causes redness, swollen, and burning sensation in the eyes. Much worst from the eyes producing watery fluid, it causes so much pain.

More Allergic Reactions

Anything with the word having the root words "derm" would automatically refer to the skin. Allergic contact dermatitis can be caused by almost anything that comes into contact with the skin. Allergic reactions of the skin can produce rashes, hives, and atopic dermatitis, also known as eczema. Some of the known irritants of the skin include poison oak, poison ivy, nickel, latex, dyes, preservatives, cosmetics, medications, and fragrances.

Food intake may also trigger allergic reactions exhibiting indications such as loose bowel, upset stomach, vomiting, skin rashes, and breathing problems. Some food referred to as allergens are milk, egg, and even chicken. Take note however, that more allergens can take in almost any form of food apart from what has been mentioned already.

Hay fever, otherwise known as allergic rhinitis, refers to allergies involving the sinus and nose. It can be classified into two categories– seasonal and perennial. Perennial allergies are due to dust mites, molds, and pet dander while seasonal can be caused by allergens from trees grasses and weed pollens.

These are just few of the most common allergic reactions one can encounter. Although allergy is not as malignant as other diseases, it can be very uncomfortable. When the body is unable to stand the allergic reactions, allergies can send alert signals harmful to the body. The signs and symptoms of allergies can vary immensely because they depend on the type of allergy, the level of exposure, and the individual’s reaction.

Fortunately, in this day of an age, medications are easy to access. Thus relief is just a counter away. Over-the-counter medicines are available to remedy the wheezing, sneezing, runny nose, scratching and all discomforts caused by allergies to alleviate one from the cursed itchiness and irritability.
