What You Need to Know About Allergy

in Allergy

A man wants to enjoy food, yet at one bite, he develops lesions and patches of flaky and swollen tissues on his skin. A woman marvels the beauty of a flower and smells its inherent sweet scent only to be hit by asthma. Truly there is no perfect world for every man.  At some point, he is disturbed by allergy. And this puts his health in jeopardy. 


An allergy develops when our immune system over reacts with certain foreign substances that we get in contact with.  This is referred to as overreaction or exaggeration as these foreign substances are normally harmless when introduced to non-allergic people. These foreign substances are the triggering agents for allergy and they are typically called as allergens.  Allergens come in different form and shape depending on the area it attacks thereby causing allergic reactions. Some are pollens, molds and dust; some are as trivial as milk or the all time favorite of almost everyone, seafood. Others may have allergic reactions to certain types of drugs like antibiotics. One classic example of this antibiotic is penicillin.

Pathophysiology of Allergy

The exposure of the body to foreign substances known as allergens hyper-activates the immune system. As a result, the body’s immune system produces antibodies to combat those foreign substances in the belief that they are harmful organism.  This process starts the synthesis commonly known as an allergic reaction. The body’s immune system treats those substances as something hostile and is dangerous to body’s health, although they are not.  As a response, these antibodies release a kind of chemical compound known as histamine, the culprit in any allergic reactions.


Symptoms of allergy vary depending on the area susceptible to it and the substance to which the body is reacting.  Symptoms may manifest as swollen patches on the skin, watery eyes, sneezing and in some worst cases anaphylaxis or major reactions like nausea, vomiting or disturbed breathing do occur.


Treating an allergic condition for a better health is essential to get relief from its disturbing symptoms. For mild cases of allergies anti-histamine drugs that are available over the counter help. However, for severe cases of allergies strong dosage and potent anti-allergy drugs are introduced like steroid based medications.

Having this immune system disorder is not a burden too heavy to bear. There are remedies. One just needs to consult his doctor to guide him in managing an allergy health issue. However, more than anything else, simple precaution, awareness and prevention matter in order to avoid the disturbing condition of an allergy.
