Allergy

One may think that having an allergy to something is not a serious matter. This is actually the opposite of what is true, which is precisely why getting hold of allergy information is a must.

Simply put, an allergy is actually sensitivity to certain substances that are harmless when other people are exposed to it. But when a person who’s allergic to that substance is exposed, this would cause a reaction that can be violent in nature.

Common allergic reactions are quite minor, and these include migraine, hay fever, asthma, drowsiness, and allergic rhinitis. There are also times when the patient would suffer digestive disturbances, conjunctivitis, urticaria, recurrent sinusitis, eczema, and ear infections. The more serious cases can lead to anaphylaxis, which is characterized by the presence of histamine reaction. This particular symptom causes muscles cramps and disorientation. If anaphylaxis is not treated immediately, the patient can become unconscious in a matter of minutes. This can also lead to death by suffocation or by anaphylactic shock.

Interestingly, when a person first comes in contact with a particular allergen, the allergic reaction does not occur immediately. However, the person’s immune system becomes sensitized or aware of that particular allergen. It then mistakes the allergen for a foreign substance seeking to invade and do harm to the body. Thus, the immune system readies itself for the next instance that it would come into contact with that allergen. And when the next encounter occurs, the immune system then produces antibodies to handle the threat. But there is actually nothing to be handled by the antibodies, so they just bind with the allergen perceived, and they move along the patient’s body. As they move along, they also react with cells they come across with. To counter the perceived threat, the antibodies release histamine, which is the primary substance that can lead to anaphylaxis.

Various drugs have been developed to deal with allergic reactions. Although these drugs cannot really prevent allergic reactions from happening, they can still counter the symptoms of the allergic reactions. These drugs include antihistamines, cortisone, hydrocortisone, epinephrine, theophlene, and dexamethosone. Generally, most of these drugs can be purchased over the counter without any prescription from a physician. Still, it is better to consult a physician, rather than resort to self-medication. The symptoms one might be experiencing might be the same as that of another person. But this does not necessarily mean that both are allergic to the same substance. Thus, it is better to consult a physician to have the accurate allergy information and the cure to deal with it.
