The Science Behind Allergies

Friday, March 16, 2018

Perhaps you’ve wondered why a cat or spring pollen, for example, makes you sneeze and congested while others around you seem to have no trouble.  Or maybe you can enjoy a peanut butter and jelly sandwich, but your friend would break out in hives and have life threatening throat swelling if he or she tried a small piece of the same sandwich.  How can something that seems so harmless and even pleasant to some people cause such discomfort for others? 

An Allergy is an Immune System Disorder

The answer lies in the complex workings of our immune systems.  Under normal conditions, our immune system functions to protect us from harm from external threats like bacteria, viruses, and fungi; and from internal threats like cancer.  One crucial part of doing this correctly is being able to distinguish threats from things that should be harmless and beneficial like foods and our own tissues.

An allergy occurs when specific components of our immune system begin to act in an overly exuberant or aggressive way towards something that should be considered harmless and ignored.  When these usually harmless things like an oak pollen are encountered and allergic person’s immune system overacts, it can cause symptoms like hives, swelling, sneezing, itching, and in the most severe reactions death.

Allergy / Immunology is the Medical Specialty that treats allergic disorders, asthma, and primary immune system deficiencies

An Allergist or Immunologist have specialty training in diagnosing, treating, and caring for patients who have allergies, asthma, and immunologic disorders. This is obtained during two to three years of accredited study called a Fellowship in Allergy and Immunology.  Physicians who have completed medical school and a residency in Internal Medicine or Pediatrics are eligible to enter Allergy and Immunology fellowships, and those who complete these fellowships are eligible to become certified by the American Board of Allergy and Immunology (ABAI).
