When a person with an allergy is first exposed to an allergen, their immune system produces specific antibodies of the IgE class (immunoglobulin E). These antibodies attach themselves to , which are found throughout the body’s tissues, particularly in the skin, nose, and lungs.
The Invisible Defense: Understanding Allergies An allergy is a chronic condition characterized by an exaggerated immune response to substances that are typically harmless to most people, such as pollen, pet dander, or certain foods. While the immune system is designed to protect the body from dangerous pathogens like bacteria and viruses, in an allergic individual, it mistakenly identifies these neutral substances—known as —as threats. This "mistaken identity" triggers a biological chain reaction that can range from minor discomfort to life-threatening emergencies. The Mechanics of an Allergic Reaction allergy

Upon subsequent exposure, the allergen binds to these IgE antibodies, signaling the mast cells to release histamine and other inflammatory chemicals into the bloodstream. Histamine is responsible for the classic symptoms of an allergy: While the immune system is designed to protect
