Allergies: When Your Immune System Overreacts
First Encounter: Your body meets an allergen –– perhaps you inhale pollen or touch pet dander.Capturing the “Invader”: Your immune system captures the allergen and presents it to specialized cells in your lymph nodes.Creating a Memory (the IgE Antibody): If your body decides this substance is an enemy (wrongly, in the case of allergies!), it creates a specific type of antibody called IgE. This IgE antibody acts like a “wanted poster,” alerting your immune system to attack if it encounters this substance again.Mast Cells: The Alarm System: These IgE antibodies attach to mast cells (your body’s border guards). They’re stationed in your connective tissues and those barrier areas –– respiratory tract, gut, skin, and urogenital tract. Basophils, similar cells circulating in your bloodstream, also carry these IgE antibodies.Allergen Attack & Chemical Release: The next time you encounter that allergen, it binds to the IgE antibodies on those mast cells and basophils, triggering them to release histamine, tryptase, and a flurry of other chemicals. These are the troublemakers responsible for allergy symptoms –– itching, sneezing, watery eyes, hives, digestive upset, and more!
Allergy Symptoms: From Annoying to Life-Threatening
Conjunctivitis (Itchy, Watery Eyes): Inflammation of the lining of the eyes.Rhinitis (Runny Nose, Sneezing): Inflammation of the nose and sinuses.Eczema: Itchy, inflamed skin rash.Asthma: Wheezing, coughing, shortness of breath.Food Allergies: Reactions to food proteins.Anaphylaxis: This is an EMERGENCY. This severe, life-threatening allergic reaction involves multiple body systems. Symptoms include hives, facial and/or throat swelling, severe breathing difficulties, dizziness, low blood pressure, altered mental state, vomiting, loss of consciousness, and cardiac arrest.Seek immediate medical help if you suspect anaphylaxis. Epinephrine (via injectionor the recently approved nasal spray, Neffy) is the first-line treatment.
