Allergies: What's Happening in Your Body & How to Fight Back
From sneezing fits to itchy eyes — understanding allergies is the first step to living better through every season. Over 100 million Americans experience allergies annually, yet they remain widely misunderstood and often undertreated.
Every year, more than 100 million Americans experience some form of allergies, making it one of the most common chronic health conditions in the country. An allergy occurs when your immune system overreacts to a substance — called an allergen — that is normally harmless to most people. Common allergens include environmental triggers (pollen, mold, dust mites, pet dander), foods (peanuts, tree nuts, milk, eggs), insect stings, medications, and contact allergens like latex.
Prevention strategies include monitoring pollen counts, using HEPA air purifiers, managing pet dander, showering after being outdoors, reading food labels carefully, and starting antihistamines 1–2 weeks before peak allergy season.
Treatment options include antihistamines (cetirizine, loratadine), nasal corticosteroids, decongestants, immunotherapy (allergy shots or sublingual drops), and epinephrine (EpiPen) for severe anaphylaxis risk.
See a doctor if symptoms are severe or persistent, if you experience difficulty breathing or throat swelling, or if allergies are disrupting your daily life. Allergy testing via skin prick or blood tests provides a clear roadmap for treatment.
