An allergic reaction is the body's immune system response to a substance that it perceives as harmful, even though it's typically harmless to others. These substances, called allergens, can trigger a range of symptoms, from mild discomfort to severe, life-threatening reactions. Allergic reactions can be triggered by a wide variety of substances, including pollen, pet dander, certain foods, medications, insect stings, and latex. Symptoms of an allergic reaction can include sneezing, runny or stuffy nose, itchy or watery eyes, skin rashes or hives, swelling, difficulty breathing, chest tightness, and anaphylaxis. Anaphylaxis is a severe, potentially life-threatening allergic reaction characterized by a sudden drop in blood pressure, difficulty breathing, and loss of consciousness. It requires immediate medical attention. Allergies can develop at any age and may vary in severity from person to person. Treatment for allergic reactions often involves avoiding triggers, taking antihistamines or other medications to alleviate symptoms, and in severe cases, carrying an epinephrine auto-injector for emergency use.
