Allergic Reactions

Allergic reactions occur when the immune system mistakenly identifies a harmless substance as a threat. Common allergens include pollen, dust mites, pet dander, certain foods, insect stings, and medications. When exposed to an allergen, the immune system releases chemicals such as histamine, which can cause symptoms ranging from mild to severe. Mild symptoms may include sneezing, itching, and a runny nose, while more severe reactions can lead to swelling, hives, difficulty breathing, and anaphylaxis, a life-threatening condition that requires immediate medical attention. Managing allergies often involves avoiding known triggers, taking medications to relieve symptoms, and in some cases, undergoing immunotherapy to reduce sensitivity to allergens.
