Allergies
About the disease & condition
Allergies occur when the immune system overreacts to normally harmless substances called allergens. Common allergens include pollen, dust, pet dander, certain foods, and insect stings. Reactions can range from mild symptoms like sneezing and itching to severe, life-threatening conditions such as anaphylaxis. Early identification of triggers and proper management are essential to reduce discomfort and prevent complications. Treatment may include avoiding allergens, medications like antihistamines, and, in some cases, immunotherapy to reduce sensitivity over time.
