Browsing: Allergy

An allergy is an immune system response to a substance that is typically harmless to most people, known as an allergen. Common allergens include pollen, pet dander, certain foods, insect stings, and medications. When a person with an allergy is exposed to an allergen, their immune system mistakenly identifies it as a threat and releases chemicals such as histamines, leading to symptoms that can range from mild to severe. These symptoms may include sneezing, itching, rashes, swelling, difficulty breathing, and in extreme cases, anaphylaxis, a life-threatening reaction. Allergies can significantly impact quality of life and require management strategies such as avoiding known allergens, taking medications like antihistamines, and in some cases, undergoing immunotherapy to reduce sensitivity. Understanding and managing allergies is crucial for reducing their impact on health and well-being.
