过敏
a medical condition in which one's body severely reacts to a specific substance if it is inhaled, touched, or ingested
An allergy is a reaction by the immune system to something that is normally harmless to most people. These substances, called allergens, can trigger symptoms such as sneezing, itching, watery eyes, runny nose, and skin rash. Common allergens include pollen, dust particles, pet dander, certain foods, and insect stings. Allergic reactions can range from mild to intense, and in some cases, they can be life-threatening. Treatment for allergies may include avoiding triggers, taking medications such as antihistamines or nasal sprays, and in serious cases, receiving allergy shots. It is important to identify and manage allergies to improve the quality of life and prevent serious complications.
