Final answer:
An allergy is a disorder in which the immune system reacts to harmless substances in the environment, causing symptoms and manifestations. Identifying and minimizing exposure to allergens is important. Immunotherapy can help reduce sensitivities.
Step-by-step explanation:
An allergy is a disorder in which the immune system makes an inflammatory response to a harmless antigen. These allergens can be found in the environment, such as pollen, dust mites, mold, certain foods, insect stings, and medications. When exposed to these allergens, an allergic individual may experience symptoms like red eyes, an itchy rash, sneezing, a runny nose, shortness of breath, or swelling. In some cases, allergies can be life-threatening and require immediate medical attention.
To manage allergies, it is important to identify the specific allergens causing the reactions and minimize exposure to them. This may involve staying indoors during pollen season, practicing proper hygiene to reduce dust mites and mold, and avoiding known food allergens. Immunotherapy, which involves gradually exposing the immune system to increasing amounts of allergens, may also be recommended to reduce sensitivities over time.
