Allergists are medical doctors who specialize in diagnosing and treating allergies and related conditions. They help patients manage reactions to allergens, which can include substances like pollen, dust mites, pet dander, and certain foods. Allergists often perform tests to identify specific allergens and develop treatment plans, which may include medications or immunotherapy. In addition to allergies, allergists also treat conditions like asthma and eczema. They work closely with patients to educate them about avoiding triggers and managing symptoms effectively. By understanding how the immune system reacts to allergens, allergists play a crucial role in improving their patients' quality of life.
