Allergists are medical doctors who specialize in diagnosing and treating allergies, asthma, and other immune system disorders. They help patients manage reactions to allergens such as pollen, dust mites, pet dander, and certain foods. Allergists often perform tests to identify specific allergens and develop personalized treatment plans. In addition to treating allergies, allergists may also address conditions like hay fever, eczema, and anaphylaxis. They provide education on avoiding triggers and may prescribe medications or recommend immunotherapy, which gradually desensitizes patients to allergens. Their expertise is essential for improving the quality of life for those with allergic conditions.
