A medical doctor who specializes in diagnosing and treating allergies and other immune system disorders.
From 'allergy' (Greek 'allos' + 'ergon') plus the suffix '-ist' (one who practices). The term emerged in the early 1900s as allergy became recognized as a distinct medical field.
Allergists are like detectives of misery—they use tests, elimination diets, and careful observation to figure out exactly what your body is overreacting to, then help you avoid or manage it through treatments like immunotherapy.
