Food-Dependent Exercise-Induced Anaphylaxis: A Challenging Life-threatening Condition

Abstract

Food-dependent exercise-induced anaphylaxis (FDEIA) is an uncommon but potentially life-threatening condition characterized by allergic reactions triggered by the combination of specific food ingestion and physical exertion. Despite its rarity, FDEIA poses significant diagnostic and management challenges due to its complex pathophysiology and variable clinical presentation. Diagnosis relies on careful evaluation of clinical history, symptomatology, and laboratory tests, with inherent difficulties in distinguishing FDEIA from other related conditions. Management of FDEIA involves comprehensive strategies to minimize the risk of allergic reactions through measures such as allergen avoidance, patient education, and timely administration of epinephrine. While existing treatment approaches primarily target acute reactions, ongoing research endeavors are crucial for validating emerging diagnostic and therapeutic modalities. This review offers a comprehensive overview of FDEIA, encompassing its epidemiology, underlying pathophysiology, clinical presentations, diagnostic challenges, and management approaches.
