exercise-induced anaphylaxis

noun

: an uncommon form of anaphylaxis associated with physical exertion that is characterized by anaphylactic symptoms (such as hives, itching, angioedema, or shortness of breath), that may sometimes be life-threatening, and that includes a form triggered only after ingestion of a food (such as wheat or shellfish) to which the individual is sensitized

Exercise-induced anaphylaxis is a less obvious cause of anaphylaxis … accounting for 6% to 9% of cases. Following vigorous physical activity, certain individuals may exhibit signs and symptoms of anaphylaxis comparable in severity and duration to any other cause of anaphylaxis.

—Lara Zibners et al., Pediatric Emergency Medicine Reports

Exercise-induced anaphylaxis is a disorder in which individuals develop hypersensitivity with exercise. In 30-50% of cases, the reaction is food-dependent and occurs with a combination of certain foods and exercise.
