Some people experience severe allergic reactions triggered by physical activity, including exercise-induced anaphylaxis. Multiple reports note that exercise is a relatively uncommon cause of anaphylaxis, with global estimates suggesting roughly 2.3% to 5% of anaphylaxis cases are triggered by exercise. The condition can be serious, and the symptoms overlap with those seen in other anaphylactic or allergic reactions. Reported features can include sudden onset of reactions during or shortly after exercise, with involvement of multiple body systems such as the skin, breathing, and cardiovascular system. Because the presentation can resemble other allergic reactions, diagnosis and awareness of warning signs are important for people who develop symptoms with exertion. The available sources emphasize that exercise-triggered anaphylaxis is real, potentially life-threatening, and not limited to any single type of allergy, but it affects a minority of anaphylaxis cases overall.
