How are IgE and Sport related?

The relationship between IgE and sport is complex and not fully understood. IgE (immunoglobulin E) is primarily involved in allergic responses. In some individuals, intense physical exertion can trigger exercise-induced anaphylaxis or allergic asthma, where IgE plays a role. Additionally, regular moderate exercise may modulate the immune system and potentially lower IgE levels, which could benefit allergy sufferers. However, the evidence is mostly mechanistic or based on small studies; large randomized controlled trials are lacking. There are no robust genetic markers that allow direct prediction. A DNA test for IgE and sport would therefore be speculative. Anyone experiencing exercise-induced allergies should consult a physician rather than rely on genetic tests. Overall, the link is evidence-weak and highly individual.
