While an active lifestyle with sports activities is often recommended for good health, it can pose a lesser-known but serious risk for some individuals. Food Dependent Exercise Induced Anaphylaxis (FDEIA) is a condition where physical exercise triggers an allergic reaction to certain foods consumed before the activity.
In a recent case study at Sir Ganga Ram Hospital, a 12-year-old boy, who was otherwise healthy, experienced severe itching, swelling, and breathing difficulty just 10 minutes into a cricket match after eating shrimp salad for lunch. Dr. Neeraj Gupta, an Allergist, Pediatric Intensivist, Sleep Specialist, and Senior Consultant at the hospital, explained that the boy was rushed to a nearby hospital where doctors identified the signs of anaphylaxis. Allergy testing revealed that the combination of shrimp consumption and exercise triggered his condition, a classic case of FDEIA.
Gupta elaborated that FDEIA occurs when physical exercise triggers an allergic reaction to specific foods consumed prior to the activity. Unlike typical food allergies, which are triggered immediately after ingestion, FDEIA requires both the consumption of allergenic food and subsequent exercise to provoke symptoms.
Symptoms of FDEIA can vary but often include hives, stomach cramps, difficulty in breathing, swelling of the face, lips, or throat, and dizziness or fainting. These symptoms can range from mild to potentially life-threatening anaphylaxis. Common food triggers for FDEIA include shellfish, nuts, wheat, and dairy, though any food can potentially be a trigger depending on the individual.
Regarding preventative measures, Gupta advised maintaining a detailed food diary, consulting with an allergist for proper testing and diagnosis, avoiding known allergenic foods before physical activity, and carrying an epinephrine auto-injector if diagnosed with FDEIA.
