Exercise Can Trigger Allergic Reactions to Foods in Rare Health Condition

An active lifestyle with sports is often recommended for good health. However, for some, a lesser-known but serious health risk exists. Food Dependent Exercise Induced Anaphylaxis (FDEIA) is a condition where physical activity triggers an allergic reaction to certain foods consumed before exercising.

In a recent case at Sir Ganga Ram Hospital, a 12-year-old boy, who had always been healthy, experienced severe symptoms after eating shrimp salad and then playing cricket. Just ten minutes into the game, he suffered from intense itching, swelling, and difficulty breathing.

Understanding FDEIA

Dr Neeraj Gupta, Allergist, Pediatric Intensivist and Sleep Specialist, and Senior Consultant at the hospital, explained the boy's condition. "The boy was rushed to a nearby hospital where doctors recognised the signs of anaphylaxis," Dr Gupta said. Follow-up allergy testing revealed that his condition was triggered by a combination of shrimp consumption and exercise - a classic case of Food Dependent Exercise Induced Anaphylaxis.

Dr Gupta elaborated on FDEIA: "FDEIA is a condition where physical exercise triggers an allergic reaction to certain foods consumed before the activity." Unlike typical food allergies that are triggered immediately after ingestion, FDEIA requires both eating allergenic food and subsequent exercise to provoke symptoms.

Symptoms and Triggers

Symptoms of FDEIA can vary but often include hives, stomach cramps, difficulty breathing, swelling of the face, lips, or throat, and dizziness or fainting. Common food triggers for FDEIA include shellfish, nuts, wheat, and dairy. However, any food can potentially be a trigger depending on the individual.

These symptoms can range from mild hives and stomach cramps to potentially life-threatening anaphylaxis. Dr Gupta noted that understanding these symptoms is crucial for timely intervention and management of the condition.

Preventative Measures

Discussing preventative measures, Dr Gupta advised people to keep a detailed food diary and consult with an allergist for proper testing and diagnosis. He also recommended avoiding known allergenic foods before physical activity and carrying an epinephrine auto-injector if diagnosed with FDEIA.

Dr Gupta emphasised the importance of awareness about this condition among individuals who lead active lifestyles. Proper diagnosis and management can help prevent severe allergic reactions triggered by exercise following the consumption of specific foods.

This case highlights the need for increased awareness about FDEIA among both medical professionals and the general public. Recognising the symptoms early can be life-saving for those affected by this rare but serious condition.
