Introduction: Food-dependent exercise-induced anaphylaxis (FDEIA) is a rare condition. It is characterized by the development of anaphylactic symptoms only if exercise takes place within a few hours of eating. Wheat is the most commonly described food allergen in this situation. Case report: Male 14 years old adolescent, admitted in the hospital with symptoms of nausea, generalized maculopapular rash, bilateral hand edema and syncope. The symptoms took place during exercise, shortly after eating. The patient denied similar episodes with physical exertion or food ingestion alone. Laboratory studies demonstrated a total IgE > 1000 KU/L, as well as the presence of specific IgE for wheat, peanut, soy, olive tree, eucalyptus, parietaria, acacia and pine tree. The baseline serum tryptase level was normal. The patient was diagnosed with a likely FDEIA and instructed to carry an epinephrine autoinjector device as well as not performing exercise until four hours after wheat ingestion. He did not undergo an exercise challenge test. Discussion: FDEIA diagnosis is based  on  a  thorough clinical history and exclusion of differential diagnosis, and an exercise challenge can be confirmatory. It is important to remember that food ingestion or exercise alone is not forbidden, thus avoiding restrictive diets and unnecessary lifestyle changes.
