Food-dependent exercise-induced anaphylaxis-sequence of causative factors might be reversed.

We present a case of a 27-years-old female who experienced several episodes of food-dependent exercise-induced anaphylaxis (FDEIA). Besides two typical episodes of FDEIA triggered by a postprandial physical exercise, she also experienced atypical episodes in which the sequence of the causative stimuli was clearly reversed-clinical symptoms which appeared after a prolonged exercise, followed by ingestion of the sensitizing food. This unusual clinical picture entitled us to extend the routine recommendations-avoidance of the coincidence of food allergens intake and exercise accordingly to her history.
