title: [Intolerance as consequence of hyperreactivity].
abstract: Many patients complain about hyperreactivity of the skin or mucosal membranes, whereby rather harmless "triggers" lead to exaggerated reactions like running nose, bronchospasm, urticaria, etc. Most of these hyperreactivities have an underlying inflammation. It is important not to focus only on the triggers, but to look for the agent causing the inflammation and to avoid/treat it: elimination of the cause also eliminates the hyperreactivity. Four examples are presented where this cause--trigger model of hyperreactivity is illustrated (exercise induced asthma, pollen associated food allergy, flare-up reactions in drug allergy and hyperreactivity in chronic urticaria).
