4. Lightheadedness
Hypersensitivity reactions may also affect our state of mind and levels of alertness and consciousness. Many patients experience dizziness or lightheadedness, and there are some cases of fainting as well, sometimes associated with respiratory symptoms of anaphylaxis. In some cases, patients arrive to the emergency room in a state of confusion that is detected after asking the patient a series of questions about them, where they are, and so on. Thus, if you’re accompanying one of these patients to the emergency room, do not answer these questions to the doctor unless he’s directly addressing you.
