passage 1
Many patient complain of having had a 'blackout'_ a loss of consciosness for a few minutes_ but this is certainly an overused word. Patients will sometimes report having had an attack, so relatives will be suitably impressed. It is critical to separate the genuine loss of consciosness from the supposed one. In a fske faint, the patient's description is very vague and may often have gone for up to an hour. They say they felt dizzy and thought they were going ti "pass out". During a genuine faint, the attack is usually very short and is often caused by some emotional upset. Waiting to see the dentist, taking one's turn in a blood transfusion clinic, and having varicose veins treated are typical causes. Occasionally, a bleeding stomach ulcer may cause loss of consciousness and, if the patient is taking insulin or having injections for diabetes, a shortage of sugar in the blood may lead to a sudden passing out too. First Aid manuals emphasize that those around the patient keep him quiet and well supplied with fresh air, and also get immediate expert advice if there is no obvious cause, attacks recur, or the patient is over 30.
