Citat:
Here's the key point: What do you think is happening to your blood pressure during a panic attack?
It's going up. Probably not a lot, but it's doing the opposite of what you need to faint. So it's extremely difficult to faint during a panic attack. In order to faint during a panic attack, you need to have some other physical circumstance or condition which lowers your blood pressure to such a degree that it overcomes the increase.
It's not impossible, but extremely rare. Some people have a condition, called a syncope, which can result in a faint during panic. If you have such a condition, you would probably have a history of actual faints (not "almost fainting", actual faints) by the time you're in your thirties. Some people have what's called a Blood Phobia, and they can faint when they see blood. That's not an uncommon condition, but it's very different from Panic Disorder.
In more than 20 years of treating patients with Panic Disorder, I've seen four who had actual fainting episodes. Certainly it was of little comfort to them that it was so rare and, if you have a history of actual fainting episodes, you have to learn how to manage them and protect yourself. But if what you have is a history of fearing a faint, of feeling like you were about to faint, of thinking you just narrowly dodged a faint, and so on, in the absence of any actual fainting episodes, then what you are troubled by is a fear of fainting in the absence of any actual fainting.
While fainting almost never occurs, the fear of fainting is extremely common among people with Panic Disorder. This is because people often feel dizzy and lightheaded during a panic attack, and mistakenly associate this with fainting. People who have never fainted in their lives will say "it feels like fainting".
