6 signs you're about to pass out and why it happens |
Fainting is one of the most common issues emergency medicine doctors see. "Passing out can be all the way from completely benign — you got a little bit woozy when you saw some blood — all the way up to life-threatening — your heart wasn't beating correctly,"says Dr. Torree McGowan, an emergency medicine physician in Culver, Oregon. Passing out with absolutely no warning is uncommon, but when it happens, doctors worry about heart rhythm problems — a more serious cause of fainting, McGowan adds. Most people will have symptoms when they're about to lose consciousness, she notes. They include: - Feeling dizzy, nauseated or lightheaded.
- Having cold or clammy, sweaty skin.
- Experiencing visual changes such as tunnel vision, vision that blurs or goes dark, or seeing spots. People around you might notice you have dilated pupils.
- Feeling a sensation of warmth — "It feels like your whole body blushes," says Bri Clark, the Tennessee woman who passed out. "My whole body got really tingly."
- Turning pale.
- Experiencing shortness of breath.
