Fainting is a temporary loss of consciousness that usually lasts a few seconds or minutes, then the person wakes up. The care receiver may have warning symptoms of dizziness preceding a fainting episode.
Fainting is caused by a decrease in blood flow to the brain. There’s a wide range of different factors that could cause this reduction in blood flow that leads to fainting.
Many people who faint will recover quickly and not suffer any long-term health effects. But it’s never good to assume. Always seek professional medical advice after any fainting spell to ensure that it’s not a result of an underlying condition, or if it is, how you can deal with it.
