Fainting is a spontaneous loss of consciousness, and could result in passing or blacking out.
What causes fainting?
Fainting is usually a result of a combination of factors, including low blood pressure or low blood sugar, which can cause dizziness or lightheadedness.
If you feel dizzy or lightheaded, it’s a good idea not to get up too quickly, as this could bring on a fainting spell. Staying properly hydrated and maintaining a healthy diet can help prevent fainting. If you do faint or often feel dizzy, you should let your healthcare provider know right away.
