Presyncope is the sensation of feeling light-headed or as though you’re about to faint, but without actually losing consciousness. Sometimes referred to as near syncope, presyncope occurs when blood flow to the brain temporarily decreases, causing the feeling of faintness. Unlike syncope, which is the medical term for fainting, presyncope doesn’t involve a complete loss of consciousness.
Presyncope can last anywhere from a few seconds to a few minutes. While it’s often not serious for many individuals, it can be an indicator of underlying health issues. For a small percentage of people, presyncope may be a warning sign of heart problems like arrhythmias, or low blood pressure, both of which can lead to more severe consequences, including fainting or injury from a fall.
