Syncope, or fainting, is a common phenomenon caused by a change in blood flow to the brain. It can be triggered by various factors and can affect anyone, but can also be a symptom of an underlying medical condition. It’s important to seek medical attention after a fainting episode.
Syncope is the correct medical terminology for a sudden loss of consciousness or fainting. While the underlying causes of syncope vary, the phenomenon is relatively common. It is likely that every person will experience a fainting episode with little or no warning at some point in their life.
The trigger for syncope can be something as simple as a sudden fright or shock. It is not uncommon for someone to faint on hearing of an unexpected event, such as the death of a loved one. Blackout can also occur when the mind and body sense some kind of imminent danger or threat and the individual is unable to escape the situation.
In terms of how a blackout affects the body, the condition is caused by a change in blood flow to the brain. There is often a substantial change in blood pressure resulting in the brain not getting a normal amount of blood into and out of the organ. This disruption of blood flow causes the individual to lose consciousness for a short period of time. When syncope is not due to some ongoing medical condition, it is usually easy to revive the individual within a short period of time.
Since fainting doesn’t have to be related to any underlying disease, the phenomenon can be experienced by anyone. People of all ages and genders can experience a fainting episode. Generally, actual fainting is preceded by a momentary stiffening of body posture before the person loses consciousness. The eyes may appear to roll back in the head just as the eyelids close and the body becomes floppy.
Syncope can also be a symptom of some type of medical condition, such as low blood pressure or even extreme anxiety disorder. When a fainting episode occurs, it’s important to see a doctor as soon as possible. While syncope is often a one-time event triggered by some unexpected stimulus, a thorough physical checkup will help ensure the event wasn’t a precursor to something more serious.
