Syncope means fainting or passing out. When fainting is caused by certain triggers, like the sight of blood or a needle, or an intense emotion like fear or fright, it’s called vasovagal syncope. It’s the most common cause of fainting.
Vasovagal syncope is sometimes referred to as a neurocardiogenic or reflex syncope.
Anyone can experience vasovagal syncope, but it tends to be more common in children and young adults. This type of fainting happens to men and women in equal numbers.
Although some causes of fainting can be a sign of a more serious health problem, that’s typically not the case with vasovagal syncope.
This article will cover the causes, diagnosis, and treatment for vasovagal syncope, as well as signs that you should see a doctor.
