Medical News Today: What to know about vasovagal syncope

The term vasovagal syncope describes fainting that occurs in response to a sudden drop in heart rate or blood pressure. The resulting lack of blood and oxygen to the brain is what causes a person to pass out.

Doctors sometimes refer to vasovagal syncope (VVS) as neurocardiogenic syncope or reflex syncope. This condition typically occurs when the body overreacts to a stimulus that induces a state of fear or emotional distress.

Other causes may include severe pain, exhaustion, or sudden changes in body posture. Some people have a predisposition to these episodes due to a health condition that affects blood pressure or the heart.

Although a person may sometimes sustain injuries as a result of passing out, VVS is generally harmless. However, a medical diagnosis is necessary to rule out more serious medical conditions.

In this article, we outline some common symptoms and causes of vasovagal syncope. We also cover the treatment options available and provide tips on how to prevent fainting episodes.
