Overview

Vasovagal Syncope is a common condition that causes sudden fainting due to a temporary drop in heart rate and blood pressure. This reduces blood flow to the brain, leading to loss of consciousness.

It is usually triggered by stress, pain, prolonged standing, or dehydration. Although vasovagal syncope is generally harmless, recurrent episodes may require medical evaluation and management.
