2. What Happens During Vasovagal Syncope? The Underlying Mechanism
Vasovagal syncope is triggered when the vasovagal nerve, which regulates heart rate and blood pressure, overreacts. This overreaction causes the heart rate to slow down and the blood vessels in the legs to widen, leading to blood pooling in the lower extremities. Consequently, blood pressure drops, reducing blood flow to the brain and causing fainting. The mechanism involves the autonomic nervous system’s response to certain stimuli.
3. Common Triggers of Vasovagal Syncope: Identifying Potential Causes
Several triggers can lead to vasovagal syncope, including:
- Prolonged standing
- Exposure to heat
- Seeing blood
- Having blood drawn
- Fear of bodily injury
- Straining (e.g., during bowel movements)
- Emotional distress
Identifying and avoiding these triggers can help prevent episodes.
4. Recognizing the Symptoms of Vasovagal Syncope: What to Watch For
Before fainting, individuals may experience:
- Lightheadedness
- Tunnel vision
- Nausea or upset stomach
- Feeling warm
- Cold, clammy sweat
