Vasovagal syncope is a temporary loss of consciousness caused by a sudden drop in blood pressure and heart rate. This common condition occurs when your body overreacts to certain triggers, causing you to faint.

Common Causes and Risk Factors:

• Emotional distress
• Standing for long periods
• Heat exposure
• Dehydration
• Blood draws or injections
• Family history of fainting
• Heart conditions
• Certain medications
• Epilepsy
• Low blood sugar

Warning Signs Before Fainting:

• Lightheadedness
• Excess sweating
• Pale skin
• Nausea
• Tunnel vision
• Ringing in ears
• Feeling unusually warm

Diagnosis Methods:

• Medical history review
• Blood tests
• Electrocardiogram (EKG)
• Tilt table testing

Treatment Options:

• Avoiding known triggers
• Lying down when symptoms appear
• Increasing fluid and salt intake
• Medications (fludrocortisone or midorine)
• Pacemaker (in severe cases)

Prevention Strategies:

• Recognize early warning signs
• Stay hydrated
• Avoid prolonged standing
• Practice yoga
• Increase salt intake (under medical supervision)
• Keep cool in hot weather
• Lie down when feeling faint

Seek Immediate Medical Attention if:

• Person remains unconscious after 2 minutes
• Shows irregular heartbeat or chest pain
• Experiences seizures or loss of bodily control
• Is pregnant or over 50
• Sustains serious injury while fainting
• Has difficulty speaking or vision changes

While vasovagal syncope itself isn't typically dangerous, the circumstances of fainting can lead to injury. Most people recover quickly and don't require ongoing treatment, but frequent episodes should be evaluated by a healthcare provider to rule out underlying conditions.
