Fainting (syncope) is a temporary loss of consciousness ("passing out"). It occurs when blood flow to the brain is reduced. Your doctor believes that your episode was due to a common vagal reaction. A vagal reaction is a reflex response that causes the pulse to slow down. If the pulse is low enough, the blood pressure falls and causes fainting or near-fainting. Lying down usually stops the reaction within 60 seconds.
This reflex response can occur during sudden fear, severe pain, emotional stress, overexertion or suddenly standing up after sitting or lying for a long time.
1) Rest today and resume your normal activities as soon as you are feeling back to normal.
2) If you become light-headed or dizzy, lie down immediately or sit with your head lowered between your knees.
with your doctor as instructed.
