Syncope, also known as fainting, passing out and swooning, is defined as a short loss of consciousness and muscle strength, characterized by a fast onset, short duration, and spontaneous recovery. It is due to a decrease in blood flow to the entire brain usually from low blood pressure.
Fainting is loss of consciousness caused by a temporary lack of oxygen to the brain. Known by the medical term syncope, fainting may be preceded by dizziness, nausea, or a feeling of extreme weakness. When a person faints, the loss of consciousness is brief. The person will wake up as soon as normal blood flow is restored to the brain. Blood flow is usually restored by lying flat for a short time.
