10 Causes of Syncope

Cause #8: Standing Too Quickly
In addition to our heart acting as a pump, our circulatory system also uses a system of valves to help keep the blood flowing in the right direction. This system helps to push the blood back up through the body against the effects of gravity and is essential to keep oxygenated blood moving throughout the body.
Even though the circulatory system is effective in day to day operations, it is possible to place it under too much pressure. Stand up too quickly and you will find that the sudden increased pull of gravity on your blood temporarily reduces the oxygen flow to the uppermost part of your body… the head. This temporary lapse of oxygen in the brain can lead to syncope.
