Causes of Syncope

If brain blood and oxygen levels drop, consider the shutting down of the brain to other non-vital parts of the body. When the brain detects lower levels of oxygen, the body will start breathing faster to bring levels back up again.

The heart rate will rise in order to get more oxygen into the brain. This results in hypotension in other parts of the body, because the brain is flooded with blood.

Hyperventilation with hypotension may cause short term loss of perception, weakening of muscles, and syncope.
