If the syncope is prolonged, it can trigger a seizure. You may suffer from a simple fainting spell due to anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs. Most people who suffer from simple fainting have no underlying heart or neurological (nerve or brain) problem.
Loss of intravascular fluid, that is the blood and water within the blood vessels, can also cause fainting or syncope. Usually, fainting will occur when a person stands up quickly from a lying or sitting position and there isn't enough time for the body to compensate by making the heart beat quicker, or having the blood vessels constrict to maintain the body's blood pressure and blood flow to the brain.
