What is Passing Out?

Passing out or syncope is a condition in which one loses consciousness for a brief period of time. This is caused by a lack of oxygen and blood flow to the brain necessary for the body to function properly. Symptoms that may be experienced before passing out include dizziness, lightheadedness, feeling clammy, fatigue, changes in hearing, weakness, and nausea.
