The medical term for fainting is syncope. (See related link.)

Generally, fainting is merely a temporary loss of consciousness. Generally, this is a consequence of a temporary drop in blood flow to the brain and lasts a few minutes.

When you faint, you lose consciousness (People say you "black out.") and lose muscle tone for a short time and then recover spontaneously when blood flow and blood pressure return to normal. Generally, there are no long term effects if there are no complicating factors of an injury or disease state.

There are many possible causes of fainting varying from momentary changes of blood pressure under stress to serious chronic disease states. (See related link.)
