Syncope, commonly known as fainting or passing out, is a loss of consciousness and muscle strength characterized by fast onset, short duration, and spontaneous recovery. It is caused by a decrease in blood flow to the brain, typically from low blood pressure, and is sometimes preceded by symptoms such as lightheadedness, sweating, pale skin, blurred vision, nausea, vomiting, or feeling warm. When consciousness and muscle strength are not completely lost, it is called presyncope, which is recommended to be treated the same as syncope.
