Loss of Consciousness

Unconsciousness is when a person suddenly becomes unable to respond to stimuli and appears to be asleep.

A person may be unconscious for a few seconds — as in fainting — or for longer periods of time, and most often they do not respond to loud sounds or shaking. They may even stop breathing or their pulse may become faint. When this happens, it is critical the person be taken to Clear Choice Emergency Room for an immediate assessment.

Common causes of unconsciousness include:

  • A car accident
  • Severe blood loss
  • A blow to the chest or head
  • A drug overdose
  • Alcohol poisoning


At Clear Choice Emergency Room, we’re open seven days a week, 365 days a year, and at any given time, you will be seen by a board-certified, highly experienced emergency care physician. When loss of consciousness occurs, the sooner the person receives emergency care, the better the outlook may be.
