Symptoms of fainting and causes
Last Update: 23 Mar 2011 08:51 AM





Fainting occurs due to decreased blood supply to brain and is usually very brief. It may not have medical significance or the cause can be a serious disorder. Therefore, treat loss of consciousness as a medical emergency until the symptoms are relieved and the cause is identified.

Symptoms:
Before fainting, you may experience the following:
  • Rapid heart beat or palpitations
  • Dim vision
  • Nausea
  • Excessive sweating

What to do if you feel faint?

  • Lie down, or sit down and position your head between your knees.
  • If fainting is associated with a fall, treat any bumps, bruises or cuts. Control bleeding with direct pressure.
  • If the fainting spells continue to occur, inform a physician.
 

What to do if someone else faints?

  • Position them on their back.
  • Check to see if airways are clear.
  • Restore blood flow by loosening clothing/belts/collars.
  • Elevate feet above head level.
  • Check if breathing/pulse is normal.
  • If circulation or breathing is absent begin CPR.
  • Call 997 or your local emergency number. Continue CPR until help arrives or the person responds and begins to breathe.
