Syncope, also known as faint, is a temporary loss of consciousness and balance usually related to insufficient blood flow to the brain. The majority of syncope patients are those whose the autonomic nervous system (Vasovagal Syncope) works unusually.

Possible causes of syncope:
  • Lack of blood and oxygen to the brain
  • The autonomic nervous system works unusually
  • Carotid artery disease
  • Cardiac dysrhythmia
  • Lack of sleep
  • Dehydration
  • Medications used

The syncope could be triggered under different circumstances such as urinating, bowel movement, swallowing food, coughing or sneezing and during emotional situation; such as fear of drawing blood or injection. It causes your heart rate and blood pressure drop suddenly, causing you to briefly lose consciousness.

Even though, the condition itself might not be harmful but it could be dangerous if a person fall unconscious while working on high risk environment such as driver, pilot and construction worker.
It is necessary to take syncope patient to hospital and receive special diagnosis. Physicians can detect these disorders with an electrocardiogram (ECG or EKG), which measures the electrical activity of the heart in order to know the cause of syncope whether it came from serious cardiac issue or not.

You can prevent the syncope condition by concerning good diet, exercise regularly, get enough sleep and drinking water.
