If the syncope is prolonged, it can trigger a seizure. You may suffer from a simple fainting spell due to anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs. Most people who suffer from simple fainting have no underlying heart or neurological (nerve or brain) problem.
People faint at the sight of blood. Parents faint when their kids get immunized. Older people faint in church. Many types of emotional and physical stressors can stimulate the vagus nerve to do damage. But on occasion, the cause of the faint is not vasovagal syncope but something more serious. Encouraging the person to seek medical care or calling 911 may save a life. While it may be an inconvenience or sometimes an embarrassment to a patient, being unconscious is not normal.
