Syncope

Syncope is a temporary loss of consciousness, commonly known as fainting, that occurs when blood flow to the brain briefly decreases. Recovery is usually quick and spontaneous.

Before seeking care, it helps to know: Although many episodes are benign, having them repeatedly, having them appear during physical exertion, or without any prior warning are reasons to have them evaluated, since this helps rule out causes that require follow-up.

Possible triggers: It may be associated with sudden changes in posture, prolonged fasting, dehydration, intense emotions, or, in some cases, disturbances in the heart's rhythm.

Which specialist evaluates it? The cardiologist investigates its possible cardiac origin, and in childhood the pediatric cardiologist and the pediatrician take part in its study. If you have repeated or unexplained fainting episodes, the sensible thing is to schedule a medical evaluation without putting it off.
