It is important to figure out what triggered the fainting episode and prevent it from happening again. • Anybody with a recurring episode of fainting should seek medical care. • CAUSES • Fainting is most commonly caused by a temporary glitch in the part of the nervous system that controls heart rate and blood pressure, usually in response to a trigger. This may cause the heart rate and blood pressure to drop suddenly, leading to reduced blood flow the brain, and in turn, resulting in a brief loss of consciousness. This type is called neurocardiogenic syncope. Common triggers of neurocardiogenic include: • Seeing blood • Heat exposure • Standing still for long periods of time • An unpleasant sight • Sitting suddenly • Sudden emotional upset such as when receiving bad news • Extreme embarrassment • Fear of bodily injury • Fainting can also result from a fall in blood pressure after standing up rapidly from a lying down or sited position, referred to as orthostatic hypotension. This condition is usually common in older adults, particularly those aged over 65. Possible triggers of orthostatic hypotension include: • Untreated diabetes • Alcohol • Medications for high blood pressure • Dehydration • Antidepressants • Neurological conditions such as Parkinson’s disease • Carotid sinus syndrome
