Fainting

Simple fainting (Benign Vasovagal Syncope)

This is the commonest cause of syncope in all age groups.

It occurs most frequently in young adults. It rarely presents for the first time in older people.

Attacks are precipitated by recognised triggers such as fear, severe pain, sight of blood etc., and are associated with prodromal (warning) nausea, sweating, and pallor. Injury is unusual.
