Fainting (syncope) is the partial or complete loss of consciousness with disruption of awareness of oneself and one's surroundings. It is followed by spontaneous recovery to full wakefulness. Syncopal episodes may occur suddenly with or without preceding signs or symptoms like dizziness, lightheadedness, nausea, and visual disturbances.
The most common triggers for syncope include standing for long periods of time, exposure to heat, the sight of blood, fear, anxiety, or physical strain. Syncope can also occur due to any underlying condition affecting the heart or the nervous system. While syncope can occur to anyone, men above the age of 60 years are at a higher risk.
The best way to prevent syncope is to avoid the triggers, stay hydrated, eat meals on time, and not over-exert oneselves.
Fainting is relatively common and not life-threatening. However, some causes of fainting can be a warning sign of an underlying disease which needs proper diagnosis and treatment to prevent any episodes in the future.
