Blackouts

A blackout, or a faint, is a sudden loss of consciousness caused by a temporary shortage of blood and oxygen to the brain.

Identifying the causes of blackouts is important for keeping you safe and well. 

Recognising Blackouts

Blackouts can sometimes be challenging to identify, particularly when they are brief. However, it's essential to suspect a blackout if:

• You fell and cannot remember what happened.
• You have injuries to your face, indicating that you may not have had a chance to put your hands out to save yourself.

Common Causes of Blackouts

Blackouts become more common as we age, and they can result from a number of things, including:

• Drop in blood pressure - A sudden drop in blood pressure, often experienced when changing position (e.g., standing up from a chair).
• Heart disorders - Certain heart conditions or irregularities in heart rhythm.
• Anxiety, panic attacks, or stress - Emotional factors such as anxiety, panic attacks, or stress can trigger blackouts in some individuals.

Taking Action

If you suspect that you may have had a blackout, it’s essential to tell your GP as soon as possible. This will help with finding the cause and choosing the right treatment to prevent future episodes.
