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.

Preventing Blackouts and Staying Safe

There are some practical steps you can take to reduce the risk of having a blackout, including:

• Stay well-hydrated - Dehydration can affect your blood pressure, so make sure you drink enough water.
• Sit or stand up slowly - When changing positions, do so slowly to minimise sudden changes in blood pressure.
• Manage stress and anxiety - Consider techniques such as relaxation exercises, mindfulness, or counselling to address emotional triggers.
• Follow your GP's recommendations - If you have a medical condition contributing to blackouts, follow your doctor's advice and treatment plan.

Remember, addressing the potential causes of blackouts can help you stay safe and maintain your overall well-being. By seeking medical guidance and taking preventive measures, you can reduce the risk of blackouts and enjoy a healthier and more active life.
