Black Out

Black Out

Blackout is a condition characterized by the temporary loss of consciousness and muscle strength, usually caused by a lack of oxygen supply to the brain. It is also known as fainting, passing out and syncope. Pre-warning symptoms of a blackout include lightheadedness, dizziness, blurred vision, a feeling of weakness and palpitations. Sometimes, chest pain and shortness of breath may be experienced too.


Common causes of a blackout include low blood pressure, heart arrhythmias, heart valve problems, heart attack, anaemia, dehydration, low blood sugar, certain medications and neurological conditions.

Medications may be recommended to help regulate heart rate and blood pressure although, in some cases, the insertion of a pacemaker or other cardiovascular procedures may be required.

Dr Costopoulos can diagnose and treat underlying cardiovascular issues which may lead to blackouts as well as advising on lifestyle and medication.
