What Causes Blackouts?

detailed below.
Detailed Answer:
Hello,
Welcome to Healthcare Magic.
Blackouts (Syncope) are caused by a temporary reduction in the blood flow to the brain.
There are many possible causes for blackout but the most common ones are:
-Postural hypotension.In this condition there is a reduction of the blood pressure when a person stand up quickly from a lying position ,causing a reduction of the blood flow to the brain.
-Heart conditions (arrhythmia or structural heart condition).
-Vasovagal syncope
-Low blood pressure (hypotension).
-Seizures
If you are having frequent episodes of blackouts ,you need to consult a physician for complete evaluation.A detailed medical history and physical examination is necessary.
The doctor may order some tests like complete blood count,blood sugar, ECG and stress test or heart ultrasound to exclude heart conditions.
Depending on the findings of the tests and physical examination ,further investigations might be necessary.
Hope it helps.
Let me know if you have any other question.I will be happy to help.
Kind regards,
Dr.Rovena Murati
