General & Family Physician 's  Response
Hello,

Let me tell you that a blackout is a temporary loss of consciousness. There are three major reasons why people experience blackouts.
a.Syncope,which is a sudden lack of blood supply to the brain. Syncope is caused by a problem in the regulation of blood pressure or by a problem with the heart.
b.Epilepsy
c. Psychogenic blackouts resulting from stress or anxiety.
I suggest talk to her doctor for a diagnosis.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Prabhash Verma, General & Family Physician
