What Could Cause Sudden Dark Vision With Dizziness When Standing After Long Period Of Sitting?

When I stand up after sitting for an extended amount of time, my vision starts to go dark from the outside in, followed by dizziness. This happens at a max of 2 times a day and has been going on for quite some time. If anybody has information on this subject, I would be glad to hear about it.

Hello
It seems from the history that you are having episodes of dizziness and dark vision after standing from sitting position.
This indicates transient ischemic attack and it is probably because of anemia, hypotension, hypovolemia...
Hence this requires evaluation to find out the underlying cause and treatment accordingly.

Thank you
