A member asked:

I'm getting dizziness and tunnel vision upon standing, what can cause this?

A doctor has provided 1 answer

Blood flow!: Decreased blood flow to the brain can cuase these symptoms. Usually exacerbated when changing from lying or sitting position to standing. You may have a problem with your vertebral basilar arterial system. You need to see an ophthalmolgist or your pcp.
