Why does my vision suddenly turn black when i stand up?
A doctor has provided 1 answer
Vascular instability: This could be from postural hypotension (pooling of the blood away from the brain on standing), or anemia, or certain blood vessel or heart issues. Check with your internist or family doctor to get to the root cause of this.
