Why would you feel dizzy when you stand up? |
[Edit] |
Orthostatic Hypotension
Usually this happens when you stand up after sitting or laying down for a long time; blood rushes out of your brain for a brief moment because your heart needs to pump harder when you are standing. This causes the dizziness, or in extreme cases, fainting.
This condition is also known as orthostatic hypotension.
