Do You Get Dizzy When You Stand Up?

Playing Should You Be Concerned about Dizziness When Standing?

A viewer tweets The Doctors that he or she doesn’t have low blood pressure, but often after long periods of sitting gets dizzy upon standing. “Why does this happen and should I be concerned?”

Family physician Dr. Mike Varshavski says this sounds like postural hypotension which is low blood pressure upon standing. He explains that as we get older we are more susceptible to changes in blood pressure. While seated, our blood pressure drops a bit because our body doesn’t need as much pressure to get the blood to the brain. Upon standing, your body has to react very quickly because the receptors in your legs need more pressure and respond, which can lead to this dizziness.
