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.
Dr. Mike says there are other factors that could be causing this feeling such as how hot the room is, other activities someone has been doing, and illnesses, such as diabetes.
Dr. Mike adds that medications are often the cause of this. He shares that the recent proposed changes to blood pressure guidelines have become more aggressive in treating high blood pressure. He says if blood pressure drops too low it can be dangerous in older adults especially when this leads to an increased risk of falls.
OB/GYN Dr. Nita Landry says it’s also a big issue in pregnancy too. Dermatologist Dr. Sonia Batra adds that other factors that could lead to this dizziness are varicose veins, dehydration, and getting up too quickly after a procedure.
Dr. Mike says any kind of light-headedness or dizziness is something that should be checked out by a doctor.
