7.Cause: Standing for Long Periods
After you’re on your feet for a while, blood can start to pool in your legs. If your brain doesn’t tell your heart to pump enough to keep your blood pressure up, it might drop low enough to make you dizzy and nauseous. You might even pass out. Your doctor might call this «neurally mediated hypotension.» Like a bad relationship, the problem is poor communication, in this case, between the heart and brain.
8.Getting a Diagnosis
Once your doctor knows your symptoms, blood tests can help diagnose the reason for your low blood pressure. An electrocardiogram, ultrasound, and other tests check your heart health. The Valsalva maneuver observes nerve signals that control your heart and blood vessels, and a «tilt table» test looks at how your body responds to position changes.
