- Dizziness or light-headedness when standing up occurs as a result of abnormal blood pressure regulation. Normally, when people stand, gravity causes blood to pool in the veins of the legs and trunk. This pooling lowers the blood pressure and the amount of blood the heart pumps to the brain. Low blood flow to the brain causes the dizziness and other symptoms. To compensate, the nervous system quickly increases the heart rate and constricts blood vessels, which rapidly returns blood pressure to normal before symptoms can develop.
