Orthostatic hypotension (also called postural hypotension) is a sudden fall in blood pressure that occurs upon standing quickly. Blood pressure is the force of your blood against the walls of your arteries (the blood vessels that carry blood from the heart through the body). Hypotension is the term for low blood pressure. When you stand up, gravity pulls blood into your legs, and your blood pressure begins to fall. Certain reflexes in your body compensate for this change. Your heart beats faster to pump more blood, and your blood vessels constrict to prevent blood from pooling in your legs.
