I feel light headed and woozy when I stand up abruptly, what could cause this?
Orthostatic hypotension also called postural hypotension is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make you feel dizzy or lightheaded, and maybe even cause you to faint.
It’s a common phenomenon with an uncommon name: orthostatic hypotension. It just means that when you shift from lying down or sitting to standing, your blood pressure drops and you momentarily feel a little woozy. That’s because blood pools in your legs temporarily when you stand up, and it takes the body a moment to compensate by squeezing blood out of the large veins in your legs and revving up the heart a bit. The dizziness may strike after you eat a meal, because digestion diverts blood flow and may lower your blood pressure.
