Or do you just mean low BP that is detected by a regular arm cuff device?
Orthostatic hypotension, as described to me, is a defect in the spontaneous response of baroreceptors to increase catecholamines (epenepherine/norepinepherine)and catech(?) This response would rapidly restore blood pressure upon standing. Pumping the blood from the legs back up to the heart.
A defect in this response prevents BP from rising adequately-thus orthostatic hypotension.
I test my BP lying down, sitting and then standing. The BP is quite high lying down 153-166/88-99.
When I stand up, the systolic drops 15-25 points. Diastolic changes only 5 points up or down.
But, I get lightheaded, dizzy, hear my pulse in my ears, and get a terrible headache. Am assuming this rapid drop in blood pressure is what's causing my symptoms.
imroswell is on track with pinning down what specific conditions are triggering the headaches. It is her approach i was trying to describe in my Answer. Be a detective in most chronic situations and don't be so tied up in the diagnosis. of course I am assuming a medical workup has failed to make a real diagnosis. Sometimes diagnoses get in the way of figuring out what is causing a symptom. Good luck to all of you.
