A member asked:

Woman, 87, with low-to-normal bp while sitting & elevated bp when standing - why the big difference?

A doctor has provided 1 answer

Normal response: This normal for your body to do that...The blood pressure should even lower when you laying flat to sleep at night.. Standing up means you are physically taller than sitting and thus needing more pressure to get blood up to your head..
