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

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..

I agree with the above. Note that doctors do not use standing BP to determine if there is "high blood pressure" because everyone is higher standing, if they're healthy. A fall in BP when standing (orthostasis) is a sign of dehydration or more serious illness.
