A member asked:
My blood pressure sitting down is 140/100 laying down it is 129/76. why do i get such a huge difference between sitting and laying down?

Orthostatic: Your blood pressure normally will increase a little when you go from lying to sitting to standing. This is to overcome the extra resistance partly due to gravity. However, your numbers are higher than they should be. This is called orthostasis ; usually due to dehydration. If it persists even after drinking some water, you may have kidney, hormonal, or carotid disease that should be checked out.
