Why might your blood pressure drop when you stand up?

ANSWER

There are many reasons this shift can happen. You might be dehydrated, have low blood sugar, or be taking medication that changes your blood pressure. But some research suggests it could be an early sign that your heart isn’t pumping blood as well as it should.
