Rate: (Click the stars to rate) Published on Mar 23, 2010 by Ask VideoMD, Views: 8822 Orthostatic hypotension occurs when you go from a lying or sitting position to a standing position. It occurs because blood pools in the legs, and lowers the blood pressure. The symptoms are lightheadedness and dizziness. You should make sure to stay well hydrated, and be sure to have something to hold on to when you get out of bed, to avoid falling. Question from HealthEagle.com Dr. Heller, Please tell us more about blood pressure. I am first learning about it and want to know more. Does drinking alcohol hurt you if you have high blood pressure? grandla 11 years ago Thanks Dr. Heller, I have heard a lot about you and what a great doctor you are. In this day and age, we need more docs like you who are committed to greatness. balloonsky 11 years ago You are so handsome...........I wish you were my doctor. I get light headed when I get up quickly. Maybe I am taking too much meds for high blood pressure. Please respond. Nadia 11 years ago
