Low Blood Pressure Standing: Causes, Risks, and What to Do

When you stand up too fast and feel lightheaded, dizzy, or like you might pass out, you’re likely experiencing orthostatic hypotension, a sudden drop in blood pressure that happens when standing up from sitting or lying down. Also known as low blood pressure standing, this isn’t just a minor annoyance—it’s your body struggling to keep blood flowing to your brain fast enough. It’s not rare. Millions of people deal with it daily, especially as they age, take certain medications, or have underlying health issues like diabetes or heart conditions.

This isn’t just about getting up too quickly. dehydration, not having enough fluids in your body is a top trigger. So is medications, including those for high blood pressure, heart problems, or depression. Even long periods of bed rest or pregnancy can throw your system off. When your blood pressure drops too fast, your heart and blood vessels don’t respond quickly enough, leaving your brain short on oxygen. That’s what causes the foggy head, blurred vision, or sudden weakness.

Repeated episodes increase the chance of falls, injuries, or even fainting in dangerous situations—like while driving or climbing stairs. If it happens often, you need to understand why.
