Orthostatic Hypotension

Orthostatic hypotension is a condition characterized by a significant drop in blood pressure when moving to a standing position. This can lead to lightheadedness or fainting. It's important to consider how changes in position affect overall well-being and daily activities.

  • What exactly is orthostatic hypotension?
    MedlinePlusMay 2026

    Orthostatic hypotension is when your blood pressure drops too low when you stand up quickly, causing dizziness or lightheadedness. It happens because your body doesn't adjust your blood pressure fast enough as you change positions.

  • Why does my blood pressure drop when I stand up?
    MedlinePlusMay 2026

    When you stand up, gravity pulls blood down into your legs, so your heart has to work harder to pump blood to your brain. If your body doesn't react quickly enough, your blood pressure can drop before it adjusts.

  • How common are symptoms like dizziness or fainting?
    MedlinePlusMay 2026

    Many people with orthostatic hypotension feel dizzy or lightheaded when standing up, but not everyone faints. Symptoms only become a real problem if they cause you to fall or lose consciousness.

  • Is there a difference between having low blood pressure all the time and just sometimes?
    MedlinePlusMay 2026

    Yes—some people have low blood pressure all the time with no symptoms, while others only experience drops when standing up. For some people, low readings are normal and harmless, but for others it's caused by a medical condition or medicine.
