ORTHOSTATIC HYPOTENSION · OH

Does everything go dark
when you stand up?

Orthostatic hypotension (OH) is a condition in which blood pressure drops excessively when you stand up. Even if your usual blood pressure is normal, blood pressure and symptoms need to be checked together after a change in posture.

We check when the blood pressure drops

You may notice blurred vision, a feeling that you are about to faint, or weakness on standing. Because there are differences by timing, such as initial, classic, and delayed types, when it starts and how long it lasts are important.

We review medications, hydration, and the autonomic nervous system

After checking how symptoms relate to blood pressure, we distinguish correctable factors such as medications or dehydration from autonomic causes. When needed, we connect you with evaluation in other departments.

At your visit, please tell us your blood pressure and pulse before and after standing, your list of medications, and whether you have fainted or fallen.

Care to prevent fainting and falls

If you feel dizzy, sit or lie down safely to avoid falling. Treatment is individualized, taking into account the cause and even your blood pressure when lying down.

Fluid and salt adjustments and medication changes depend on whether you have heart or kidney disease or high blood pressure, so they should be discussed with the medical team.

FAQ

If my usual blood pressure is normal, can I still have orthostatic hypotension?

Your blood pressure at rest and after standing can differ. We compare blood pressure lying down and after standing, and judge it together with your symptoms.

Can dizziness occur only right after standing and then pass quickly?

Yes. Very rapid blood pressure changes can be missed by ordinary intermittent measurements. Please tell the medical team how long it takes for symptoms to start and to recover.

Will I get better if I stop my blood pressure medication?

Medications can play a role, but stopping them on your own can be dangerous. Bring your prescriptions and a record of your symptoms, and discuss whether your medication needs adjusting.
