Sorry you have this problem. My blood pressure numbers are a lot like yours, but not based on position, and systolic is often higher than 150. I don’t have much to suggest that could help you. But I wonder if you have done autonomic nervous system testing?

Hi @mariepresti . Thank you for commenting! Swift changes in blood pressure has to be super scary.

You mention medication dosing may be a factor. One idea as you wait for input from others might be to go to your pharmacist and ask them for guidance. What medication(s) do you take, and does more than one doctor prescribe them?

Your medication profile is most important. I’m hoping you have a primary physician to work with. The first step is for you to ask them to eliminate any medication or OTC that
might be causing low BP. If that is not the cause heart function and rate testing with monitoring is next. Diabetes
is implicated in one type of hypotension. This situation can occur in some patients with hypertension under treatment with several drugs.
The autonomic nervous system controls blood pressure. It is sometimes due to a neurological disorder.
You are at risk of fall or cardiovascular event so be sure to
consult your doctor or clinic promptly. Consulting your pharmacist about side effects and drug interactions is also
helpful when you are on multiple meds.
There are drugs to treat orthostatic hypotension if that is a problem after diagnosis is confirmed.
