The symptoms are typical of orthostatic hypotension not uncommon for
being in our 70s. It may be a warning that you need to consult your primary
physician for some in office testing. Your home health aid could assist you
in checking your pressure after lying down quietly for 5 minutes. Then with
the cuff in place have them recheck your pressure standing with arm at heart
level resting on their shoulder at one minute and again at 3 minutes.
If systolic drops 20 or diastolic drops 10 that is suggestive.
Medications are most frequently the cause.
Be wary of increased fall risk. I’m revisiting my cardiologist next week
for this issue. I have poor heart rate response from autoimmune problems.
