Prognosis of Orthostatic Hypotension

Orthostatic hypotension is defined as a fall of 20 mm or more in systolic blood pressure or of 10 mm or more in diastolic blood pressure within 3 minutes of standing [1]. All persons receiving antihypertensive drugs routinely should have their blood pressure measured in the sitting position and within 3 minutes of standing [2]. Blood pressure should not be taken immediately after eating as postprandial hypotension may occur at that time [3]. Orthostatic hypotension and postprandial hypotension may coexist, and both disorders are associated with adverse clinical outcomes [3].
