In medicine, orthostatic hypotension is "a significant drop in blood pressure after assuming a standing position. Orthostatic hypotension is a finding, and defined as a 20-mm hg decrease in systolic pressure or a 10-mm hg decrease in diastolic pressure 3 minutes after the person has risen from supine to standing. Symptoms generally include dizziness, blurred vision, and syncope."[1]

Bilateral endarterectomy of the internal carotid artery may be a cause.[2]
