The ANS normally controls constriction (narrowing) and dilation (widening) of blood vessels and so helps regulate a person's BP. Such a fall in BP with standing is called postural hypotension (low blood pressure), which, when significant, can cause weakness, lightheadedness, and even fainting. The treatment of high blood pressure (hypertension) with medications in these patients may actually lead to an excessive fall in BP with standing.
