Orthostatic hypotension is more common in the elderly than in younger patients. Its underlying cause is a failure of the autonomic nervous system to appropriately vasoconstrict the peripheral vasculature in response to standing. Orthostatic hypotension may be caused by diseases that disrupt the autonomic nervous system, such as Parkinson disease, diabetes, amyloidosis, or familial dysautonomia. Orthostatic hypotension is also a common side effect of certain medications, such as antihypertensives and diuretics.
Orthostatic hypotension can be treated with lifestyle modifications and medications that increase vasoconstriction or intravascular volume.
