Abstract
Blood pressure homeostasis is particularly challenged by moving to an upright position. The autonomic nervous system, structural factors, infravascular volume, and circulating and local hormones influence the body's response to a change in posture. Disorders of the autonomic nervous system can result in orthostatic hypotension. Both neurogenic and nonneurogenic disorders can contribute, and distinguishing between the two causes is important for both diagnosis and management. It is also important to recognize various factors in daily life that influence orthostatic hypotension.
