Orthostatic hypotension: pathophysiology, assessment, treatment and the paradox of supine hypertension

Both hypertension and orthostatic hypotension ( OH ) are strongly age‐associated and are common management problems in older people. However, unlike hypertension, management of OH has unique challenges with few well‐established treatments. Not infrequently, they both coexist, further compounding the management. This review provides comprehensive information on OH , including pathophysiology, diagnostic workup and treatment, with a view to provide a practical guide to its management. Special references are made to patients with supine hypertension and postprandial hypotension and older hypertensive patients.
