==Background==
* More common in older patients
* Symptomatic orthostasis is clinically much more important than actual change in vitals
** Classically, drop in SBP ≥20 mm Hg or increase in HR ≥ 30 bpm when moving from lying to standing
** Studies show that orthostatic vitals common at baseline health, and not necessarily abnormal in moderate volume loss <ref>Ooi WL, Barrett S, Hossain M, Kelley-Gagnon M, Lipsitz LA.

==Clinical Features==
* Sudden postural changes resulting in cerebral hypoperfusion
* [[Weakness]], lightheadedness, visual blurring
* Occasionally, [[syncope]]

==Differential Diagnosis==
* Autonomic dysfunction
** [[Parkinson's disease]]
** [[Lewy Body Dementia]]
** Shy-Drager Syndrome
** [[Diabetes]]
* Aging
* [[hypovolemia|Volume depletion]]
** [[Diuretics]]
** [[Hemorrhage]]
** [[Vomiting]]/ [[Diarrhea]]
* Medications
** [[Antihypertensives]], antiparkinsonism, [[beta blockers]], vasodilatory drugs
* Alcohol use
* [[Syncope]]
* [[Seizure]]
* Postural tachycardia syndrome (POTS)

==Evaluation==
* Review medication list
* History of potential volume loss
* CBC (anemia)
* BMP (electrolytes, BUN, Cr, glucose)
* [[EKG]] 

==Management==
* Address the underlying cause
** [[Fluids]], blood [[transfusion]] when appropriate
** Consider discontinuing at risk medications

==Disposition==
Depends on patient's risk, etiology of orthostasis, secondary complications such as worsening hypovolemia, potential for falls
