Background
- More common in older patients
- Symptomatic orthostasis is clinically much more important than actual change in vitals
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
- Volume depletion
- 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
