Orthostatic hypotension is a persistent decrease of systolic blood pressure by at least 20 mm Hg and/or diastolic blood pressure by at least 10 mm Hg in the first 3 minutes upon standing. Orthostatic hypotension is more common in the elderly patients, being one of relatively frequent causes of hospitalization in the elderly population. Orthostatic hypotension may be primary or secondary, acute or chronic. Its etiology is represented in most cases by the primary or secondary autonomic failure. Clinical manifestations of orthostatic hypotension occur after the transition from supine to standing, and are due to cerebral hypoperfusion. These consist of nausea, dizziness, generalized weakness, postural instability, fatigue, blurred vision. Cardiological and neurological consult are necessary for diagnosis. Pharmacological treatment of orthostatic hypotension is often unsatisfactory, imposing combination with non-pharmacological measures.
