Orthostatic hypotension: An overlooked but clinically decisive entity

ABSTRACT

Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP. Its clinical manifestation can range from dizziness to syncope. It is a common cause of recurrent falls and fracture in older adults. Its etiology ranges from neurological causes such as Parkinson and diabetes to hypovolemia. Drugs, especially cardiovascular drugs are also frequently identified as the cause of OH. The management of OH is primarily nonpharmacological including medication review, dietary, and lifestyle modifications. However, in partially responsive or resistant cases, medications such as fludrocortisone, midodrine, droxidopa, etc., are also used.
