Misconceptions and Facts About Orthostatic Hypotension.

Orthostatic hypotension is a highly prevalent medical condition that is an independent risk factor for falls and mortality. It reflects a condition in which autonomic reflexes are impaired or intravascular volume is depleted, causing a significant reduction in blood pressure upon standing. This disorder is frequently unrecognized until later in its clinical course. Symptoms like orthostatic dizziness do not reliably identify patients with orthostatic hypotension, who are often asymptomatic, leading further to the difficulty of this diagnosis. We summarize seven clinically important misconceptions about orthostatic hypotension.
