Dizzy when standing up? Orthostatic hypotension, also called postural hypotension, is a drop in blood pressure when you stand. Learn what it is, its symptoms, and the difference between its two main forms: neurogenic and non-neurogenic. This short Rehealthify explainer shows how the nervous system normally helps maintain blood flow to the brain when you stand—and why that adjustment can fail. It also covers contributing factors, including dehydration, certain heart conditions, medications, and alcohol, plus why older adults are more susceptible. Sometimes, no clear cause is identified.
