orthostatic hypotension
Quick Summary
Orthostatic hypotension is a medical condition characterized by a sudden drop in blood pressure when a person stands up from a sitting or lying position. This occurs due to a failure in the autonomic nervous system, which normally constricts blood vessels to counteract gravity when standing. When this reflex is impaired, blood pools in the legs, leading to a temporary decrease in blood flow to the brain.12
This can cause symptoms such as dizziness, lightheadedness, fainting (syncope), and blurred vision. Causes can include dehydration, certain medications, extensive bleeding or burns, and diseases affecting the autonomic nervous system.12
