Hypotension: Causes & Reasons

Possible Causes for Hypotension

Orthostatic hypotension is otherwise known as postural hypotension, since a change of posture is responsible for the sudden-onset episode of decreased blood pressure. [symptoma.com]

Orthostatic hypotension may be acute or chronic. [aafp.org]
