Hypotension
In physiology and medicine, hypotension refers to an abnormally low blood pressure. It is often associated with shock, though not necessarily indicative of it.

Orthostatic hypotension is a common cause of low blood pressure, resulting from a sudden change in body position. Reduced blood volume, called hypovolemia, can also cause hypotension and often results from the use of diuretics or vasodilators such as nitric oxide or furosemide.
