suspected. Orthostatic hypotension (also known as postural hypotension
, and, colloquially, as head rush or a dizzy spell and to some people "the elevator effect") is a form of hypotension in which a person's blood pressure suddenly falls when the person stands up. The decrease is typically greater than 20/10 mm Hg, and may be most pronounced after resting.
The incidence increases with age.(Wikipedia)
Orthostatic (postural) hypotension is an excessive fall in BP when an upright position is assumed. The consensus definition is a drop of > 20 mm Hg systolic, 10 mm Hg diastolic, or both. Symptoms of faintness, light-headedness, dizziness
, confusion, or blurred vision
occur within seconds to a few minutes of standing and resolve rapidly on lying down. Some patients experience falls, syncope
or even generalized seizures. Exercise or a heavy meal may exacerbate symptoms. Most other associated symptoms and signs relate to the cause. Orthostatic hypotension is a manifestation of abnormal BP regulation due to various conditions, not a specific disorder.(Merck)
