orthostatic hypotension, postural hypotension(noun)
low blood pressure occurring in some people when they stand up
Orthostatic hypotension, also known as postural hypotension, orthostasis, and colloquially as head rush or dizzy spell, is a form of hypotension in which a person's blood pressure suddenly falls when standing up or stretching. Medically it is defined as a fall in systolic blood pressure of at least 20mm Hg and diastolic blood pressure of at least 10 mm Hg when a person assumes a standing position. The symptom is caused by blood pooling in the lower extremities upon a change in body position. It is quite common and can occur briefly in anyone, although it is particularly prevalent among the elderly, and those with low blood pressure.
