Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when standing after sitting or lying down. Orthostatic hypotension can cause dizziness or lightheadedness and possibly fainting.
Orthostatic hypotension is a condition described by a significant reduction in blood pressure that typically occurs upon standing or assuming an upright posture. It may be asymptomatic or symptomatic and can be due to impaired autonomic reflexes or intravascular volume depletion.
Orthostatic hypotension causes may include: Your heart can’t pump as much blood as it should. Your autonomic nervous system (which usually brings your blood pressure back to normal) isn’t working right. You have Parkinson disease, Lewy body dementia or multiple system atrophy.
Orthostatic hypotension can be caused by both neurogenic and non-neurogenic etiologies and can also be related to medications. Neurogenic orthostatic hypotension is characterized by autonomic instability secondary to neuropathic disease, neurodegenerative disease, or aging.
Orthostatic hypotension, also called postural hypotension, is a sudden drop in blood pressure that occurs when you stand up quickly. “Orthostasis” means “to stand up,” “ hypotension ” is...
A health care provider's goal in evaluating orthostatic hypotension is to find the cause and determine treatment. The cause isn't always known. A care provider might review medical history, medications and symptoms and conduct a physical exam to help diagnose the condition.
Orthostatic hypotension, also called postural hypotension. This is a sudden drop in blood pressure when standing up after sitting or lying down. Causes include dehydration, long-term bed rest, pregnancy, certain medical conditions and some medicines.
Orthostatic hypotension or postural hypotension can make you feel lightheaded or dizzy when standing up. Here's what causes it and how to manage it.
Common causes include drugs (e.g., alpha-blockers, including tamsulosin [used for treating conditions such as benign prostatic hypertrophy], central sympatholytics, including tizanidine [used as a muscle relaxant], and diuretics), diseases causing peripheral neuropathy (e.g., diabetes mellitus), Parkinson's disease, and dementia with Lewy bodies.
Orthostatic hypotension is a manifestation of abnormal BP regulation due to various conditions, not a specific disorder. Evidence suggests that disorders of postural hemodynamic control increase risk of cardiovascular disease and all-cause mortality (2, 3).
