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 can be mild. Episodes might be brief.
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.
Neurogenic orthostatic hypotension is caused by an intrinsic failure of the autonomic nervous system to create a normal physiologic response (baroreflex dysfunction).
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.
Some causes of orthostatic hypotension are permanent, such as Parkinson disease, while others are transient, such as anemia which can be corrected. Providers should address reversible causes, such as infection, drugs, dehydration, and anemia.
Find out what you need to know about orthostatic hypotension — the sudden drop in blood pressure when you stand up that can make you feel faint.
A drop of 20 millimeters of mercury (mm Hg) in the top number (systolic blood pressure) within 2 to 5 minutes of standing is a sign of orthostatic hypotension. A drop of 10 mm Hg in the bottom number (diastolic blood pressure) within 2 to 5 minutes of standing also indicates orthostatic hypotension. Blood tests.
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.
Treatment |. Geriatrics Essentials |. Key Points |. More Information. Orthostatic (postural) hypotension is an excessive fall in blood pressure (BP) when an upright position is assumed. The consensus definition is a drop of > 20 mm Hg systolic, > 10 mm Hg diastolic, or both (1).
Postural hypotension is more common in older adults and may be caused by volume depletion (e.g., dehydration), certain medications, and an underlying nervous system condition. This article explores what it means to have postural hypotension, including its symptoms, causes, diagnosis, and treatment.

Standing blood pressure can often be increased sufficiently to improve orthostatic tolerance by removing or reducing factors that trigger or exacerbate orthostatic hypotension, such as hypovolaemia and medications, or by preventing physical deconditioning.

Mayo Clinic has one of the largest and most experienced practices in the United States, with campuses in Arizona, Florida and Minnesota. Staff skilled in dozens of specialties work together to ensure quality care and successful recovery.
The numerous possible causes for orthostatic hypotension include certain medications (e.g. alpha blockers), autonomic neuropathy, decreased blood volume, multiple system atrophy, and age-related blood-vessel stiffness.
Causes. Loss of fluid within the blood vessels is the most common cause of symptoms linked to orthostatic hypotension. This could be due to dehydration brought about by diarrhea, vomiting, and...
Orthostatic hypotension (OH), a common, often overlooked, disorder with many causes, is associated with debilitating symptoms, falls, syncope, cognitive impairment, and risk of death.
Orthostatic hypotension (OH) describes a reduction in systolic blood pressure of at least 20 mmHg or a reduction in diastolic blood pressure of at least 10 mmHg, usually within the first three minutes of standing or head-up tilt on a tilt table.
Orthostatic hypotension is a type of low blood pressure that occurs when moving from a sitting position to a standing position. Learn the causes, symptoms, diagnosis, tests, treatment, and complications of orthostatic hypotension.
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.
Medication side effects or not getting enough water are some common causes. This can also happen in people with diabetes, Parkinson disease, or a nervous system disorder. What should I...
There are many possible causes of orthostatic hypotension, including prolonged bed rest, pregnancy, dehydration, diabetes, heart problems, excessive heat, burns, large varicose veins, and some brain disorders.
There are many causes of OH. Aging coupled with diseases such as diabetes and Parkinson's disease results in a prevalence of 10-30% in the elderly. These conditions cause baroreflex failure with resulting combination of OH, supine hypertension, and loss of diurnal variation of BP.
Orthostatic hypotension (OH) is a common non-motor feature of Parkinson’s disease that may cause unexplained falls, syncope, lightheadedness, cognitive impairment, dyspnea, fatigue, blurred vision, shoulder, neck, or low-back pain upon standing. Blood pressure (BP) measurements supine and after 3 minutes upon standing screen for OH at bedside.
Disorders characterized by orthostatic intolerance besides POTS include: i) orthostatic hypotension – a disorder defined by a sustained reduction of systolic blood pressure of at least 20 mmHg or diastolic blood pressure of 10 mmHg, with or without symptoms during the assessment, within three minutes of standing. ... Secondary causes include ...
