Blood pressure is measured in millimeters of mercury (mmHg) and has two figures:
What is orthostatic hypotension?
Orthostatic hypotension is defined as a sudden drop in blood pressure upon standing from a sitting or supine position. Clinically, this is diagnosed by a sustained reduction in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of 10 mmHg within three minutes of standing after being supine for five minutes or at a 60-degree angle on the tilt table. This sudden drop in blood pressure is usually secondary to failure of autonomic reflex, volume depletion, or adverse reaction to medication. Symptoms on presentation are commonly related to cerebral hypoperfusion, but patients can also be asymptomatic. There also is a high rate of morbidity and mortality related to this disease process due to frequent falls, which can lead to multiple hospital admissions. [1][2][3][4][5]
How long to stand for orthostatic blood pressure?
After five minutes of lying supine, the patient should be asked to stand quietly for two to five minutes, and vital signs should be taken again. If there is a 20 mmHg drop in systolic blood pressure or a 10 mmHg drop in diastolic blood pressure, one can make the diagnosis of orthostatic hypotension. [6][7][8][9]
What happens when you stand up from a supine position?
This results in decreased venous return to the heart, and as a result, there is a decrease in cardiac output as defined by the Frank Starling Curve. The human body normally compensates with an increase in sympathetic tone and a decrease in vagal tone, known as the baroreceptor reflex. This increase in sympathetic outflow raises peripheral vascular resistance, which subsequently increases venous return and cardiac output, thereby limiting the fall in blood pressure. When patients lack this compensatory mechanism, they present with symptoms of orthostatic hypotension.
Is orthostatic hypotension neurogenic?
Orthostatic hypotension can be caused by both neurogenic and non-neurogenic etiologies and can also be related to medication. Neurogenic orthostatic hypotension is characterized by autonomic instability secondary to neuropathic disease, neurodegenerative disease, or aging. Neuropathic diseases include diabetes, cholinergic receptor autoantibodies, and familial dysautonomia. Neurodegenerative diseases include Parkinson disease, multiple-system atrophy, and pure autonomic failure. Non-neurogenic orthostatic hypotension is most commonly due to volume depletion. One must also consider medication induced orthostatic hypotension particularly in the case of polypharmacy in the elderly.
Can orthostatic hypotension cause supine hypertension?
Approximately 50% of patients with neurogenic orthostatic hypotension suffer from supine hypertension. This association is due to side effects from anti-hypertensive medications as well as the common autonomic dysfunction seen in these patients due to comorbid conditions, such as diabetes mellitus. There is currently no approved anti-hypertensive medication that selectively targets the supine position. This complicates treatment because supine hypertension in patients with autonomic failure can result in end organ damage. The treatment approach for these patients is currently being studied and might be an outlet for individualized based medicine in the future.

What is orthostatic hypotension?
When a person stands up from sitting or lying down, the body must work to adjust to that change in position. It is especially important for the body to push blood upward and supply the brain with oxygen. If the body fails to do this adequately, blood pressure falls, and a person may feel lightheaded or even pass out.
What are the symptoms of orthostatic hypotension?
When the brain does not get enough blood supply, it begins to shut down.
What are the risk factors for orthostatic hypotension?
Orthostatic hypotension most often occurs in the elderly. "Hardening of the arteries" or atherosclerosis that develops as we age makes it more difficult for blood vessels to adapt quickly when necessary. As well, many of the diseases that are associated with orthostatic hypotension are progressive, with symptoms worsening with age.
What causes orthostatic hypotension?
Orthostatic hypotension has many potential causes, some affecting only one part of the system that supplies blood to the brain, and others affecting two or three.
When should I call the doctor for orthostatic hypotension?
Feeling faint or lightheaded is not normal. While a rare episode that can be explained by circumstances, such as working or exercising in the heat, may be ignored, more frequent occurrences should be investigated.
How is orthostatic hypotension diagnosed?
The key to the diagnosis is a good history and physical examination. The health care practitioner will want to know the circumstances that are associated with the symptoms of lightheadedness or passing out, since the patient is unlikely to have taken their blood pressure and checked their pulse rate in the midst of the episode.
What are the causes of orthostatic hypotension?
the reasons for orthostatic hypotension, in this case, lie in the violation of the regulation of vascular tone at the highest level: the “orders” are given by the nervous system, which is not at all in good condition to command. Similar phenomena occur in diabetes and hypothyroidism.
Why is orthostatic hypotension possible?
This is possible due to hemodynamic disturbances in various pathologies, both cardiac and extracardiac origin (orthostasis is the vertical position of the body).

Common triggers of this severe and potentially life-threatening reaction include foods, certain medications, insect venoms and latex.
Why does blood pool in legs?
Gravity causes blood to pool in your legs when you stand. Ordinarily, your body compensates by increasing your heart rate and constricting blood vessels, there by ensuring that enough blood returns to your brain.
Why does blood pressure drop during pregnancy?
Pregnancy. Because the circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. This is normal, and blood pressure usually returns to your pre-pregnancy level after you've given birth.
Why is it important to see a doctor for low blood pressure?
Still, it's important to see your doctor if you have signs or symptoms of low blood pressure because they can point to more-serious problems. It can be helpful to keep a record of your symptoms, when they occur and what you're doing at the time.
Can ACE inhibitors cause orthostatic hypotension?
