How to tell if you have orthostatic hypotension?
Orthostatic hypotension is generally evaluated by measuring the blood pressure of a patient while sitting, or lying down, and again while standing. Currently, a person whose blood pressure drops more than 20 mm Hg in systolic pressure (the top number) or more than 10 mm Hg in diastolic pressure (the bottom number) is considered to have orthostatic hypotension. A new research study suggests a more accurate way to diagnose orthostatic hypotension is using a calculation called “upright mean arterial blood pressure,” which takes into account both the systolic and diastolic blood pressures. When this number is under 75 mm Hg, it indicates orthostatic hypotension. 1
What is the name of the drop in blood pressure that happens when you stand up?
Symptoms - Orthostatic Hypotension. Orthostatic hypotension is a severe drop in blood pressure that happens when the person stands up from sitting or lying down. Orthostatic hypotension may cause dizziness or a loss of consciousness, causing the person to faint or pass out.
What is the blood pressure of a person with orthostatic hypotension?
Currently, a person whose blood pressure drops more than 20 mm Hg in systolic pressure (the top number) or more than 10 mm Hg in diastolic pressure (the bottom number) is considered to have orthostatic hypotension.

INTRODUCTION
Orthostatic hypotension (OH) may affect every third patient with Parkinson’s disease throughout the disease course [ 1–5 ].
FIRST STEP: MAKE THE RIGHT DIAGNOSIS
Given its unspecific, and sometimes asymptomatic, presentation, OH should be actively screened at bedside by measuring the BP and heart rate (HR) supine and after 3 minutes upon standing [ 19 ]. OH is diagnosed in case of a systolic BP fall ≥20 mmHg and/or diastolic ≥10 mmHg with respect to baseline [ 20 ].
TREATMENT OF OH
If the clinical assessment pinpoints dehydration, severe anemia or infections, these should be treated first.
TREATMENT OF POST-PRANDIAL HYPOTENSION
Conservative measures to treat postprandial hypotension include alcohol abstinence and fractionating meals.
TREATMENT OF SUPINE AND NOCTURNAL HYPERTENSION
Simple behavioral measures may prevent patients with neurogenic OH from developing overt SH [ 52 ]:
FUTURE PERSPECTIVES
Despite combined treatment strategies, the symptomatic burden of OH remains high in a significant proportion of patients with PD and BP fluctuations due to concomitant SH represent a management challenge. This highlights the need for new therapeutic and safety studies in PD.

What is neurogenic orthostatic hypotension?
Stuart H Isaacson, Julia Skettini#N#Parkinson's Disease and Movement Disorders Center of Boca Raton, Boca Raton, FL, USA#N#Abstract: Neurogenic orthostatic hypotension (nOH) is due to failure of the autonomic nervous system to regulate blood pressure in response to postural changes due to an inadequate release of norepinephrine, leading to ortho static hypotension and supine hypertension. nOH is common in Parkinson's disease (PD). Prevalence varies throughout the course of PD, ranging from 40% to 60%, and resulting in symptomatic nOH in approximately half. Symptomatic nOH, including lightheadedness, can limit daily activities and lead to falls. Symptomatic nOH can also limit therapeutic options for treating PD motor symptoms. Clinical evaluation should routinely include symptom assessment and blood pressure measurement of supine, sitting, and 3-minute standing; 24-hour ambulatory blood pressure monitoring can also be helpful. Non-pharmacological management of symptomatic nOH involves education, physical maneuvers, and adequate hydration. Current pharmacological treatment of symptomatic nOH includes salt supplement, fludrocortisone, midodrine, pyridostigmine, and other empiric medications. Despite these options, treatment of symptomatic nOH remains suboptimal, often limited by severe increases in supine blood pressure. Droxidopa, an oral prodrug converted by decarboxylation to norepinephrine, is a promising therapeutic option for symptomatic nOH in PD, improving symptoms of nOH, daily activities, falls, and standing systolic blood pressure in several recent trials. These trials demonstrated short-term efficacy and tolerability, with comparable increases in standing and supine blood pressures. Longer-term studies are ongoing to confirm durability of treatment effect.#N#Keywords: (pre)syncope, norepinephrine, autonomic, lightheadedness, treatment, falls
What causes blood pressure to drop when standing?
In patients with PD and nOH, autonomic dysfunction causes blood pressure to fall upon standing, due to an inappropriate NE response to postural change. Orthostatic hypotension has been defined as a drop in SBP of at least 20 mmHg or a drop in diastolic blood pressure of at least 10 mmHg after 3 minutes of standing. 9 There is often a loss of the cardioacceleratory response too. 10 Non-neurogenic causes of orthostatic hypotension are also common in patients with PD, and contribute to blood pressure drop. 11 These non-neurogenic causes of orthostatic hypotension should be identified first, and include dehydration, medications, and cardiac pump failure. A clinical diagnosis of nOH can be made when these non-neurogenic causes of persistent orthostatic hypotension are excluded, and can be confirmed through autonomic testing and plasma NE levels. 12
How do you know if you have orthostatic hypotension?
The most common symptoms of orthostatic hypotension are dizziness and lightheadedness upon standing up. The symptoms will usually go away when sitting or lying down.

Overview
- Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make you feel dizzy or lightheaded, and maybe even faint.Orthostatic hypotension may be mild and last for less than a few minutes. However, long-lasting orthostatic hypotension can signal more-serious prob…
Treatment
- Acute orthostatic hypotension generally resolves with treatment of the underlying cause. In patients with chronic orthostatic hypotension, pharmacologic and nonpharmacologic treatments may be beneficial. All patients with chronic orthostatic hypotension should be educated about their diagnosis and goals of treatment, which include improving orthostatic blood pressure with…
- The goal of treatment for orthostatic hypotension is to restore normal blood pressure. That usually involves increasing blood volume, reducing the pooling of blood in your lower legs and helping blood vessels to push blood throughout your body.Treatment often addresses the underlying cause — dehydration or heart failure, for example — rather than the low blood pressur…
- Primary care practitioner (internist); or in complicated cases (severe orthostatic hypotension) a neurologist is consulted.

- It is important that the clinician take numerous blood pressure measurements on different occasions, since blood pressure can vary (i.e. postural hypotension, another disorder causing hypotension, is often worse in the morning when rising from bed). A detailed history and physical examination is important. The clinician should focus medical evaluation on autonomic symptom…
Causes
- When you stand up, gravity causes blood to pool in your legs and abdomen. This decreases blood pressure because there's less blood circulating back to your heart.Normally, special cells (baroreceptors) near your heart and neck arteries sense this lower blood pressure. The baroreceptors send signals to centers in your brain, which signals your heart to beat faster and p…
- Orthostatic hypotension can be caused by several different disorders that affect the entire body (systemic disorders), the central nervous system (CNS, consisting of the brain and spinal cord), and the autonomic nervous system (peripheral autonomic neuropathy) or as a result of taking certain medications that are commonly prescribed by clinicians. Systemic causes can include d…
Definition
- Orthostatic hypotension is defined as a decrease in systolic blood pressure of 20 mm Hg or a decrease in diastolic blood pressure of 10 mm Hg within three minutes of standing when compared with blood pressure from the sitting or supine position. It results from an inadequate physiologic response to postural changes in blood pressure. Orthostatic hypotension may be ac…
- Orthostatic hypotension (OH) is defined as a sudden drop in blood pressure upon standing from a sitting or supine position. It is also known as postural hypotension. Diagnosis is made if the blood pressure drops by or greater 20mmHg systolically and 10mmHg diastolically. This occurs within three minutes of standing after being supine for 5 minutes or at 60% angle on a tilt table. This su…
- Orthostatic hypotension refers to a reduction of blood pressure (systolic blood pressure that occurs when the heart contracts) of at lest 20 mmHg or a diastolic pressure (pressure when the heart muscle relaxes) of at least 10 mmHg within three minutes of standing.
Management
- Treatment strategies for autonomic disorders include the following: 1. AAN: Treatment is based on anecdotal evidence 2. Chronic PAF syndromes: Treatment is symptomatic only 3. POTS: Can be treated with low doses of beta blockers, as patients are normally sensitive to their adverse effects Nonpharmacologic measures are useful for all patients with autonomic dysfunction. The…
Mechanism
- A normal hemodynamic response to changes in posture requires normal function of the cardiovascular and autonomic nervous systems. Standing results in blood pooling of approximately 500 to 1,000 mL in the lower extremities and splanchnic circulation. This initiates an increase in sympathetic outflow, which increases peripheral vascular resistance, venous retur…
Risk Factors
- The risk factors for orthostatic hypotension include: 1. Age. Orthostatic hypotension is common in those who are age 65 and older. Special cells (baroreceptors) near your heart and neck arteries that regulate blood pressure can slow as you age. It also may be harder for an aging heart to beat faster and compensate for drops in blood pressure. 2. Medications. These include medications …
Complications
- Persistent orthostatic hypotension can cause serious complications, especially in older adults. These include: 1. Falls. Falling down as a result of fainting (syncope) is a common complication in people with orthostatic hypotension. 2. Stroke. The swings in blood pressure when you stand and sit as a result of orthostatic hypotension can be a risk factor for stroke due to the reduced bloo…
