Diagnosis Of Orthostatic Hypotension
- Medical history, including medical conditions and drugs taken on a regular basis
- Physical examination
- Measuring blood pressure when lying down versus standing up
- Blood tests to check, for example, blood sugars or adrenal hormones
- Echocardiography, an imaging scan of the heart, to check for certain heart conditions
- Other tests, depending on individual factors.
Why Does Bp Drop When You Stand Up
Orthostatic hypotension is a symptom of reduced or inefficient autonomic inactivity which involves both sympathetic and parasympathetic nervous systems. In the symptom there is a fall in blood pressure when the person changes its posture from one position to another especially when the person is lying down and stands abruptly, it is seen the most.
The mechanism working behind static hypertension is the venous pooling of the blood. When the autonomic activity of the nerve gets affected, it reduces the innervation to the muscles of the blood vessels. The blood vessels especially veins get affected because they have lesser muscle tissue and the tone maintenance is very important. This leads to a collection of blood in the venous system of the body especially in the lower part of the body and the tone is inefficient to pump it back in the heart especially in standing position.
When the person is lying down the whole blood vessels of the body are at the same level and there is no venous pooling but when the same person stands, there is the effect of gravity working upon the blood in the veins of legs. It leads to a downward force on the blood due to its weight and it gets collected in the lower veins. There is an insufficient amount of blood reaching the right atrium of the heart, which leads to inefficient pumping of blood from the heart and ultimately leading to a falling in the blood pressure.
Old Age Is An Important Risk Factor
- Digestion when you eat and then digest food, an increased blood supply is sent to your intestines. Orthostatic hypotension is more likely to occur about 15 to 45 minutes after eating a meal .
- Standing if you stand up for a long time, it causes a slow but steady drop in blood pressure.
- Frailty and chronic sickness these are more common in old age.

Patients Whose Blood Pressure Changed The Most Over Time Were At Even Higher Risk For Dementia
But it wasnt just the initial diagnosis or reading that showed a higher risk of dementia. The researchers also divided the participants into groups based on how much their blood pressure readings changed throughout the study. They found that 24 percent of patients in the group with the most changes in systolic blood pressure later developed dementia, compared to 19 percent of patients with less change over time. When adjusted for risk factors, the group with more change was 35 percent more likely to develop dementia than those with less change.

Known As Orthostatic Hypotension This Condition Can Leave People Dizzy And Lightheaded For Some It May Also Be A Harbinger Of Heart Disease
Have you ever felt a bit woozy just after standing up? When you transition from sitting to standing, gravity causes blood to pool in your legs. Sometimes especially if you’re dehydrated or overheated it takes your body a moment to push blood upward, causing a brief delay in blood flow to the brain.
For most people, this phenomenon occurs just once in a while and usually isn’t a serious problem. But age, some medications, and certain medical conditions can interfere with the body’s normal mechanism for regulating blood pressure . If that happens, your blood pressure may drop dramatically when you stand up. Known as orthostatic hypotension , the problem affects about 5% of people younger than 50. But up to 20% of people ages 70 and older may have OH.
Several diseases, including diabetes, Parkinson’s disease, and cancer, can contribute to the problem, which is also known as postural hypotension. Now, new research adds to the suspected connection between OH and cardiovascular disease.
When Should I Talk To My Doctor
Feeling dizzy when you stand every once in a while is probably no cause for concern. But if you have the symptoms of orthostatic hypotension often, you should bring it up with your doctor so they can figure out whatâs causing it. Before your appointment, keep a record of your symptoms, when they happen, and how long they last. If you fall during one of your dizzy spells, or have any of the following symptoms of heart failure, you should get medical help ASAP:

What Are The Symptoms Of Orthostatic Hypotension
Orthostatic hypotension happens more frequently and with more severe symptoms in the mornings. Thats because blood pressure is at its lowest in the morning.
Some people dont experience any symptoms from orthostatic hypotension. Others find that hot temperatures make symptoms worse.
The main sign of orthostatic hypotension is dizziness or lightheadedness when you stand. You should feel better when you sit or lie down. Some people faint .
Other signs include:
Active Stand Test For Pots
If you have an active stand test, youll usually be asked to lie flat for a few minutes and then your heart rate and blood pressure will be measured. Youll then be asked to stand up and your heart rate and blood pressure will be measured a few more times over the next 10 minutes.
- 24-hour ECG and/or blood pressure monitoring

Postural Orthostatic Tachycardia Syndrome
Postural orthostatic tachycardia syndrome is a blood circulation disorder characterized by two factors:
A specific group of symptoms that frequently occur when standing upright
A heart rate increase from horizontal to standing of at least 30 beats per minute in adults, or at least 40 beats per minute in adolescents, measured during the first 10 minutes of standing
POTS is diagnosed only when orthostatic hypotension is ruled out and when there is no acute dehydration or blood loss. Orthostatic hypotension is a form of low blood pressure: 20mm Hg drop in systolic or a 10mm Hg drop in diastolic blood pressure in the first three minutes of standing upright.
If You Notice A Sudden Decline In Blood Pressure
A single lower-than-normal reading is not cause for alarm, unless you are experiencing any other symptoms or problems. If you experience any dizziness, lightheadedness, nausea or other symptoms, its a good idea to consult with your healthcare provider. To help with your diagnosis, keep a record of your symptoms and activities at the time they occurred.

What Is The Best Position For Measuring Blood Pressure
The American Heart Association recommends sitting down to take your blood pressure. They also note that while there are differences in the right arm versus the left arm, these are small and only cause a variation of 10 mm Hg or less.
Additional posture-related factors can also affect your blood pressure readings. To get an accurate reading at your doctors office try to:
- Sit up straight, with your back supported by the back of your chair.
- Make sure your feet are flat on the floor. Avoid crossing your legs or ankles.
- Place your arm at the level of your heart, supporting it on a table or armrest. You may need to use a pillow to help get the right elevation.
There are some instances where you may have your blood pressure taken lying down. An example of this is if youve been hospitalized and cant sit up.
If you have orthostatic hypotension, your blood pressure may be taken in two different positions sitting and standing. This can help your doctor monitor how your blood pressure changes when you move from a sitting to a standing position.
What Is Low Blood Pressure
Hypotension is the medical term for low blood pressure .
A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood. The second number measures diastolic pressure, or the pressure in the arteries when the heart rests between beats.
Optimal blood pressure is less than 120/80 . In healthy people, low blood pressure without any symptoms is not usually a concern and does not need to be treated. But low blood pressure can be a sign of an underlying problem — especially in the elderly — where it may cause inadequate blood flow to the heart, brain, and other vital organs.
Chronic low blood pressure with no symptoms is almost never serious. But health problems can occur when blood pressure drops suddenly and the brain is deprived of an adequate blood supply. This can lead to dizziness or lightheadedness. Sudden drops in blood pressure most commonly occur in someone who’s rising from a lying down or sitting position to standing. This kind of low blood pressure is known as postural hypotension or orthostatic hypotension. Another type of low blood pressure can occur when someone stands for a long period of time. This is called neurally mediated hypotension.

Condition Causes Significant Drop In Blood Pressure Upon Standing
Dear Mayo Clinic:
My mother is 62 and has had very low blood pressure for two years. She was hospitalized with blood pressure that dropped from 200/78 in bed to 60/40 sitting up. What could be causing this and what can be done to treat her?
Your mother has a condition called orthostatic hypotension. It happens when blood pressure falls significantly as a person stands up. Orthostatic hypotension can cause a variety of symptoms the most common are feelings of dizziness and faintness.
Blood pressure is a measure of the pressure in a person’s arteries during the active and resting phases of each heartbeat. When you stand, gravity causes your blood pressure to fall slightly as blood pools in your legs, lowering the amount of blood circulating back to your heart to pump. Normally, the drop in blood pressure is limited, though, because when you stand your nervous system triggers your blood vessels to narrow and your heart to beat faster. Sometimes, however, those nervous system responses do not happen the way they should, resulting in large swings in blood pressure from lying down to standing.
Symptoms of orthostatic hypotension usually get worse in hot weather or when you are dehydrated. Some medications can also increase symptoms of orthostatic hypotension, including blood pressure medications, medications used to treat Parkinson’s disease, antidepressants and bronchodilators, as well as caffeine, alcohol and appetite suppressants.
Increase In Heart Rate As Blood Pressure Falls Could Be Early Sign Of Neurological Disease
- NYU Langone Health / NYU School of Medicine
- A simple bedside test that matches a change in heart rate with a drop in blood pressure after a patient stands may help doctors diagnose certain degenerative brain diseases, according to a new study.
A simple bedside test that matches a change in heart rate with a drop in blood pressure after a patient stands may help doctors diagnose certain degenerative brain diseases. This is the finding of a study led by neurologists at NYU School of Medicine and published in the March issue of Annals of Neurology.
The test could enable earlier diagnosis of a group of degenerative brain diseases called synucleinopathies, which include Parkinson’s disease, Lewy Body dementia, and multiple system atrophy. Arising from the abnormal buildup of a protein known as alpha-synuclein in the brain, such conditions damage the nerves that control blood pressure and heart rate.
Falling blood pressure after standing, a condition known as orthostatic hypotension, can cause dizziness, lightheadedness and fainting. When orthostatic hypotension is due to impaired activation of nerves that squeeze the blood vessels, the condition is called “neurogenic orthostatic hypotension,” and is a hallmark feature of failure of the autonomic nervous system. This system regulates bodily functions such as heart rate, breathing, and metabolism.

How Is Orthostatic Hypotension Diagnosed
Your healthcare provider will check your blood pressure while youre seated, lying down and standing. You may also get one or more of these tests:
- Blood tests to check for conditions like diabetes and anemia.
- Echocardiogram to check the hearts pumping action.
- Electrocardiogram to test for heart rhythm changes.
- Exercise stress test to measure heart rate during physical exertion.
- Portable EKG devices to measure heart rhythm.
- Tilt table test to safely measure blood pressure, heart rate and heart rhythm while you lie on a table that moves from horizontal to vertical.
Lifestyle Changes For Pots
Very often, lifestyle changes, centred on diet, exercise and changing some of your daily habits, are enough to improve any POTS symptoms you may have. The most commonly recommended changes include:
- drinking plenty of fluids aim for your pee to be a light yellow colour
- avoiding or cutting down on alcohol and caffeine these can make your symptoms worse
- adding more salt to your diet only do this if a doctor tells you to. Extra salt may be harmful to people with some conditions, like kidney disease and heart disease
- wearing compression stockings wear these up to your waist to help keep your blood circulating well
- raising the head end of your bed, so you arent lying flat when you sleep
- not standing or sitting for long periods of time
- standing up slowly after sitting or lying down
- exercising often but take care to avoid overdoing things as this can make your symptoms worse. Stick to light or moderate exercise, and increase how much you do slowly. Read more about how much physical activity you need to stay healthy
Some people notice that certain factors, like eating, doing a lot of exercise, feeling hot, being dehydrated or drinking alcohol, make their symptoms worse. If this is true for you, avoiding these triggers may also help to reduce your symptoms.

Postural Orthostatic Tachycardia Syndrome Diet
The foundation of treating POTS is to drink fluids frequently throughout the day. For most POTS patients, the goal is at least 64-80 ounces a day. You would also need to increase your intake of salty foods and add more salt to your diet with a saltshaker or salt tablets. These dietary modifications help keep water in the bloodstream, which helps more blood reach the heart and the brain.
Certain foods or drinks can have an adverse effect on POTS symptoms in some patients. For example, alcohol almost always aggravates POTS. It diverts blood away from the central circulation to the skin and increases loss of fluids through urine. Caffeine can make some people more nervous and lightheaded, but for some it can help improve constriction of blood vessels. Your regular physician or POTS specialist can help you determine how your diet and certain medications could be helping or hindering your treatment.
Orthostatic Hypotension Particularly Affects Healthy Exercisers
Exercise is a protective factor for many health conditions, but orthostatic hypotension is particularly common among endurance athletes and other healthy, fit people. Although marathon runners may already have resting heart rates as low as 40 beats per minute, considerably less than the 60 to 100 beats per minute considered normal this is less likely a cause of dizziness. Instead, it might be related to fluid loss, as exercise can lead to dehydration. This type of orthostatic hypotension is generally harmless.
