What is the difference between postural hypotension and orthostatic hypotension?

What is the difference between postural hypotension and orthostatic hypotension?

Semantics: They mean the same thing. Postural hypotension theoretically could mean any change in posture that induces low blood pressure, but in reality this is only seen when assuming a standing-up position from seated or lying down. Orthostatic hypotension describes the same phenomenon. ...Read more

Hypotension (Definition)

Hypotension is defined as "low blood pressure". Blood pressure is measured as two numbers and expressed as systolic blood pressure (sbp) / diastolic blood pressure (dbp). The sbp is the pressure that is generated when the heart squeezes. Dbp occurs when the heart relaxes. 120/70 is considered normal in adults. Less than 100/60 (of either number) can ...Read more

Can you tell me about orthostatic or postural hypotension?

Can you tell me about orthostatic or postural hypotension?

Orthostatic hypotens: The significance has to do with the problems caused by dropping blood pressure with position change. This can be very problematic for people. See the following wiki for more details:

Separate postural/orthostatic hypotension and tachycardia diagnoses, how does this work?

Need details: It's possible to have both conditions seperately, but they could are more commonly related or part of the same condition. It's likely best to spend some time having a heart rhythm specialist, go over your testing and results, and explaining it to you. A good history and physical examination is also helpful. Good luck. ...Read more

Separate postural/orthostatic hypotension and tachycardia problems, or just one cause for both?

Separate postural/orthostatic hypotension and tachycardia problems, or just one cause for both?

Not the same: In postural or orthostatic hypotension, BP drops significantly when upright (because among other things, blood pooling). A mechanism the body uses to correct this low BP is to increase the heart rate in an effort to mobilize that pooled blood and increase BP (hydration may help). Abnormal tachycardias are due to electrical abnormalities in your heart and may need to be treated. See your doctor. ...Read more

What is the difference between the symptoms of vertigo and symptoms of orthostatic hypotension?

What is the difference between the symptoms of vertigo and symptoms of orthostatic hypotension?

Motion vs. Lighthead: Vertigo is defined as "the sensation of motion in the absence of motion." this will lead to the feeling that either you are moving in some way (spinning is common) or your environment is moving. People with orthostatic hypotension do not typically complain of motion, rather they feel as if they are lightheaded or as if they might faint. ...Read more

Is there a difference bet. Orthostatic hypotension and hypotension?

Yes: Orthostatic hypotension is change in blood pressure due to change in position. A low blood pressure may occur when you stand up. Hypotension is low blood pressure at all times, regardless of position ...Read more

45 minutes tilt test what would be the difference in results between pots and postural hypotension?

Heart rate: In pots there may a drop in BP upon standing but the bigger issue is a fast hr. In neurally mediated syncope (orthostasis) there is a drop in BP that is associated with either no change in hr (vasodepresor), or a cardioinhibitory response where hr slws. ...Read more

Orthostatic hypotension questionable. I thought more like tia. How can we tell for sure?

Hypotension vs TIA: Sometimes a diagnosis of orthostatic hypotension (classicallly, dizziness when you stand up) is hard to prove. There is a fairly elaborate test called "tilt table" testing, which can confirm the difficult cases. A TIA does not produce the same symptoms of lightheadedness/dizziness. A TIA produces brief neurological symptoms, loss of speech, weakness in a hand, etc. Can't be proven in retrospect. ...Read more

Can MS cause Orthostatic hypotension?

Can MS cause Orthostatic hypotension?

It can: Multiple sclerosis can be associated with with an autonomic dysfunction, as in abnormal function of the autonomic nervous system which controls things like our heart rates and blood pressures. Unfortunately, it isn't uncommon to see abnormal heart rate and/or blood pressure responses to normal things like sitting up from lying down or rising from seated to standing. ...Read more

How can I prevent orthostatic hypotension?

Slow Adjustments: Orthostatic hypotension can be prevented by gradually allowing your body to equilibrate in different phases of movement. For example, after laying in bed for prolonged periods of time, blood tends to pool away from the head. Sit up while still in bed, equilibrate for a few moments, and then proceed to stand. This gives your body's vasculature time to constrict and redirect blood appropriately. ...Read more

Is orthostatic hypotension one of the symptoms of hypernatremia?

What is the prognosis for patients with orthostatic hypotension?

Not dangerous, but..: This can lead to significant distress and even disability. It's important to remember there is nothing dangerous or life-threatening about this. However, if it happens often, it can cause significant anxiety, and avoidance of certain situations. If routine measures (e.g. Oral hydration) and meds don't work, rehab exercises to retrain the veins and arteries to self-regulate can be very helpful. ...Read more

Could edema neutralize or reverse my normal orthostatic hypotension?

Could edema neutralize or reverse my normal orthostatic hypotension?

A sign: Edema can be a sign that your "tank is full"-that your volume status is positive or in other words you are not deplete of fluid. That's important because in that situation there may not be much more to be gained by adding extra salt in your diet or hydrating more vigorously. If orthostasis still problematic, then you will likely need to turn to alternative therapies such as midodrine, etc. ...Read more

Can you tell me about orthostatic hypotension in 16 year old female?

Ortho hypo: Regardless of age, orthostatic hypotension refers to a condition when changes in position like from lying down to sitting up or from sitting to standing cause your blood pressure to drop making you feel light headed or feint. Dehydration or blood pressure medicine that is too strong are examples of common causes; there are others. ...Read more

Who specialises in treating the patients suffering from orthostatic hypotension and syncope?

Well: Many doctors are trained and capable to begin a work-up for this. Many times it just takes medication management, however if conservative measures and work-ups have not solved the problem a cardiology visit should help you get solutions. Not all syncope is heart or vessel related however and other specialists such as neurology may need to be included. ...Read more

In someone with orthostatic hypotension, how long do symptoms like headache last? Permanently until treated, 10 minutes after standing, 5 minutes...?

Up to 5 minutes.: The symptoms should normally last up to 5 minutes. However the patient has to be very careful and whenever he gets the symptoms of hypotension he should immediately lie down to avoid loss of consciousness. This will also help getting rid of dizziness and headache. It is always better to treat the cause of hypotension. ...Read more

Was leaning over on my phone for a few minutes when I stood up 3/4ths of my vision blacked out. Was this just orthostatic hypotension and is it benign?

Was leaning over on my phone for a few minutes when I stood up 3/4ths of my vision blacked out. Was this just orthostatic hypotension and is it benign?

You are correct: This is orthostatic hypotension, which in a young person usually indicates some degree of dehydration. This is much more likely if you are in a hot environment. Be sure to drink enough water so that when voiding, the urine looks like water to be sure that you are not dehydrated at all.
Changing posture a little more slowly will also prevent this by giving more time for adjustment of the bp. ...Read more

Can severe anxiety cause orthostatic hypotension?

Can severe anxiety cause orthostatic hypotension?

Yes, but rare: Anxiety can have a myriad of effects, and it could cause this. Basically it is a fall in blood pressure due to positional changes, and would be more common for anxiety to raise blood pressure than reduce it, but it could be rarely implicated. It can have many causes from innocuous sources to serious medical problems. If occurs often see your md to rule out problems. ...Read more
