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.

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: http://en. Wikipedia. Org/wiki/orthostatic_hypotension.

Could a 19 yr old have orthostatic (postural) hypotension?

Could a 19 yr old have orthostatic (postural) hypotension?

Yes: More common in younger patients. Get evaluated if you have symptoms or are concerned.

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

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.

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.

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.

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

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

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.

Does orthostatic hypotension cause a 'low flow' tia?

It can: It can if it is low enough or if there is already some cerebrovascular disease.

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

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.

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.

Can tmjd cause orthostatic hypotension?

TMJ/orthostatic symp: In my 30 years of treating TMJ patients, I have not seen orthostatic hypotension (low blood pressure) related problems.

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.

Could anxiety cause orthostatic hypotension?

Could anxiety cause orthostatic hypotension?

I think it could be: More likely that a person with orthostatic hypotension could develop anxiety in the anticipation of becoming symptomatic.

Why can levodopa cause orthostatic hypotension?

Hypotension: Because it can decrease the sympathetic outflow and thus decreasing your BP

Can I faint from having orthostatic hypotension?

Yes: Orthostatic hypotension means drop in blood pressure due to postural changes, usually abruptly standing up. When BP drops there is strong possibility you-can faint.

Could having surgery cause orthostatic hypotension?

Orthostatic: Yes. If you loose more blood or fluids during surgery, it could cause orthostatic hypotension.

How can I prevent the effects of my orthostatic hypotension?

Get up slowly: See your dr. And make sure your antihypertensive medications are correct, make sure you are well hydrated, and get up slowly.

Postural Hypotension (Definition)

Postural hypotension describes a phenomenon that occurs in some people -- usually otherwise healthy -- in which after they rise from either a prone, or sitting, position their blood pressure quickly becomes lower. As a consequence, the affected person becomes uncomfortably dizzy, or lightheaded for ...Read more
