Why Does My Diastolic Pressure Raise When I Stand Up
You need: Higher BP when standing to supply the brain with blood and overcome effects of gravity....Systolic should also rise. ...Read more
Why would you?: A low diastolic blood pressure could be due to leaking of the aortic valve or other problems so finding the cause is important. If you feel well, a low pressure, diastolic or systolic, may not be a bad thing. People with relatively low blood pressure live longer. And, how low are you talking about? ...Read more
Changes are common:
Usually systolic and diastolic BP will drop minimally while standing unless you are dehydrated.
If you are healthy and do not have hbp, there is no use in measuring BP and could be generate plenty of anxiety.
If you want to be healthy, I rather you spend your energy in exercising and eating right. ...Read more
Here are some reason: During excercise the muscles increase demand for blood and therefore the arterial system is dilated for increased blood flow. Additionally excercise in general increases the compliance of the vessels and as a result diastolic blood pressure is decreased. ...Read more
Nope: Some people who walk around and feel well have diastolic bps of zero. (at least as estimated by a BP cuff which is an indirect measurement). My only caveat: get an echo and be sure you don't have aortic regurgitation which can be severe, cause no symptoms for years, and be hard to detect with a stethoscope. ...Read more
Several reasons: Most high blood pressure is idiopathic (no reason, you just have it) whether it is systolic or diastolic. It runs in families so if your parents have it, you are more likely to get it. There are occasion cases secondary to specific causes such as adrenal tumors, kidney problems, or narrowing of the aorta (called coarctation) and that is called secondary hypertension. ...Read more
Vascular tone: Both systolic and diastolic pressures are significantly impacted by the level of vascular tone or "resistance" or restriction to a given rate of blood flow. Although we have excellent medication options for managing vascular resistance, I have found that good cardiovascular conditioning seems to positively impact the diastolic blood pressure by enhancing "run off" in the peripheral vascular bed. ...Read more
Artery Stiffness: The diastolic blood pressure or the "bottom number" when the blood pressure is taken is when the pressure at which the heart beat is no longer heard by the stethescope. It is related to the stiffness of the arterial tree in the body. The stiffer the artery the higher the diastolic pressure. ...Read more
Whenever you want: Diastolic blood pressure refers to the pressure in the arteries during the period of heart's relaxation, i.e. Once it finished ejecting blood during contraction. For every single heart beat, there is the period of contraction ("systolic blood pressure") and the relaxation ("diastolic"). In any single cardiac cycle, each of these arterial pressures can be measured. ...Read more
DPTI: It is a measure of coronary blood supply. Multiply the coronary perfusion pressure times the diastolic tmie. Cpp =diastollic blood pressure minus the left vetricular end diastolic pressure. Diastolic time is 60sec/heart rate-0.2seconds. The 0.2 is systolic time (fixed at 0.2s). Coronary flow occurs during diastole and relates to the pressure and how long diastole lasts. Now ask me what the evr is. ...Read more
How low?: If you do not have any symptoms and is it is between to 60 mmhg, it is probably normal for you. It is hard to diagnose someone just based on a number, may things can cause a drop in the diastolic bp, infections, dehydration, hormonal problems, heart problems, pregnancy, blood loss, lack of nutrient among many others. ...Read more
HTN: The pattern of high blood pressure is that young people tend to have high diastolic pressure and elderly people tend to have high systolic pressure. Both/either are harmful and should be controlled. The cause of essential hypertension has never been adequately determined. There is a genetic component and obesity is a risk factor. ...Read more
Most idiopathic: Most systolic or diastolic hypertension is 'essential" (no reason, you just have it). It does run in families. There are certain unusual causes such as adrenal tumors and blockage in the arteries that supply the kidney which cause "secondary hypertension". (there is a cause.) coarctation of the aorta is another example of "correctible hypertension.". ...Read more
Less than 80 mmHg: Ideal is less than 80 mmhg and perhaps higher than 50 mmhg, would watch between 80 and 90 mmhg, keep to a low salt diet and try to exercise at least three times a week to ward off higher numbers; if higher than 90 mmhg, would seek medical attention. ...Read more
Depends: "too low" implies that it is a problem. 70 is lower than average but would not raise an eyebrow. 50-60 is unusual and would lead me to think, why? If you feel well it is probably not a problem. But if the diastolic pressure is on the low side, I would consider things that might cause that even if the patient is well. Leaking of the aortic valve for instance can cause a low diastolic pressure. ...Read more
60 mmHg: The normal diastolic pressure for adults is 80mmhg. Can be considered acceptable from 70 to 85 mmhg. Higher than that is prehypertension. Lowr than 70 mmhg is common normal finding in patients older than 70 years old. Diastolic blood pressure lower than 60 mmhg in adults younger than 65yo raises the ssupicion of valvular problems. ...Read more
Blood pressure: The peripheral vasculature dilates with exercise this facilitates runoff from the arterial system during both phases and decreases the pressure in diastole ...Read more
See doc, likely meds: Elevated systolic and diastolic BP implies likely needs for meds to control bp. If elevations are borderline high (130-140/80-90), would suggest checking at home, and then consider weight loss, alcohol and salt restriction to help. If frequent rechecks still show BP often in excess of 140/90, need to start med, along with physical exam and lab tests. ...Read more
Heart cycle: The heart is a pump that works in a cycle. Each heart beat has 2 components: systole when heart contracts to pump blood and diastole when heart relaxes to fill with blood. That is why each blood pressure measurement has 2 numbers: the upper one is systolic blood pressure and lower one is diastolic blood pressure. ...Read more
Pulsatile flow: Blood flows through the arteries in a pulsatile fashion, propelled by rhythmic contractions of the left ventricle. The pulsatile flow means that the pressure is higher in systole (when the heart contracts) and lower in diastole (when the heart relaxes). Systolic pressure is the peak pressure and diastolic pressure is the lowest pressure. ...Read more
Arteries and veins: Systolic pressure is the pressure in your artery during during cardiac contraction as blood rapidly flows into the arteries. It measures to certain degree the elasticity of the vessel. Diastolic pressure is the pressure after contraction when no active flow is going and measures the resting tone of the artery. CVP is the venous pressure closest to the heart or the vena cavae. ...Read more
Probably not: A low diastolic blood pressure with a normal diastolic blood pressure often is of no significance. In some people, their blood pressure sounds can be heard all the way down to 0 when nothing is wrong. A large difference between systolic and diastolic pressures (wide pulse pressure) may indicate aortic regurgitation, however. Check with your doctor. ...Read more
A little high: I am assuming you mean systolic of 130, not 13. A systolic of 130 is normal for most people but there are some conditions where we would like it a bit lower. Diastolic blood pressure should definitely be below 90 and 80 would be even better. A single measurement of a high blood pressure is not concerning but if the diastolic stays high you should see MD. Also avoid salt, caffeine and alcohol. ...Read more
