A number of diseases can cause an increase in blood pressure (also called hypertension). These range from chronic liver disease to kidney failure to congestive heart failure to atherosclerosis.
Upon standing, there is brief slight drop in BP followed by a slight increase above the sitting BP after about a minute or two. Prolonged standing may result in an additional drop in BP.
The hydrostatic influence is responsible for this, along with the elevation in pulse upon standing. Research has shown this to be mainly a result of the carotid sinus reflex. The position of the thighs - horizontal or vertical - controls this reflex. Variations in the intensity of the reflex vary from patient to patient and day to day, and can be different for patients with blood pressure or other cardiac disorders.
EASY ANSWER: GRAVITY
My mom had this and after doctor after doctor I discovered what it was...
Nice to have a real answer to a real problem....
No. If you're healthy, then it goes down.
Blood pressure is higher in taller animals because the pressure in the arteries has to overcome the effect of gravity. This response may be expressed as: p = g.Ïh where p is the pressure, g the acceleration due to gravity, Ï is the density of the liquid, and h is the height. So blood pressure has to increase linearly with the distance between the heart and the highest point that blood must reach.
The Heart has to work harder to supply to the lower body and then fighting gravity to return uphill as compared to lying down as in when your sleeping the heart works much easier.
Try pouring out a glass of water into another glass and then see how much work it is to make that same water go uphill back into the first glass , a world of difference!
But... without a good heart workout the heart would become a weak pump and quit.
Blood pressure is a gauge pressure (aka hydrostatic pressure) and it is directly proportional to density x pull of gravity x height of liquid above the point of measurement. The density of blood is constant and so it the pull of gravity. The only thing that changes is the height of the blood above point of measurement. The more fluid above, the higher the gauge pressure, hydrostatic pressure or blood pressure. The concept is the same as when you dive and the pressure increases the further down you dive since there is more fluid above you. When you're sitting down with your arm bent, the blood pressure is not as high since the blood in all of the forearm is at the same height. Also, the pressure in your lower leg is not as high when your sitting down because all the blood that flows through your quads is at the same height and thus not contributing to the gauge pressure. When you stand up and have your arms straight down, the blood flowing through your fore arms and your quads is now contributing to the total height of blood above the point of measurement. Back to the diving analogy... If you dive down a cave. The gauge pressure does not change in the horizontal parts of the cave but instead only the vertical parts when you dive down. Now imagine if you could stretch out the entire length of that same cave into one long vertical cylindar. The pressure at the end or bottom of the cave is now greater since there is a greater height of fluid above. Hope that helps. Sorry about the anatomy terminology but I'm sure the main point was made.
Because your leg muscles and others are more relaxed.
nicotine
It'll Increase your blood pressure because the blood is being rushed to the area where your flexing, which causes your blood pressure to rise.
As such there is no special reason to have high blood pressure in teens except psychological stress. Stress hormones will rise the blood pressure.
Sodium causes you're blood pressure to rise as well as causing bloating
when heart rate increases, blood pressure rises. When heart rate decreases, blood pressure drops. medications, and diseases affects the blood pressure. Source: About Blood Pressure
Aldosterone causes sodium to be retained and potassium to be excreted and blood pressure to rise.
A raise in blood pressure causes this. U should get an at-home blood pressure moniter and check your levels after you excercise, to ensure that they aren't in the danger zones. It's normal for blood pressure to rise, but there's still an unhealthy level that should be watched out for.
yes
Yes. Pain can cause a rise in the blood pressure.
It causes blood pressure to increase.
Yes. Insulin production usually decreases with age, which causes blood sugar to rise. This can be counteracted with exercise and a low-GI diet.
No. Renin causes the blood pressure to rise. By low blood pressure the body releases Renin from the kidneys. Renin cleaves an inactive peptide, called Angiotensinogen, converting it to Angiotensin I. Angiotensin I is then converted to Angiotensin II by ACE (Angiotensin-Converting-Enzyme). Angiotensin II causes vasoconstriction and thus an increase in blood pressure.
