It is said by experts that at present there are more than 90 million people
in China who are suffering from kidney disease, 30% of whom are caused by high
blood pressure. In addition, there are more and more young people who are
suffering from high blood pressure. So we can also say, high blood pressure and
kidney disease is a pair of partner, which interact each other and even lead to
a vicious circle.
In normal condition, 19% of blood in afferent arterioles is filtrated into
renal tubules by renal glomeruli, thus forming original urine. 99% of original
urine can be reabsorped by renal tubules into blood circulation, which can
maintain the balance of body infusion. In this way, the waste things are
discharged, and the blood content is also maintained balanced relatively. Once
there is lesion in the kidney, the blood circulation will be blocked, and the
blood flow in the kidney will decrease, which can activate some factors which
can increase the blood pressure in the body such as renin and so on. These
factors can lead to the whole arteriolospasm and increased resistance of
arteriole, thus causing increased high blood pressure. In addition, once kidney
is damaged, it can not discharge out the sodium and water, which leads to the
retention of water and sodium, thus increasing the blood content and increased
high blood pressure. In a world, kidney plays an important role in adjusting the
metabolism of water and sodium and in secreting materials which can activate the
blood vessels. Materials which can increase the retention of water and sodium
increase, and those which can lead the blood vessels to shrink decrease, so the
rate of high blood pressure increase accordingly.
What’s more, kidney is also a main organ which is influenced by high blood
pressure. Long time high blood pressure can lead the inner pressure in the
capsule of renal glomeruli to increase, cause fibrosis of renal glomeruli, which
will finally develop into renal failure. At present, in the treatment of high
blood pressure, there are some wrong ways.
Firstly, when people have high blood pressure, they go to Shijiazhuang Kidney Disease hospital but only
test whether the heart functions well. They do not go to have a test of renal
function such as urine test and blood test. So the damage of kidney is usually
ignored.
