What is Nephritis hypertension? Many patients have a headache this problem, he got nephritis why hypertension, if the blood pressure does not fall easily lead to more serious chronic nephritis, chronic nephritis disease can not be controlled, so how to reduce blood pressure in chronic nephritis patients with chronic nephritis each become most concerned about. So how to reduce the pressure of chronic nephritis in order to control the development of chronic nephritis?:
1, the increase in renal pressor substances and reduce blood pressure:
Chronic glomerulonephritis due to glomerular capillary spasm, blocking the renal tissue ischemia, juxtaglomerular cells continue to secrete renin, the renin angiotensin aldosterone system induced by systemic vasoconstriction, increased blood pressure.
At the same time due to kidney damage, kidney secretion of depressor substances, such as prostaglandins and bradykinin peptide system, the factors to reduce further the expansion of blood vessels, vascular spasm increased, blood pressure becomes higher.
2, increased blood volume:
Glomerular diseases can cause glomerular filtration rate decreased, and the renin angiotensin aldosterone system activation leads to renal tubular reabsorption of sodium and water increase, and reduce some natriuretic substances can also add heavy water sodium excretion reduced, resulting in reduced urine discharge, increased blood volume, blood pressure.
3, systemic small artery spasm, Arteriosclerosis Caused by high blood pressure:
Renal hypertension duration is long, can appear arteriolosclerosis, that systemic arterial resistance not only increased, elevated blood pressure, and stubborn and poor response to antihypertensive drug.
