What Is the Relationship between Hypertension and Kidney Disease?

Many Kidney Disease patients suffer Hypertension(high blood pressure) and some patients with Hypertension(high blood pressure) may develop kidney disease. What is the relationship between Hypertension(high blood pressure) and Kidney disease?

Kidney disease patients often suffer Hypertension(high blood pressure). That is because the damaged renal parenchyma can active the secretion of renin, which increases the active of Angiotensin I (AGTI) causing vasoconstriction of arteriole all over the body. As a result, it leads to Hypertension. Moreover, renin and AGTI both can promote the secretion of aldosterone, leading the retention of excess water and sodium. As a result, it further increases blood volume and aggravates the condition of Hypertension(high blood pressure).

Long term of Hypertension(high blood pressure) can further damage to kidney by leading to the condition of arteriolonephrosclerosis. Besides, Hypertension can also cause the condition of ischemia and anoxia, which also injures kidney and other organs.


So patients with Hypertension(high blood pressure) should well control their blood pressure to prevent from Hypertensive Nephropathy. Kidney disease patients should take positive treatment to well control their condition, so long as their injured kidney is well repaired, Hypertension(high blood pressure) will be effectively under controlled.
