What are the common causes of low renin hypertension

summary

I have been suffering from high blood pressure for several years. I have been relying on drugs for maintenance treatment. Recently, the drugs could not be controlled, so I went to the hospital for examination. After examination, I was told that I had adrenal hyperplasia. The doctor said that it might be low renin type hypertension and I need to change dressing. Today, let me learn from you the common causes of low renin hypertension.

What are the common causes of low renin hypertension

The first reason is: renin dependent hypertension: its pathogenesis is renal artery stenosis, decreased renal perfusion pressure and renal parenchymal diseases, as well as cell tumors secreting renin, which can make the parabulbar cells release a large amount of renin, resulting in increased activity of angiotensin II and contraction of small artery wall in the whole body, resulting in hypertension.

The second reason is that renin and angiotensin II can also increase aldosterone secretion, resulting in retention of sodium and water, resulting in increased blood volume and * hypertension. The release of kallikrein and prostaglandin decreased after renal parenchymal injury. The decrease of these vasodilators is also an important factor in the formation of hypertension.

The third reason is: high renin hypertension is different from other hypertension, the main cause of the disease is abnormal renin secretion, in addition to the increase of blood volume in the blood vessels, the artery is in a state of contraction, which can not be determined by measurement.

matters needing attention

There are many reasons for low renin type hypertension. We don't rule out whether it is secondary hypertension caused by kidney reasons. We need to go to the hospital to make a diagnosis, and then treat symptomatically according to our actual condition.
