Why does kidney disease have high blood pressure

summary

My cousin is very weak. She always feels tired and dizzy when doing anything. Her blood pressure is a little high. She went to the hospital for examination. As a result, she has kidney disease. The doctor prescribed some drugs to control it. Now let me tell you why kidney disease has high blood pressure.

Why does kidney disease have high blood pressure

First, hypertensive nephropathy is the damage of renal structure and function caused by primary hypertension, which is divided into benign hypertensive nephrosclerosis and malignant hypertensive nephrosclerosis. The former is due to the long-term effect of benign hypertension (≥ 140 / 90 mmHg) on the kidney, while the latter refers to the renal damage caused by the development of malignant hypertension (diastolic blood pressure > 130 mmHg) on the basis of primary hypertension. If hypertension and kidney damage exist at the same time, they will cause and effect each other and aggravate each other.

Second: the kidney itself is used to filter toxins in the body, excrete excess water and sodium salt through urine, and prevent proteins and blood cells from leaking out of blood vessels. High blood pressure increases the blood pressure in the blood vessels, leading to the leakage of protein into the urine. Once the protein leaks out, it will damage the filter system of the kidney. If hypertension is not well controlled for a long time, the structural damage is difficult to reverse, and renal function damage will gradually appear, even chronic renal failure. The final serious stage is uremia.

Thirdly, the patients with benign hypertensive nephrosclerosis are more than 40-50 years old, and the history of hypertension is more than 5-10 years. In the early stage, only nocturia increased, accompanied by microalbuminuria, followed by proteinuria (generally + to + +), some patients may have a small amount of red blood cell urine. Hypertension can lead to other organ complications: arteriosclerotic retinopathy, left ventricular hypertrophy, stroke. The course of disease progressed slowly, a few of them gradually developed into renal failure, most of them had mild renal damage and abnormal urine routine.
