Why high blood pressure cause kidney disease?

High blood pressure can cause kidney damage, which is commonly referred to as hypertensive nephropathy. This king of nephropathy generally have two kind of clinical type,that is benign renal arteriolar sclerosis and malignant arteriolar sclerosis.Benign renal arteriolosclerosis is a long-term hypertension that leads to renal arteriolar hyalinosis,causing renal ischemic changes, glomerular and renal tubular dysfunction, and ultimately can cause renal fibrosis and renal failure, pathological changes and hypertension duration and severity. Malignant renal arteriolosclerosis is due to the rapid development of hypertension caused by renal artery diffuse fibrinoid necrosis, resulting in rapid deterioration of renal function.
Why high blood pressure cause kidney disease
The vast majority of patients with hypertension and renal changes can occur, with the increase of age, glomerular sclerosis also increased, but often it is a slow process, hidden, easily ignored, until the patient had nausea, weakness, nocturia and other symptoms or physical examination found that renal failure. There is some danger signal of hypertensive renal injury at the early stage, such as nocturnal polyuria, usually sleep at night after getting up to more than 2 times, and each time the urine volume is more than the amount of urine at night, more than half of all day long.
In addition, it can be found that some of the foam in urine increased, but most are not obvious. High blood pressure can cause kidney damage, kidney disease can also cause high blood pressure, the two closely related to each other, forming a vicious circle, which will lead to uremia patients unknowingly. Therefore, patients with high blood pressure must pay attention to the monitoring of blood pressure, blood pressure medication through the adjustment to the desired level, which has an important role in the protection of renal function. In addition, patients with hypertension must be regular physical examination, routine monitoring of urine and renal function, and timely treatment.

nephrotic syndrome nursing care plan

1.dietary intervention Nephrotic syndrome patients with hyperlipidemia can increased blood viscosity, hypoproteinemia, caused by insufficient effective blood volume, platelet hyperfunction and  nephrotic syndrome ,further exacerbating the hypercoagulable state, the thrombosis prone, the blood flow is slow, intravascular membrane damage, blood hypercoagulability is one of the three major factors of thrombosis, so the diet intervention on nephrotic syndrome patients, effective treatment of hyperlipidemia, prevention of thrombosis has important clinical significance, health education can strengthen the patients understanding of the complications of the disease , so as to establish effective compliance. First of all, responsible for the kidney disease patients repeatedly stressed the strict restriction of dietary fat and cholesterol intake. Fat content of not more than 30% of the total, cholesterol is not more than 300mg/d, encourage patients to eat more foods rich in unsaturated fa...

What is Hypertensive Nephropathy?

Hypertensive nephropathy is due to long-term increase in blood pressure in patients, gradually lead to renal arteriosclerosis, renal unit atrophy or disappear, clinically this high blood pressure caused by changes in renal structure and function, known as hypertensive nephropathy. Hypertensive nephropathy can lead to polyuria, nocturia, and then reduce urine output. If you can not get active and effective treatment, will develop uremia. Treatment of hypertension nephropathy on the premise that the blood pressure must first be reduced to normal, to avoid the continued damage to the kidneys, while recovering damaged renal function, so as to achieve complete recovery. what is renal hypertension?     Unlike hypertensive nephropathy, renal hypertension is caused by the disease of the kidney itself, mainly due to renal parenchymal disease or renal artery stenosis, obstruction caused. Accounting for adult hypertension of 5% to 10%, is the main component of secondary hypertension...
