kidney failure high blood pressureHigh blood pressure is also called Hypertension and is the second leading cause of kidney failure. It refers to a medical condition in which the blood pressure in the arteries is elevated. Temporary high blood pressure brings no damage to us, but once it lasts a long time, we need to take medical measurements immediately, particularly those who have kidney failure.

High blood pressure has complicated relationship with kidney failure, as it may occurs as a symptom of kidney failure, also may works as the root cause of kidney problem. Therefore, for people with both high blood pressure and kidney problem, it is necessary for them to found out the relationship between high blood pressure and their kidney problem.

High blood pressure affects kidney failure in the following several ways:

1. High blood pressure causes kidney damages directly

Kidneys are supplied with dense blood vessels, and high volumes of blood flow through them. Over time, uncontrolled high blood pressure damage arteries around the kidney directly, which will reduce blood flow through the kidneys.

2. High blood pressure accelerate kidney failure

As we know kidney works a filter. In kidney, glomerular filtration function is composed of a great number of blood capillary which helps to transfuse blood. Long-term high blood pressure damages these blood capillaries directly and reduce filtration area. When glomerular filtration are is decreased, blood filtered by kidney decreases and kidney function decreases.

3. High blood pressure worsen proteinuria

A poor control of blood pressure is unfavorable to effective control of proteinuria. Long time high blood pressure damage vascular wall, which can allow much more protein leak out. For patients with high blood pressure, if they want to reduce protein in urine effectively, they must get their blood pressure under controlled firstly.

Since high blood pressure is so closely related with kidney failure, it is very beneficial for kidney failure patients to control their blood pressure into normal range. At presents, many oral medicines show obvious treatment effects in lowering blood pressure, but if you do not want to take oral medicines, you can have a try about Chinese medicines.
