Why Can Hypertension Cause Renal Failure

According to the research, most patients with Hypertension will suffer from kidney disease with the development of high blood pressure. If patients can not well control the blood pressure and take no timely treatments, renal blood vessels will be damaged, which can lead to the blood insufficiency of kidney and cause hypertensive Renal Failure.

The main clinical manifestations of hypertensive Renal Failure are as follows:

1. In the initial stage, patients with hypertensive Renal Failure show no obvious symptoms and the abnormalities of renal function can only be detected by relevant clinical tests. So, in the early stage of hypertensive Renal Failure, patients tend to be ignorant of their own situation and pay no attention to it, thus missing the best time for treatment.

2. When the disease develops into mild-moderate degree, although the metabolic wastes like urea nitrogen in blood go up, only slight symptoms can be seen in clinical cases. For the patients in this phase, their kidneys can not absorb, at night, the same amount of water from urine and concentrate the urine just as they do in daytime, so patients will have more urination at night, which can lead to increased urine volume. On the other hand, when Hypertension patients get Renal Failure, most parts of the kidney become fibroid and the healthy parts are very less. Therefore, the kidney can not expel enough water and salt out of the body, which can drive the blood pressure up. As a result, high blood pressure and Renal Failure will form a vicious circle, mutually aggravating each other.

3. In the mid-late stage, with the deterioration of the disease, the metabolic wastes in the body will get more and more, and these toxins will pose negative impacts on patients’ various systems, such as muscle, nerve, alimentary canal, brain and skin. Then, patients will show a series of clinical symptoms, such as jerk, myasthenia, muscle spasm, stinging pain in hands and feet, vomiting and nausea, declining appetite, ozostomia, anemia, decreased body weight, tawny skin color, whiter powder on the surface of skin, systemic itching, convulsions and so on. At that time, the disease has developed into Uremia and the following treatment will become very difficult.


So, for Renal Failure patients, they should take effective measures to control the blood pressure; on the other hand, they should receive relevant treatments to repair damaged renal functions which can contribute to lowering the blood pressure.
