Why can Chronic Renal Failure Cause Hypertension?

The reason why Hypertension can happen to Patients with Chronic Renal Failure is

complex. For Chronic Renal Failure patients in early stage, the change of exchangeable sodium in the body can not be easily detected. For Chronic Renal Failure patients, the change of blood pressure and their sensitivity to salt are higher than normal people.
Respiratory Signs of Severe Renal Failure
For most Chronic Renal Failure patients in end stage, their Hypertension is caused by water and sodium retention, or the increase of blood volume and extracellular fluid volume.

At this moment, the increased level of blood pressure has a perfect positive correlation with salt intake. Stroke volume of patients increases while plasma renin activity decreases. Later stroke volume may return normal, but obstruction in peripheral vessels can be heightened. At the moment, anemia and arteriovenous fistula also can aggravate the load of heart. After taking dialysis, blood pressure can reduce to normal level due to dehydration.Can Kidney Failure Cause Kidney Shrinkage Chinese Medicines for Renal Failure Patients with Swollen Eyelid

For a small part of patients, there may appear water volume declined and plasma renin activity increased due to various factors such as vomiting or diarrhea. At the moment, if patients take dialysis, there may occur obvious raise of blood pressure due to dehydration, leading to stubborn Hypertension. Under this situation, it is better to take several types of hypotensor at the same time in order to control blood pressure. Some reports also say that Renal Failure Hypertension is caused when high level inhibitor of sodium transport directly or indirectly increase the concentration of calcium ion in smooth muscle cells, and then lead to vasoconstriction, causing increase of blood pressure.
