The kidneys filter excess fluids and wastes from the blood; therefore, a healthy blood vessel system is crucial for kidney function. The nephrons, functional units of the kidney, serve as filters. However, high blood pressure can damage blood vessels and prevent the nephrons from receiving the necessary nutrients and oxygen. As a result, the kidneys can be permanently damaged if no treatment is sought.
Healthy kidneys secrete renin, an enzyme that controls blood pressure. On the other hand, a dysfunctional kidney may interfere with this mechanism, resulting in high blood pressure that is more difficult to regulate. In the United States, high blood pressure is the second most common cause of Chronic Kidney Disease. Both high blood pressure and kidney damage may go undetected in the early stages due to a lack of symptoms.
