High blood pressure is dangerous, partly because there are no symptoms, so organ damage can occur slowly without being recognized. Renal hypertension can cause chronic kidney disease. This is a slow decline in kidney function. Until the condition is well advanced, chronic kidney disease also causes no symptoms. Because there are usually no symptoms, a doctor may suspect renal hypertension when someone has uncontrolled high blood pressure despite multiple medications or has unexplained chronic kidney disease.
Hypertension is unique in that it can cause CKD or be the result of it. Hypertension can cause damage to the arteries resulting in insufficient blood flow to the kidneys, leading to CKD. One function of the kidney is to produce hormones to help regulate blood pressure.
