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.
However, studies have shown that you are probably most at risk if you have diabetes, high blood pressure, or if a close member of your family also suffers from kidney disease. Hypertension can cause chronic kidney disease by making the kidneys work too hard to remove the excess water from your blood. Making a bad situation worse, kidney malfunction may cause high blood pressure that adds even more strain to weakened kidneys.
