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.
Water level balancing: As the kidneys are key in the chemical breakdown of urine, they react to changes in the bodyâs water level throughout the day. As water intake decreases, the kidneys adjust accordingly and leave water in the body instead of helping excrete it. Blood pressure regulation: The kidneys need constant pressure to filter the blood. When it drops too low, the kidneys increase the pressure.
