Blood pressure and kidney disease are very closely related to each other. In certain cases very high blood pressure. In certain types of hypertensive conditions can damage the kidneys and cause chronic kidney disease and the flip is also true where chronic kidney disease in a patient who did not have a blood pressure problem can cause high blood pressure. So the kidneys are very important in regulating salt and water levels in the body and when the kidneys doesn’t work so well in the steering of chronic kidney disease, salt and water are not excreted well from the body. So salt and water accumulates and when this happens, the blood pressure can rise and the patient can develop high blood pressure. So in patient who have chronic kidney disease and have developed high blood pressure thereafter, it is important to follow dietary restrictions. Low salt diet is very important and in more severe stages of chronic kidney disease and end stage kidney disease, where patients are on dialysis, they may have water restrictions as well. The amount of fluid that they can take in a day may be restricted. And also in coordination with that in patients who have chronic kidney disease and have high blood pressure, the medications for blood pressure, may be a little more specific to their kidney disease. They may be required to take diuretic medications again to excrete more salt and water. So blood pressure may be managed a little bit differently in the patient who have chronic kidney disease. They may also be on certain medications that control the blood pressure that are protective to the kidneys in the long run.
