High blood pressure
People with chronic kidney disease often have high blood pressure, and this can damage your kidneys further.
Your doctor may offer you medicine to help control your blood pressure. The type of medicine will depend on your circumstances. Even if you don't have high blood pressure, you may be offered certain types of these medicines to help prevent your kidney disease from getting worse, especially if you have high levels of protein in your urine or if you also have diabetes.
Your doctor will look at your blood pressure and the levels of protein in your urine before deciding whether to do this and will discuss it with you.
If you are offered medicine for high blood pressure, you may need to try different doses to find the right dose for you. To make sure this is done safely, you should have blood tests to monitor how well your kidneys are working (called a GFR test) and your blood potassium levels. This should happen before you start taking the medicine, 1 or 2 weeks after you start, and each time the dose is increased.
If your blood potassium levels are high (called hyperkalaemia), your doctor will want to carry out other checks and tests, and you may be offered treatment for this. You may not be able to start or continue treatment for high blood pressure until your potassium levels are lowered.
