Chronic Kidney Disease: Care Instructions


Chronic kidney disease happens when your kidneys don't work as well as they should. Your kidneys have a few important jobs. They remove waste from your blood. This waste leaves your body in your urine. They also balance your body's fluids and chemicals.

When your kidneys don't work well, extra waste and fluid can build up. This can poison the body and sometimes cause death.

The most common causes of this disease are diabetes and high blood pressure. In some cases, the disease develops in 2 to 3 months. But it usually develops over many years.

If you take medicine and make healthy changes to your lifestyle, you may be able to prevent the disease from getting worse. But if your kidney damage gets worse, you may need dialysis or a kidney transplant. Dialysis uses a machine to filter waste from the blood. A transplant is surgery to give you a healthy kidney from another person.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

Treatments and appointments

  • Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you have any problems with your medicine. You also may take medicine to control your blood pressure or to treat diabetes. Many people who have diabetes take blood pressure medicine.
  • If you have diabetes, do your best to keep your blood sugar in your target range. You may do this by eating healthy food and exercising. You may also take medicines.
  • Go to your dialysis appointments if you have this treatment.
  • Do not take ibuprofen, naproxen, or similar medicines, unless your doctor tells you to. These may make the disease worse.
  • Do not take any vitamins, over-the-counter medicines, or natural health products without talking to your doctor first.
  • Do not smoke or use other tobacco products. Smoking can reduce blood flow to the kidneys. If you need help quitting, talk to your doctor about stop-smoking programs and medicines. These can increase your chances of quitting for good.
  • Limit your use of alcohol and avoid illegal drugs.
  • Talk to your doctor about an exercise plan. Exercise helps lower your blood pressure. It also makes you feel better.
  • If you have an advance care plan, let your doctor know. If you don't have one, you may want to prepare one. It lets your doctor and loved ones know your health care wishes if you become unable to speak for yourself.


  • Talk to a registered dietitian. They can help you make a meal plan that is right for you. Most people with kidney disease need to limit salt (sodium), fluids, and protein. Some also have to limit potassium and phosphorus.
  • You may have to give up many foods you like. But try to focus on the fact that this will help you stay healthy for as long as possible.
  • If you have a hard time eating enough, talk to your doctor or dietitian about ways to add calories to your diet.
  • Your diet may change as your disease changes. See your doctor for regular testing. And work with a dietitian to change your diet as needed.
