Prevention / Delay

Chronic kidney disease may sometimes be prevented by controlling the other diseases or factors that can contribute to kidney disease. People who have already developed kidney failure also need to focus on these things to prevent the complications of kidney failure.



  •  Keep your blood pressure below 130/80
  • Keep your blood sugar within a target range if you have diabetes. Talk with your doctor how often to check     your blood sugar.
  • Don’t smoke or use other tobacco products. Smoking can lead to atherosclerosis, which reduces blood flow to the kidneys and increases blood pressure.
  • Stay at a healthy weight. This can help you prevent other diseases, such as diabetes, high blood pressure, and heart disease.
  • Follow instructions on over-the-counter medications. Kidney disease can be caused by the improper use (such as taking too many) of non-steroidal anti-inflammatories (NSAIDs), such as aspirin and ibuprofen. If you need to take painkillers, make sure you follow the instructions. This can help to avoid kidney damage.
  • A healthy diet is important for preventing chronic kidney disease. It will lower the amount of cholesterol in your blood and keep your blood pressure at a healthy level. Eat a balanced diet that includes plenty of fresh fruit and vegetables (five portions a day) and whole grains.
  • At least 150 minutes of moderate-intensity aerobic activity (such as swimming, cycling or dancing) every week, is recommended to lower your risk of developing CKD and help lower your blood pressure.

Food Intake

By eating the right foods and avoiding foods high in sodium, potassium, and phosphorus, a person may prevent or delay some health problems from CKD. Learning about calories, fats, proteins, and fluids is important for a person with advanced CKD. As CKD progresses, nutritional needs will change. Being extra mindful about what is eaten can reduce the amount of fluid and waste build-up, helping to minimize symptoms and side effects of CKD. Dietary assessment includes review of your intake of energy and important nutrients such as:

  • Most people should limit the amount of sodium in your diet. Sodium helps your body to retain a healthy fluid balance. But having renal disease means your kidneys cannot eliminate excess sodium and fluid from your body. As sodium and fluid buildup in your body, your blood pressure will increase and you will feel uncomfortable. It can also cause swollen ankles, puffiness, a rise in blood pressure, shortness of breath, and/or fluid around your heart and lungs.
  • Watch out the sugar intake. The sugar you eat eventually makes its way into your bloodstream, where it can elevate your blood sugar levels. The more sugar you eat, the more fluctuations you will have in your blood sugar levels. One of the damaging effects of a diet high in sugar and other refined carbohydrates is that it puts you at risk for developing diabetes. If you already have diabetes, too much sugar in your diet will affect your blood sugar level.
  • Protein can be pose a problem for chronic kidney disease (CKD) patients. Healthy kidneys have millions of nephrons that can filter these protein waste products. It is then removed from the body in the urine. Unhealthy kidneys lose the ability to remove protein waste. Protein waste starts to build up in the blood. As kidney function gradually decline, more waste will accumulates. To help reduce waste accumulation, a lower protein diet may be prescribed.
  • Potassium is an important mineral in the blood helping your muscles and heart to work properly. Too much or too little potassium in the blood can cause an irregular heartbeat. As your kidney disease progresses, you may need to limit the amount of high-potassium foods you consume. Potassium is found in large amounts of fruits and vegetables such as mushroom, banana and pumpkin.


Take control of your diet. Get plenty of exercise, stay healthy and keep on track. Talk with your care team to determine individualized dietary guidelines based on lab tests and your stage of CKD.
