Renal Insufficiency


Your kidneys remove waste products and extra water from your body. When your kidneys don’t work as they should, waste products build up in your blood. The early stage of this process is called renal insufficiency. If renal insufficiency gets worse, you can develop chronic renal failure. This allows extra water, waste, and toxic substances to build up in your body. This can become life threatening. You may need dialysis or a kidney transplant. The most serious form of renal insufficiency is end-stage renal disease.

Diabetes is the main cause of renal insufficiency.  Other causes include:

  • High blood pressure

  • Hardening of the arteries

  • Lupus

  • Inflammation of the blood vessels (vasculitis)

  • Viral or bacterial infection

Some over-the-counter (OTC) pain medicines can cause renal failure if you take them for a long time. These include aspirin, ibuprofen, and other nonsteroidal anti-inflammatory drugs (NSAIDs).

Home care

Follow these tips when caring for yourself at home:

  • If you have diabetes, talk with your health care provider about controlling your blood sugar. Ask if you need to make any changes to your diet, lifestyle, or medicines.

  • If you have high blood pressure:

    • Take your prescribed medicine. Your goal is to lower your blood pressure to less than 130/80, or to the goal set by your provider.

    • Do a regular exercise program that you enjoy. Check with your provider to be sure your planned exercise program is right for you.

    • Cut back on the amount of salt (sodium) you eat. Your provider can tell you how much salt each day is safe for you.

  • If you are overweight, talk with your provider about a weight loss plan.

  • If you smoke, quit. Smoking makes kidney disease worse. Talk with your provider about ways to help you quit. For more information, visit:
