Renal Insufficiency


The role of the kidneys is to remove waste products and excess water from the body. When the kidneys do not function normally, waste products build up in the blood. The early stage of this process is called “renal insufficiency”. If renal insufficiency worsens it can lead to chronic renal failure. This allows excess water, waste and toxic substances to build up in the body. This can become a threat to life, requiring dialysis or a kidney transplant to stay alive.

Diabetes is the leading causes of renal insufficiency.  Other causes include high blood pressure, hardening of the arteries, lupus, inflammation of the blood vessels (vasculitis), prior viral and bacterial infections, and others. Certain over-the-counter pain medicines can cause renal failure when taken often over a long period of time. These include aspirin, ibuprofen (Advil, Motrin) and related anti-inflammatory medicines.

Home Care:

  • If you have diabetes, talk to your doctor about the quality of your blood sugar control. Ask about any changes needed to your diet or medicines.

  • If you have high blood pressure:

    • Take your blood pressure medicine.

    • Take up a regular exercise program that you enjoy. Check with your doctor to be sure your planned exercise program is right for you.

    • Reduce your salt (sodium) intake. Your doctor can tell you how much salt per day is safe for you.

  • If you are overweight, talk to your doctor about a weight loss plan.

  • If you smoke, you must quit. Smoking worsens kidney disease. Talk to your doctor about ways to help you quit. For more information, visit the following links:
