Center for Kidney Health


Kidney Disease is a common complication of long standing diabetes. After years, the kidneys can suffer changes in the blood vessels that are part of the system that filters waste and excess fluids from the body.

People cannot survive without kidneys.  If they fail to work, either dialysis or a kidney transplant is needed. 030812_WDI_Edward_Barnes-03_300pix

Focusing on Prevention: Early detection of kidney problems and appropriate treatment increase the likelihood of keeping your kidneys healthy. Meeting goals for blood glucose and blood pressure control can prevent, or at least slow, the development and progression of kidney disease.

The key to early detection is the identification of a protein in the urine called albumin. Later in the disease process, a substance in your blood called creatinine may be elevated and indicate declining function.

Without treatment, the disease progresses through stages, ending in kidney failure. Once the kidneys have reached “end-stage kidney disease”, dialysis (a method of removing wastes from the blood) or a kidney transplant must be performed.

The Center for Kidney Health has set prevention, slowing and reversal of chronic kidney disease as its primary goal.

The Center provides consultative care to patients at the WDI.

High Blood Pressure: Uncontrolled high blood pressure (hypertension) increases the risk of developing Diabetic Kidney Disease. Seventy percent of patients on dialysis have both diabetes and high blood pressure.

High blood pressure leads to damage of the kidney blood vessels increasing the risk of kidney failure.

Controlling blood pressure lowers the risk of diabetic kidney disease.

How can the Center for Kidney Health help you?

We implement the most up-to-date and individualized care plans available for the management of kidney disease. We will collaborate with the rest of the Diabetes team to coordinate your care. Here at the Center we will also work closely with your other physicians to ensure that you receive the safest and optimal care.

Our preventive prescription plan is as follows:

  • blood glucose control (Hgb A1C less than 7%)
  • blood pressure control (blood pressure less than 130/80)
  • cholesterol control (LDL cholesterol less than 100)
  • special blood pressure-lowering drugs, ACEinhibitors or angiotensin receptor blockers (ARBs) protect the kidney from damage

What can you do to protect your kidneys?

Know your numbers!

  • By checking the “glomerular filtration rate” (GFR) of your kidneys, your doctor can tell how well your kidneys are filtering your blood
  • Some Doctors may give you this number as a percentage of kidney function
  • There are 5 stages to kidney disease, and they are based on your GFR
  • Ask your doctor about your GFR

Know your ABCs!

A1c: Know your A1c level because glucose control is essential in the management of kidney disease
Blood Pressure: Know your blood pressure values. It is also important to track these values at home.
Cholesterol: Know your cholesterol level.  Ask your provider if you require medication to get your lipids under control.

Get regular check-ups!

  • Have your urine tested annually for the presence of protein or albumin.
  • Have your creatinine tested to calculate your GFR.
  • If the results of these tests are abnormal, have your doctor refer you to a kidney doctor for further treatment.

Exercise regularly!

Regular exercise can have the following effects on patients with Kidney Disease:

  • Better blood pressure control
  • Better control of diabetes
  • Improved heart function
  • Improved muscle function

* Work with our physical therapist to find an exercise regimen that is best for you.

Eat Healthy!

  • Limit your salt intake
  • Maintain a diabetic diet
  • Some patients may need to limit their protein intake, too
  • Some patients may need to limit their phosphorous or potassium intake

* Work with our registered dietitian nutritionist to find nutritional plan that is best for you. 

Know your medications!

  • Take all of your medications as prescribed
  • Keep an up-to-date list with you
  • Know what all of your medications are for
  • Inform your providers about any medications you have purchased over the counter

Educate yourself and others!

  • Attend diabetes education classes
  • Attend Kidney Smart classes (sign up today at
  • Bring family members along to any of your education classes

* Work with our educators.
