Kidney disease from diabetes is the most common cause of kidney failure in the United States. That said, diabetes usually takes many years to cause kidney damage. If you have decreased kidney function or protein in your urine (microalbuminuria) from diabetes, there are a few important steps you can take to prevent worsening of your kidney function.
Even small improvements can lower your risk of progressive kidney disease. These steps include:
Achieve good blood pressure control
The target may vary from person to person, but generally is less than 140/90. Taking an ace inhibitor of angiotensin receptor blocking medication can help lower blood pressure and has specific effects on the kidney that protect the kidney from damage caused by diabetes.
Stop smoking if you smoke
It increases risk for renal function deterioration, including diabetic nephropathy.
Maintain a healthy body weight
Getting to and maintaining normal body weight (body mass index under 25) can help with lowering blood pressure and reducing your need for diabetic medications. It also helps with preventing kidney disease.
Control your diabetes
Maintain a goal hemoglobin A1C of less than 7 percent with diet and medications.
Control you cholesterol
Use diet and medications if necessary.
Limit your dietary sodium intake
Keep daily sodium intake under 2000 mg per day. This helps to lower your blood pressure and helps your medication to work more effectively.
Follow up with your nephrologist (kidney specialist)
