Caring for Your Kidneys When You Have Diabetes

Each year, the American Diabetes Association (ADA) releases updated guidelines for diabetes care. Those guidelines are based on the latest research and help medical providers best care for you. Based on the 2022 guidelines, here is what you should know about caring for your kidneys when you have type 2 diabetes.

Monitor your kidney health regularly

With diabetes, 2 main diagnostic tests are used to tell your provider how well your kidneys are working.

Urine albumin test

The first test is called a urine albumin test. The urine albumin test checks the levels of protein in your urine. Higher levels of protein found in your urine are not considered normal and cause concern.

Estimated glomerular filtration rate

The second test is called an eGFR. The eGFR is often done as a blood test and is part of a group of labs called a basic metabolic panel. An eGFR shows how well your kidneys filter waste products out of your body.

A urine albumin test and eGFR should be performed at least every year. If your levels are in concerning ranges, you should have these tests done at least twice a year.1

Know your options to keep your kidneys healthy

Blood sugar and blood pressure

When you have diabetes, protecting your kidneys starts with healthy blood sugar and blood pressure levels. Having stable, healthy levels can slow kidney damage or lower the chance of it happening in the first place.

Your provider will work with you to help keep your blood sugar and blood pressure at safe levels. If you're struggling with your blood sugar levels, a Certified Diabetes Care and Education Specialist (CDCES) can often help.

Proper nutrition

Eating patterns are also important for keeping your kidneys healthy. If you have severe kidney disease (but you're not on dialysis), avoiding high levels of protein is necessary. Registered dietitians are a great resource to help you understand how much protein is safe for you. They're also great at helping you learn how to eat well for all your health conditions, which is often overwhelming for many people.2


Medications can help protect your kidneys as well. For example, if you have kidney disease, using an SGLT-2 inhibitor medication can help slow kidney damage and protect against heart disease. SGLT-2 inhibitors are a group of diabetes medicines that help your body urinate sugar out of your body.

In the U.S., SGLT-2 inhibitors include names like:2

  • Empagliflozin
  • Canagliflozin
  • Dapagliflozin
  • Ertugliflozin

Taking certain medications is not recommended if you don't have kidney disease and your blood pressure is healthy.

Consult with a nephrologist

A doctor who specializes in treating the kidneys is called a nephrologist. You should see a kidney specialist if your eGFR is less than 30 or you have high protein levels in your urine. It's also essential to work with a nephrologist if your kidney health is getting worse faster than your provider expected or your provider isn't sure why you're having kidney problems.

Care for your kidneys

If your kidney health doesn't seem to be getting better after trying different treatment options, ask for a referral to a nephrologist. Making sure your kidney labs are done every year, looking at the results, and asking your doctor to review them with you, are some ways you can stay on top of your kidney health.
