Diabetes and Kidney Health: How to Protect Your Kidneys | Dr. Moxit Shah

Diabetes affects more than blood sugar. Over time, persistently high glucose can damage the kidneys. The important point is that early diabetic kidney disease may have no symptoms, which is why regular screening matters.
How Does Diabetes Affect the Kidneys?
Your kidneys filter waste from the blood. Diabetes can gradually affect the tiny blood vessels and filtration structures inside the kidneys. Early changes may appear as increased albumin in the urine, while kidney filtration can decline later.
Which Kidney Tests Should People With Diabetes Have?
Two routine measurements are particularly important:
- Urine albumin-to-creatinine ratio (UACR): detects abnormal albumin leakage into the urine.
- Estimated glomerular filtration rate (eGFR): estimates how well the kidneys are filtering blood.
The 2026 American Diabetes Association Standards of Care recommend at least annual UACR and eGFR assessment for people with type 2 diabetes, regardless of treatment. For type 1 diabetes, annual assessment is recommended after at least 5 years of diabetes duration.
What Does Albumin in the Urine Mean?
A UACR below 30 mg/g is considered normal to mildly increased. A UACR of 30–299 mg/g is moderately increased, while 300 mg/g or higher is severely increased. Because urine albumin can vary, an abnormal result may need confirmation with repeat testing rather than being interpreted from a single sample.
Can Diabetic Kidney Disease Be Prevented or Slowed?
Kidney protection involves more than one treatment. Good blood glucose control, appropriate blood-pressure management, avoiding smoking, maintaining healthy lifestyle habits, and choosing glucose-lowering medicines with proven kidney or cardiovascular benefits when appropriate can all form part of an individualized treatment plan.
For people with type 2 diabetes and chronic kidney disease, current ADA guidance recommends an SGLT2 inhibitor for appropriate patients with eGFR ≥20 mL/min/1.73 m² to reduce the risk of chronic kidney disease progression and cardiovascular events. Medication selection and dosing should always be individualized.
When Should You See an Endocrinologist?
Specialist assessment can be useful when blood glucose remains difficult to control, kidney tests are abnormal, medications need adjustment because of reduced kidney function, or diabetes treatment needs to balance glucose, cardiovascular and kidney risks.
If kidney function is declining rapidly, urinary albumin is progressively increasing, or eGFR falls below 30 mL/min/1.73 m², nephrology referral should be considered.
Diabetes and Kidney Health: A Simple Checklist
- Check HbA1c as recommended for your individual treatment plan.
- Monitor blood pressure regularly.
- Have UACR and eGFR checked at the appropriate interval.
- Take prescribed diabetes and blood-pressure medicines consistently.
- Ask before using medicines that may be unsuitable with reduced kidney function.
- Avoid smoking and work toward sustainable lifestyle habits.
- Discuss abnormal or changing kidney results with your doctor rather than waiting for symptoms.
