Diabetic Kidney Disease

Overview

Over years, poorly controlled diabetes can damage the small filtering units of the kidneys, a condition called diabetic kidney disease (diabetic nephropathy). It develops silently — there are no symptoms until a late stage — which is why regular screening of kidney function is essential for everyone with diabetes. Caught early, kidney damage can often be slowed or halted with the right treatment.

This page is the overview of diabetic kidney disease as a condition. For the specific tests that detect it early, see Urine Albumin-to-Creatinine Ratio (ACR) and Albuminuria / Microalbuminuria, and for broader kidney care see our Kidney Health service.

How diabetes damages the kidneys

Each kidney contains about a million tiny filters called nephrons. Persistently high blood sugar damages the small blood vessels supplying these filters, causing them to leak protein into the urine and, over time, to lose their filtering ability. High blood pressure accelerates this damage considerably, which is why controlling both sugar and blood pressure is central to protecting the kidneys.

Stages of kidney involvement

Kidney damage from diabetes progresses in stages. The earliest sign is a tiny leak of albumin into the urine (microalbuminuria), often years before blood tests of kidney function change. If unaddressed, the leak increases and the filtering capacity (eGFR) gradually falls. The earlier the stage at which it is caught, the more that can be done to slow or stop progression.

How we screen for it

• Urine test for albumin (ACR) — the earliest sign of kidney leak.
• Blood test for kidney function (creatinine and eGFR).
• Blood pressure control, a key protector of the kidneys.
• Regular monitoring at intervals set by your risk level — at least annually.

Protective treatment

When early kidney changes are found, treatment focuses on protecting the filters from further damage:

• Tightening blood sugar control to reduce ongoing injury.
• Controlling blood pressure, often with specific medicines that also reduce protein leak.
• Avoiding medicines that can harm the kidneys, including some painkillers.
• Dietary adjustments where appropriate, such as moderating salt and, in later stages, protein.
• Regular retesting to confirm the leak is improving or stable.

How we help

Dr. Nayak includes kidney screening as a routine part of diabetes care, identifies early signs of damage before they cause symptoms, and starts protective measures — blood pressure and sugar control, specific medicines, and diet adjustments — to preserve kidney function for the long term. Where damage is more advanced, care is coordinated with timely referral. Consultations are available in-clinic in Bhubaneswar and over teleconsultation.
