Many people with diabetes focus only on sugar readings — but high sugar over years quietly damages the kidney's filters. This is called diabetic kidney disease, and in its early stages it causes no pain and no symptoms.
Two tests every diabetic needs every year
- Urine albumin-creatinine ratio (UACR) – detects small protein leaks, the earliest sign.
- Serum creatinine with eGFR – shows how well the kidneys are filtering.
Warning signs (later stage)
- Frothy urine
- Swelling of feet, ankles or face
- Rising BP that is hard to control
- Tiredness, poor appetite, itching
How to protect your kidneys
- Keep sugar (HbA1c) and BP at targets advised by your doctor
- Avoid painkillers (NSAIDs) and unprescribed supplements
- Stop smoking, stay active, limit salt
- Ask your doctor about modern kidney-protective medicines
Early detection can slow or even stop progression. If your reports show protein in urine or rising creatinine, consult a nephrologist.
