Quick answer. Diabetic kidney disease (diabetic nephropathy) is the leading cause of kidney failure in Singapore, driving a large share of new dialysis cases. It is detected early with a urine albumin-to-creatinine ratio (ACR) and blood tests, and its progression can be slowed by controlling blood sugar and blood pressure and using kidney-protective medicines such as SGLT2 inhibitors.

Diabetes is the single biggest cause of kidney failure in Singapore. Singapore has one of the highest rates of diabetes-related kidney failure in the world, and diabetic nephropathy accounts for roughly two in three new dialysis patients.
The good news is that diabetic kidney disease is largely preventable and treatable when caught early. Regular screening and modern medicines can dramatically slow, and sometimes prevent, progression to kidney failure.
At a glance
| What | Why it matters | General target |
|---|---|---|
| Urine ACR (albumin-to-creatinine ratio) | Detects early protein leak before symptoms | Lower is better; persistent rise needs action |
| eGFR (from blood creatinine) | Estimates overall kidney filtering | Watch for decline over time |
| Blood pressure | High BP speeds kidney damage | Often around 130/80, individualised |
| HbA1c (blood sugar control) | Poor control accelerates damage | Individualised, often around 7% |
How diabetes damages the kidneys
High blood sugar over many years injures the tiny filtering units (glomeruli) in the kidneys. The first measurable sign is often small amounts of the protein albumin leaking into the urine (albuminuria), long before any symptoms appear. Over time, filtering capacity (eGFR) falls and, if uncontrolled, can progress to kidney failure requiring dialysis or transplant. High blood pressure, which commonly accompanies diabetes, accelerates the damage.
Why screening matters – the urine ACR test
Diabetic kidney disease is usually silent in its early, most treatable stages. That is why people with diabetes are advised to have regular screening:
- Urine albumin-to-creatinine ratio (ACR): a simple urine test that detects early protein leak.
- eGFR: calculated from a blood creatinine test to estimate kidney function.
These are typically checked at least once a year. Detecting a rising ACR early allows treatment to start before significant, irreversible damage occurs.
Slowing progression: lifestyle and blood sugar
Foundational steps to protect the kidneys include:
- Good blood sugar control (HbA1c target individualised with your doctor).
- Tight blood pressure control.
- Stopping smoking, staying physically active and maintaining a healthy weight.
- A balanced diet, often with reduced salt; a dietitian can tailor advice, especially as kidney function changes.
Kidney-protective medicines
Several classes of medicine protect the kidneys beyond their effect on sugar or blood pressure:
- ACE inhibitors or ARBs: blood pressure medicines that reduce protein leak and slow decline.
- SGLT2 inhibitors (e.g. dapagliflozin): large clinical trials have shown they reduce the risk of kidney failure and slow the decline in kidney function in people with chronic kidney disease. They are now a cornerstone of treatment for diabetic kidney disease.
- Other agents such as certain non-steroidal mineralocorticoid receptor antagonists may be added in selected patients.
Always take these only as prescribed; your doctor will check kidney function and potassium when starting or adjusting them.
Living well and getting support in Singapore
People with diabetes and kidney disease in Singapore can be enrolled in the Chronic Disease Management Programme (CDMP), allowing MediSave to help pay for outpatient care of diabetes, hypertension and related conditions. Healthier SG and polyclinic teams support long-term management and regular screening. Ask your GP or polyclinic about coordinated chronic disease care.
When to see a nephrologist
See your doctor or ask for a referral to a kidney specialist (nephrologist) if you have: a persistently raised or rising urine ACR, a falling eGFR or rapidly worsening kidney function, significant protein in the urine, difficult-to-control blood pressure, or unexplained swelling of the legs or around the eyes. Seek urgent care for severe breathlessness, marked reduction in urine, or symptoms of very high potassium such as muscle weakness or palpitations.
What to expect at your kidney check
Screening for diabetic kidney disease is quick and usually part of routine diabetes care. You give a urine sample for the albumin-to-creatinine ratio (ACR) and have a blood test for creatinine, from which your eGFR is calculated. Your blood pressure and HbA1c are also checked. Because a single raised ACR can be affected by infection, exercise or fever, your doctor may repeat it to confirm a persistent rise before changing treatment. Bring a list of your current medicines, including any over-the-counter painkillers and supplements, and your recent home blood pressure and glucose readings if you keep them.
Self-management at home
Day-to-day habits strongly influence how the disease progresses. Work towards your individualised blood sugar and blood pressure targets, take medicines consistently, and check readings at home if advised. Reduce salt, which helps blood pressure and swelling, and ask about a kidney-friendly eating pattern, especially as kidney function changes; a dietitian can tailor advice. Stay active, maintain a healthy weight, and stop smoking. Avoid regular use of non-steroidal anti-inflammatory painkillers such as ibuprofen, and check with a pharmacist before new remedies or supplements. Stay hydrated, and during illness with vomiting or diarrhoea, ask your doctor whether any medicines should be paused temporarily.
Costs and chronic disease support in Singapore
Both diabetes and chronic kidney disease are among the conditions covered under the Chronic Disease Management Programme (CDMP), which allows MediSave to help pay for outpatient care of these conditions for those enrolled. Healthier SG and polyclinic teams support long-term management and regular screening, and eligible Singapore Citizens and Permanent Residents receive subsidised rates at public clinics. Ask your GP or polyclinic how to enrol and what MediSave can be used for, as limits and eligibility apply. A medical social worker can help if cost is a concern.
Questions to ask your doctor
- What are my latest ACR and eGFR, and how have they changed over time?
- What are my personal blood sugar and blood pressure targets?
- Would a kidney-protective medicine such as an SGLT2 inhibitor be suitable for me?
- Which painkillers and supplements should I avoid?
- When should I be referred to a nephrologist?
Common questions
Can diabetic kidney disease be reversed?
Early damage may stabilise or improve with good control of blood sugar and blood pressure and kidney-protective medicines, but established scarring is harder to reverse. Catching it early gives the best chance of preserving function.
Why do I need a urine test if I feel fine?
Diabetic kidney disease is usually silent in its early, most treatable stages. The urine ACR can detect protein leak long before symptoms appear, allowing treatment to start sooner.
Are SGLT2 inhibitors safe for the kidneys?
Large trials show these medicines reduce the risk of kidney failure and slow decline in many people with chronic kidney disease. Your doctor checks kidney function and adjusts treatment to use them safely.
