Chronic kidney disease (CKD) is a growing health concern in Singapore. An estimated 14% of Singapore residents were affected by CKD in 2022, up from 9% just two years earlier. Projections also suggest that up to one in four people in Singapore may develop CKD by 2035.
Rising rates of diabetes and high blood pressure are major contributors to the increasing burden of kidney disease. CKD often develops gradually and may not cause symptoms in the early stages, making early detection especially important.
With timely diagnosis, lifestyle changes, and appropriate treatment, it may be possible to slow disease progression and reduce the risk of complications such as kidney failure.
What Is Chronic Kidney Disease?
Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys gradually lose their ability to function effectively over time. The kidneys play a vital role in filtering waste products, excess fluids, and toxins from the bloodstream. This process is carried out through tiny filtering units called glomeruli. When kidney function declines, waste can build up in the body, potentially leading to complications affecting blood pressure, bone health, heart function, and overall well-being.
Chronic kidney disease is classified into five stages based on kidney function. Blood tests measuring creatinine levels and estimated glomerular filtration rate (eGFR) are used to assess severity. Stage 1 represents mild kidney damage with normal or high kidney function, while Stage 5 is known as end-stage kidney disease (ESKD), where kidney function is severely reduced and advanced CKD treatment such as dialysis or transplant may be required.
What Are the Symptoms of Chronic Kidney Disease (CKD)?
Chronic Kidney Disease (CKD) may not cause noticeable symptoms in the early stages. As kidney function declines, waste products and excess fluid can build up in the body, leading to symptoms such as:
What Are the Causes of Chronic Kidney Disease?
CKD can develop when medical conditions or long-term damage affect the kidneys over time. Common causes include:
Diabetes
Diabetes is one of the leading causes of CKD. High blood sugar levels can damage the small blood vessels in the kidneys, reducing their ability to filter waste effectively.
High Blood Pressure
High blood pressure can damage the blood vessels in the kidneys over time, leading to scarring and reduced kidney function.
Glomerulonephritis
Glomerulonephritis is the inflammation of the kidney’s filtering units (glomeruli), which can lead to scarring and long-term kidney damage.
Polycystic Kidney Disease
Polycystic kidney disease is a genetic condition where fluid-filled cysts grow in the kidneys, gradually affecting kidney function.
Recurrent Kidney Infections
Repeated kidney infections can cause scarring and long-term damage to the kidneys, which may lead to CKD over time.
Long-Term Use of Certain Medications
Frequent or prolonged use of certain medications, especially painkillers such as non-steroidal anti-inflammatory drugs (NSAIDs), may damage the kidneys.
Severe Muscle Breakdown (Rhabdomyolysis)
Rhabdomyolysis is a condition where damaged muscle tissue releases harmful substances into the bloodstream, which can injure the kidneys.
Who Is at Risk of CKD and When Should You See a Specialist?
Certain individuals may have a higher risk of developing chronic kidney disease (CKD), even without symptoms. You should consider seeing a doctor for kidney screening if you have the following risk factors:
Older Age
The risk of CKD increases with age, especially in individuals over 50, as kidney function naturally declines over time.
Family History
A family history of CKD or inherited kidney conditions, such as polycystic kidney disease, may increase the risk of developing kidney disease.
Obesity
Being overweight or obese places additional strain on the kidneys and increases the risk of conditions such as diabetes and high blood pressure, which can contribute to CKD.
Smoking
Smoking damages blood vessels and reduces blood flow to the kidneys, which may accelerate kidney damage over time.
Cardiovascular Disease
People with heart disease, stroke, or other cardiovascular conditions may have a higher risk of CKD due to the close relationship between heart and kidney health.
How Is Chronic Kidney Disease (CKD) Diagnosed?
CKD is diagnosed using blood tests, urine tests, and imaging studies to assess kidney function and identify possible causes.
Blood Tests
Blood tests help assess how well the kidneys are functioning.
Serum creatinine
Creatinine is a waste product that is normally removed by the kidneys. Higher creatinine levels may suggest the kidneys are not functioning properly.
Estimated Glomerular Filtration Rate (eGFR)
The eGFR shows how well the kidneys are filtering waste from the blood. A lower eGFR may indicate reduced kidney function, helping doctors determine the stage of CKD.
Urine Tests
Urine tests help detect signs of kidney damage, such as protein or blood in the urine.
Urinalysis (Spot Urine Test)
Checks for the presence of blood, protein, glucose, and signs of infection in the urine. Protein in the urine (proteinuria) is an important early indicator of kidney damage.
24-Hour Urine Collection
Measures the total amount of protein and other substances excreted in urine over a full day, providing a more detailed assessment of kidney function in certain cases.
Imaging Tests
Imaging tests help assess the structure of the kidneys and urinary tract.
Ultrasound Scan
A non-invasive test that uses sound waves to assess kidney size, shape, and structure, and can detect blockages, cysts, or abnormalities.
CT Scan (Computed Tomography)
Provides more detailed cross-sectional images of the kidneys and urinary tract, useful for identifying stones, tumours, or structural issues.
MRI Scan (Magnetic Resonance Imaging)
Used in selected cases to obtain highly detailed images of kidney tissue and surrounding structures without radiation exposure.
What Are the Treatment Options for Chronic Kidney Disease (CKD)?
Treatment for CKD depends on the stage of disease and underlying cause. The aim is to manage symptoms, reduce complications, and help preserve kidney function.
Treatment options for CKD may include:
Lifestyle Modifications
Lifestyle changes form the foundation of early CKD management and play a key role in slowing disease progression.
Quitting smoking to reduce further damage to blood vessels and kidneys
Following a kidney-friendly diet (such as reducing salt intake and controlling protein consumption)
Maintaining a healthy body weight to reduce strain on the kidneys
Engaging in regular physical activity to support overall cardiovascular and metabolic health
These changes are essential components of long-term chronic kidney disease treatment and can significantly help preserve kidney function.
Medications
Medications may be prescribed to help slow CKD progression and manage related conditions, including:
Antihypertensive medications
to control high blood pressure
Medications to manage blood sugar levels
in diabetes
Cholesterol-lowering medications
to reduce cardiovascular risk
Diuretics
to help manage fluid retention and swelling
Dialysis
When Chronic Kidney Disease (CKD) progresses to advanced stages and kidney function is no longer sufficient to sustain the body, dialysis may be required. Dialysis is a life-supporting treatment that helps remove waste products, toxins, and excess fluid from the blood.
The two main types of dialysis are:
Haemodialysis
Blood is filtered through a dialysis machine outside the body
Peritoneal Dialysis
The lining of the abdomen is used as a natural filter to clean the blood internally
Dialysis helps manage symptoms such as fatigue, nausea, breathlessness, swelling, and fluid overload, improving quality of life in advanced kidney disease.
Kidney Transplant
A kidney transplant may be considered when kidney function has severely declined or failed. In this procedure, a healthy kidney from a donor is surgically placed into the patient’s body to help take over the function of the damaged kidneys.
For suitable patients, a kidney transplant may offer better quality of life and greater dietary flexibility compared to long-term dialysis. However, it requires lifelong medical follow-up and medications to reduce the risk of organ rejection.
How to Prevent Chronic Kidney Disease
While not all cases of CKD can be prevented, certain steps may help reduce the risk of kidney damage and support overall kidney health.
Preventive measures include:
Exercising regularly Avoiding smoking Controlling diabetes and high blood pressure Maintaining a healthy weight and balanced diet Attending regular health screenings, especially for individuals with risk factors Limiting long-term or excessive use of certain medications, such as painkillers (NSAIDs) Early detection through routine blood and urine tests can help identify kidney problems early and allow timely treatment to reduce the risk of disease progression.
Chronic Kidney Disease (CKD) vs. Acute Kidney Injury (AKI)
Both chronic kidney disease (CKD) and acute kidney injury (AKI) affect kidney function, but they differ in how quickly they develop, their causes, and treatment approach. Understanding the differences can help patients recognise when kidney problems may require urgent medical attention or long-term management.
| Feature | Chronic Kidney Disease (CKD) | Acute Kidney Injury (AKI) |
|---|---|---|
| Onset | Develops gradually over months or years | Develops suddenly over hours or days |
| Progression | Usually worsens slowly over time | Rapid decline in kidney function |
| Reversibility | Usually not reversible, but progression may be slowed | May improve if treated early |
| Common Causes | Diabetes, high blood pressure, glomerulonephritis | Severe infections, dehydration, medications |
| Treatment | Long-term management and monitoring | Treating the underlying cause |

Frequently Asked Questions About Chronic Kidney Disease (CKD)
Chronic kidney disease is increasingly common in Singapore, with a growing number of individuals affected due to rising rates of diabetes and high blood pressure. Many people may have early-stage CKD without knowing it, as symptoms often do not appear until the condition has progressed. Regular screening is important, especially for those at higher risk.
Dietary recommendations depend on the stage of CKD, but generally include limiting salt, processed foods, and excessive protein intake. Some patients may also need to monitor potassium and phosphorus levels. A personalised diet plan is often part of chronic kidney disease treatment.
Yes, CKD can impact overall health and increase the risk of complications such as heart disease, anaemia, bone disorders, and fluid imbalance. Proper CKD treatment and regular follow-up help reduce these risks.
CKD is generally not reversible, especially in later stages. However, early treatment and lifestyle changes may help slow disease progression and reduce complications.
