TL;DR
What Is Kidney Disease?
Kidney disease occurs when the kidneys experience structural damage or a progressive decline in function, impairing their ability to filter waste products, excess fluid, and toxins from the bloodstream.
The most common form is Chronic Kidney Disease (CKD), defined as persistent kidney damage or a reduced estimated Glomerular Filtration Rate (eGFR) lasting for three months or longer. Chronic conditions like diabetes and high blood pressure gradually strain the delicate filtering units (nephrons).
Another important form is obesity-related kidney disease (or obesity-related glomerulopathy), where excess body weight places an increased metabolic and physical strain on the kidneys. This hyperfiltration causes scarring over time and accelerates functional loss. Additionally, primary glomerular diseases—most notably IgA Nephropathy (an autoimmune condition where antibody deposits accumulate in the kidneys)—can trigger local inflammation, damage filtering membranes, and lead to progressive CKD.

Kidney Disease Prevalence In Singapore
Kidney disease represents a major public health concern in Singapore. According to national health statistics, approximately 14% of Singaporean adults suffer from Chronic Kidney Disease. Singapore faces one of the highest rates of End-Stage Renal Disease (ESRD) globally, driven significantly by high rates of diabetes and hypertension. Every day, multiple individuals in Singapore suffer from kidney failure and require lifelong kidney replacement therapy (dialysis or kidney transplantation).
What Are The Causes Of Kidney Damage & Risk Factors?
Kidney disease develops due to multiple metabolic, systemic, and genetic causes. Primary risk factors include:
- Diabetes Mellitus: Uncontrolled blood sugar levels damage the delicate blood vessels in the kidneys over time, serving as the leading cause of kidney failure in Singapore.
- High Blood Pressure (Hypertension): Persistent high pressure within the renal blood vessels damages tissue, impairing filtration capacity.
- Obesity: Excess adipose tissue forces the kidneys to filter harder (hyperfiltration) to meet metabolic demands, directly triggering obesity-related kidney disease.
- Glomerular Diseases & IgA Nephropathy: Autoimmune and inflammatory conditions directly target the kidney’s filtering units. IgA Nephropathy is one of the most common forms of primary glomerulonephritis in Singapore and Asia.
- Family History & Genetic Conditions: A family history of renal disease or inherited conditions increases overall susceptibility.
- Smoking & Age: Ageing naturally decreases nephron density, while tobacco use restricts vascular blood flow and accelerates renal damage.
What Are The Symptoms Of Kidney Disease?
In its early stages, kidney disease is often asymptomatic and may go unnoticed. As kidney function declines, waste products and fluid build up in the body, leading to observable symptoms:
- Swelling (Edema): Fluid retention causes noticeable swelling in the legs, ankles, feet, face, or around the eyes.
- Urinary Changes: Changes in frequency, frothy or foamy urine (indicating protein/proteinuria), or dark, rust-coloured urine (blood/haematuria).
- Fatigue & Weakness: Decreased kidney function leads to a buildup of toxins or anaemia, causing persistent tiredness.
- Shortness of Breath: Fluid accumulation in the lungs or severe anaemia can make breathing difficult.
- Nausea & Appetite Loss: Uraemia (build-up of waste products in the blood) can cause persistent nausea, metallic taste, or loss of appetite.
- High Blood Pressure: Poorly functioning kidneys struggle to regulate fluid and pressure, worsening hypertension.
How To Prevent This Condition?
Preventing kidney disease involves controlling underlying metabolic risks and maintaining vascular health:
- Manage Blood Sugar & Pressure: Routine monitoring and strict control of diabetes and hypertension significantly slow or prevent renal damage.
- Maintain a Healthy Weight: Weight management strategies lower the risk of obesity-related kidney disease and reduce renal hyperfiltration.
- Adopt a Balanced Diet: Reducing sodium, processed foods, and excessive protein intake eases the workload on the kidneys.
- Quit Smoking: Stopping smoking preserves vascular health and blood flow to the renal arteries.
- Undergo Regular Screening: Annual blood and urine tests facilitate early detection of CKD or conditions like IgA Nephropathy before irreversible harm occurs.
What Are The Costs Of Screening & Testing For Kidney Disease?
Early screening and diagnostic tests evaluate functional capacity, protein leakage, and structural tissue changes:
| Screening / Diagnostic Test | Function & Description | Estimated Cost (Private Sector)* |
| Blood Tests (Serum Creatinine & eGFR) | Measures kidney filtration efficiency and metabolic waste buildup. | S$50–S$150 |
| Urine Tests (UACR / Proteinuria Screen) | Detects abnormal protein leakage or microhaematuria. | S$30–S$100 |

Which Doctor For Treatment Of Kidney Disease?
Medical professionals involved in managing renal conditions include general practitioners, renal physicians, and vascular surgeons:
- Renal Physician (Nephrologist) – A specialist in kidney health who evaluates, diagnoses, and manages chronic kidney disease, obesity-related renal damage, hypertensive nephropathy, and autoimmune glomerular conditions such as IgA Nephropathy. They also oversee dialysis access planning and long-term renal replacement therapy.
- Vascular Surgeon – Specialises in creating and maintaining vascular access for patients requiring haemodialysis, such as Arteriovenous Fistulas (AVF) or Arteriovenous Grafts (AVG).
- Urologist– A surgical specialist focusing on anatomical issues of the urinary tract, including kidney stones, urinary obstructions, and renal structural abnormalities.
- Transplant Surgeon – Specialises in surgical kidney transplantation for patients with end-stage renal disease.

FAQs
Chronic Kidney Disease (CKD) often progresses gradually without noticeable symptoms during its early stages. Because the remaining healthy nephrons compensate for impaired ones, patients may lose up to 90% of their renal function before severe symptoms like swelling or fatigue appear. Regular blood and urine tests are essential for early detection.
In its early stages, obesity-related kidney disease can be stabilized or improved through structured weight loss, dietary adjustments, and blood pressure control. Reducing body weight lowers renal hyperfiltration strain, helping to prevent progressive scarring and long-term kidney damage.
IgA Nephropathy is an autoimmune kidney disorder where abnormal Immunoglobulin A (IgA) antibodies deposit in the glomeruli (the filtering units of the kidneys). This causes localized inflammation, protein or blood leakage into the urine, and progressive scarring over time. It requires specialized evaluation by a nephrologist to guide treatment and preserve kidney function.
CKD is diagnosed using blood tests to calculate estimated Glomerular Filtration Rate (eGFR) and urine tests to check for protein leakage (urine albumin-to-creatinine ratio). CKD is classified into 5 stages based on eGFR level, ranging from Stage 1 (mild damage with normal eGFR) to Stage 5 (Kidney Failure requiring dialysis or transplantation).
Haemodialysis (HD) involves filtering the patient’s blood through a machine at a dialysis centre typically 3 times a week, requiring a vascular access like an AV fistula. Peritoneal Dialysis (PD) is a home-based continuous or automated exchange treatment that uses the patient’s abdominal lining (peritoneum) to filter waste. A nephrologist helps patients select the option best suited to their lifestyle and medical condition.
