Chronic kidney disease is one of the most significant public health challenges facing Sri Lanka today. With 10 to 15 percent of the Sri Lankan population affected – and with a unique form of kidney disease of unknown cause particularly prevalent in farming communities in the north central province – a large and growing number of Sri Lankan patients face the challenge of managing kidney function decline, preventing progression, and in advanced cases, accessing dialysis or transplant.
Chronic kidney disease treatment in India offers Sri Lankan patients access to specialist nephrology care, advanced dialysis support, comprehensive management of kidney disease complications, and kidney transplant evaluation and surgery – at internationally accredited hospitals with coordinated patient support from Colombo.
This guide explains what CKD is, how it progresses, and what treatment options are available for Sri Lankan patients at different stages of the disease.
Why Chronic Kidney Disease Is a Priority Health Issue for Sri Lankan Patients
Sri Lanka carries one of the highest burdens of chronic kidney disease in South Asia. Several factors contribute to this:
- High prevalence of diabetes – affecting approximately 23 percent of the adult population, diabetes is the leading cause of CKD globally and a major driver of kidney disease in Sri Lanka
- High prevalence of hypertension – affecting between 28 and 51 percent of the adult population depending on the region, hypertension is the second leading cause of CKD
- Chronic kidney disease of unknown aetiology (CKDu) – a distinct form of kidney disease affecting farming communities in the north central province of Sri Lanka, particularly in the Polonnaruwa and Anuradhapura districts, where prevalence in some areas exceeds 20 percent of the population. The exact cause of CKDu remains a subject of ongoing research
- Limited dialysis capacity – Sri Lanka’s healthcare system faces significant constraints in dialysis provision, with some reports of patients receiving less frequent dialysis sessions than clinically optimal during periods of resource shortage
For Sri Lankan patients with advanced CKD who are not receiving adequate management or who are approaching end-stage kidney disease, accessing specialist care in India represents a meaningful and increasingly well-supported option.
What Is Chronic Kidney Disease?
Chronic kidney disease is a condition characterised by a gradual, progressive loss of kidney function over a period of months or years. The kidneys’ primary functions – filtering waste products and excess fluid from the blood, regulating blood pressure, balancing electrolytes, and producing hormones that regulate red blood cell production and bone health – are progressively impaired as the disease advances.
Unlike acute kidney injury, which develops rapidly and may be reversible, chronic kidney disease develops slowly. In the early stages, the kidneys may compensate sufficiently that symptoms are minimal or absent. By the time significant symptoms appear, meaningful kidney function has often already been lost.
The defining characteristic of CKD is a reduction in the glomerular filtration rate (GFR) – a measure of how effectively the kidneys are filtering the blood – that persists for more than 3 months.
What Are the Stages of Chronic Kidney Disease?
CKD is classified into five stages based on the estimated glomerular filtration rate (eGFR):
Stage 1 (eGFR 90 or above)
Kidney damage is present – detected by markers such as protein in the urine – but GFR is normal or increased. Most patients have no symptoms. Management focuses on treating the underlying cause and preventing progression.
Stage 2 (eGFR 60-89)
Mild reduction in kidney function. Most patients remain asymptomatic. Risk factor management and monitoring are the priorities.
Stage 3a and 3b (eGFR 30-59)
Moderate reduction in kidney function. Complications including anaemia, bone disease, and blood pressure abnormalities begin to develop. More intensive monitoring and management of complications is required.
Stage 4 (eGFR 15-29)
Severely reduced kidney function. Preparation for kidney replacement therapy – dialysis or transplant – begins. Patients are referred to a nephrologist for transplant evaluation and planning.
Stage 5 – End-Stage Kidney Disease (eGFR below 15)
Kidney function is severely reduced and can no longer sustain life without replacement therapy. Dialysis or kidney transplant is required.
Understanding which stage a patient is at is critical to determining the appropriate treatment approach and the urgency of specialist intervention.
What Causes Chronic Kidney Disease?
The most common causes of CKD in Sri Lankan patients include:
Diabetic Nephropathy
Diabetes is the leading cause of CKD globally. High blood glucose levels cause progressive damage to the small blood vessels within the kidney’s filtering units (glomeruli), gradually reducing their ability to filter effectively. Good blood glucose control significantly slows the progression of diabetic nephropathy.
Hypertensive Nephropathy
High blood pressure damages the blood vessels throughout the kidneys, reducing blood flow and impairing filtration. Blood pressure control is the single most important modifiable factor in slowing CKD progression.
Glomerulonephritis
Inflammation of the kidney’s filtering units, which can be caused by autoimmune conditions, infections, or occur without a clearly identifiable cause. Several types of glomerulonephritis are recognised, each with different management approaches.
Chronic Kidney Disease of Unknown Aetiology (CKDu)
The form of kidney disease disproportionately affecting Sri Lanka’s agricultural communities, particularly in the north central province. CKDu affects patients who do not have the typical risk factors of diabetes or significant hypertension. The cause remains the subject of ongoing scientific investigation, with hypotheses including heavy metal exposure, pesticide use, dehydration, and other environmental factors.
Polycystic Kidney Disease
A genetic condition in which cysts develop within both kidneys, progressively replacing normal kidney tissue and reducing function over time.
Obstructive Uropathy
Long-standing obstruction to urine flow – for example, from an enlarged prostate, kidney stones, or tumour – can cause backpressure damage to the kidneys.
Recurrent Kidney Infections
Repeated episodes of pyelonephritis (kidney infection), particularly in the context of anatomical abnormalities, can cause progressive scarring and function loss.
What Are the Symptoms of Chronic Kidney Disease?
CKD is often described as a silent condition in its early and middle stages, because the kidneys have a significant reserve capacity and symptoms may not appear until function is substantially reduced.
When symptoms do develop, they reflect the kidneys’ failure to perform their normal functions:
Symptoms Relating to Waste Accumulation
- Fatigue and weakness – caused by accumulation of waste products (uraemia) and anaemia
- Nausea, loss of appetite, and vomiting
- Difficulty concentrating and mental fogginess
Symptoms Relating to Fluid Imbalance
- Swelling of the ankles, feet, and legs (oedema)
- Shortness of breath – from fluid accumulation around the lungs
- High blood pressure that is difficult to control
Symptoms Relating to Anaemia
- Persistent fatigue and breathlessness
- Pale skin
- Reduced exercise tolerance
Urinary Symptoms
- Changes in urine output – either reduced or increased depending on the stage and cause
- Frothy urine – an indicator of protein in the urine (proteinuria)
- Blood in the urine (haematuria) – depending on the underlying cause
Bone and Mineral Symptoms
- Bone pain and increased fracture risk – caused by disturbances in calcium, phosphate, and vitamin D metabolism
- Itching – caused by accumulation of phosphate and other substances
How Is Chronic Kidney Disease Diagnosed and Monitored?
CKD is diagnosed and monitored through a combination of blood tests, urine tests, and imaging:
Blood Tests
- Serum creatinine and estimated GFR (eGFR) – the primary measures of kidney function. eGFR is calculated from the serum creatinine together with the patient’s age and sex
- Urea and electrolytes – assess waste accumulation and electrolyte balance
- Full blood count – to assess for anaemia
- Calcium, phosphate, and parathyroid hormone (PTH) – to assess bone mineral metabolism
- Bicarbonate – metabolic acidosis is common in CKD
Urine Tests
- Urine albumin-to-creatinine ratio (UACR) – a sensitive measure of protein leakage into the urine, a key marker of kidney damage and a predictor of CKD progression
- Urine dipstick and microscopy – to assess for blood, infection, and casts
- 24-hour urine collection – for quantification of protein excretion in selected cases
Imaging
- Renal ultrasound – assesses kidney size, structure, and echogenicity, and identifies obstructions, cysts, or tumours
- CT urogram – for detailed assessment of the urinary tract when structural abnormalities are suspected
Kidney Biopsy
In selected cases where the underlying cause of CKD is not clear from clinical and laboratory assessment, a kidney biopsy – taking a small sample of kidney tissue under ultrasound guidance – is performed to identify the specific cause and guide treatment.
What Are the Treatment Options for Chronic Kidney Disease?
Treatment of CKD involves managing the underlying cause, slowing progression, treating complications, and, in advanced stages, preparing for or initiating kidney replacement therapy.
Managing the Underlying Cause
- Blood glucose control for diabetic nephropathy – target HbA1c levels as advised by the treating team
- Blood pressure control – ACE inhibitors or ARBs are the preferred antihypertensive agents in CKD, as they have specific protective effects on the kidney beyond blood pressure lowering
- SGLT2 inhibitors – a class of medication originally developed for diabetes that has demonstrated significant kidney-protective effects in patients with CKD, including those without diabetes. These represent one of the most important recent advances in CKD management
- Treatment of glomerulonephritis – depending on the type, may include immunosuppressive medication, steroids, or specific targeted therapies
Slowing Progression
- Strict blood pressure control targeting below 130/80 mmHg
- Protein restriction in the diet – reducing dietary protein load reduces the filtration demand on the kidneys
- Smoking cessation – smoking accelerates kidney function decline
- Reduction of nephrotoxic medication exposure – including NSAIDs (anti-inflammatory pain medications such as ibuprofen), which should generally be avoided in CKD
Treating Complications
- Anaemia – managed with iron supplementation and, where indicated, erythropoiesis-stimulating agents (ESAs) to stimulate red blood cell production
- Renal bone disease – managed with dietary phosphate restriction, phosphate binders, active vitamin D supplementation, and in some cases calcimimetic agents
- Metabolic acidosis – managed with sodium bicarbonate supplementation
- Fluid overload – managed with dietary sodium and fluid restriction, and diuretic medication
Preparing for Kidney Replacement Therapy
For patients approaching Stage 4 to 5 CKD, planning for kidney replacement therapy begins well before it is urgently needed:
- Transplant evaluation is initiated early to allow time for donor assessment and preparation
- Dialysis access is planned and created – either arteriovenous fistula formation for haemodialysis, or peritoneal dialysis catheter placement
- Patient education on the different modalities of kidney replacement therapy
What Is Dialysis and When Is It Required?
Dialysis is a process that mechanically performs the kidney’s filtration function when the kidneys can no longer do so adequately. It is required when kidney function has declined to the point where waste accumulation, fluid retention, and electrolyte imbalances become life-threatening – generally at Stage 5 CKD (eGFR below 15).
Haemodialysis
Blood is circulated through a dialysis machine that filters waste products and excess fluid, then returned to the body. Typically performed three times per week, with each session lasting 3 to 5 hours. Requires access via an arteriovenous fistula (a surgically created connection between an artery and vein in the arm) or a dialysis catheter.
Peritoneal Dialysis
Uses the patient’s own peritoneal membrane (the lining of the abdominal cavity) as a filter. A dialysis fluid is introduced through a catheter into the abdomen, allowed to dwell for a period, then drained, carrying waste products with it. Can be performed at home, offering greater lifestyle flexibility than haemodialysis.
For Sri Lankan patients who are already on dialysis and wish to be evaluated for kidney transplant, or who require more intensive dialysis management than is currently available to them, Amrita Hospitals’ nephrology team can provide specialist review and management optimisation.
When Is a Kidney Transplant Recommended?
A kidney transplant is the preferred treatment for eligible patients with end-stage kidney disease. Compared to long-term dialysis, a successful kidney transplant offers:
- Better survival outcomes
- Significantly better quality of life
- Freedom from the schedule and physical demands of dialysis
Transplant evaluation is typically initiated at Stage 4 CKD, so that if a living donor is identified, transplant can be performed before dialysis becomes necessary (pre-emptive transplant).
Living Donor Kidney Transplant
A healthy family member or eligible close relative donates one kidney. The donor’s remaining kidney compensates adequately, and long-term outcomes for donors are generally excellent. Living donor transplant is associated with better outcomes than deceased donor transplant and does not involve a waiting period.
Deceased Donor Kidney Transplant
A kidney from a brain-dead donor who has consented to organ donation. Recipients are listed on the transplant waiting list and allocated a kidney based on compatibility and clinical urgency.

Frequently Asked Questions
Can CKD be reversed? In most cases, the damage caused by chronic kidney disease cannot be reversed. However, with appropriate treatment – controlling blood pressure, blood glucose, and other risk factors – progression can be significantly slowed, and in some cases stabilised. Early diagnosis and intervention offer the best opportunity to preserve kidney function.
How often does a CKD patient need to visit the nephrologist? This depends on the stage of CKD. In Stage 1 to 2, annual review may be sufficient if the condition is stable. In Stage 3, review every 3 to 6 months is typical. In Stage 4 to 5, more frequent review – every 1 to 3 months – is standard. Your nephrologist will advise on the appropriate monitoring frequency for your specific situation.
Can Sri Lankan patients on dialysis travel to India for treatment? Yes. Amrita Info Centre Sri Lanka can assist with arranging dialysis sessions at Amrita Hospitals during the patient’s stay in India. Travel while on dialysis requires careful coordination, and our team will advise on the logistics of managing this.
What is the difference between CKD and CKDu? CKD refers to chronic kidney disease broadly, encompassing all causes. CKDu (chronic kidney disease of unknown aetiology) is a specific form of CKD diagnosed in Sri Lankan farming communities where the kidney disease progresses without the presence of the typical causes – diabetes and hypertension – and where the exact cause remains unknown.
Is a kidney transplant possible for patients with CKDu? Yes. Kidney transplant is an appropriate treatment for end-stage kidney disease regardless of the underlying cause, including CKDu. The transplant evaluation process is the same as for other CKD patients. The transplanted kidney does not develop CKDu, making transplant a viable long-term solution for eligible patients.
What lifestyle changes help slow CKD progression? Key lifestyle measures include strict blood pressure control, blood glucose control in diabetic patients, reducing dietary salt and protein intake, staying well hydrated, avoiding NSAIDs and other nephrotoxic substances, stopping smoking, and maintaining a healthy weight. Your nephrologist will provide specific dietary and lifestyle guidance tailored to your stage of CKD.
