Chronic Kidney Disease: Causes, Symptoms, Stages, Treatment and Cost in India

Chronic kidney disease (CKD) is one of the most common long-term illnesses in the world, and it is rising quickly across Africa, the Middle East and South Asia because of the growth of diabetes and high blood pressure. Many people do not know they have it, because the kidneys can lose a large part of their function before any symptoms appear. The good news is that CKD that is picked up early can often be slowed down with medicines and lifestyle changes, and even when the kidneys fail, dialysis and kidney transplantation allow people to live full and productive lives. India is one of the leading destinations for nephrology care and kidney transplantation, with experienced teams and costs that are a fraction of those in Western countries.

What is Chronic Kidney Disease?

The two kidneys filter waste products and extra fluid from the blood, balance salts and minerals, control blood pressure, keep bones healthy and help produce red blood cells. Chronic kidney disease means that the kidneys have been damaged, or their filtering capacity has been reduced, for three months or longer. The damage is usually gradual and permanent, but the speed at which it progresses can be changed with treatment.

Doctors measure kidney function using the estimated glomerular filtration rate (eGFR), calculated from a blood creatinine test, together with the amount of protein (albumin) leaking into the urine. CKD is divided into five stages:

Causes and Risk Factors

CKD is usually the result of another illness that damages the kidneys over many years. The most important causes are:

• Diabetes - the leading cause of kidney failure worldwide. Diabetes rates are particularly high in the Gulf countries, and are rising fast in Africa and South Asia.
• High blood pressure - both a cause and a consequence of CKD. Hypertension is very common in sub-Saharan Africa and often goes untreated for years.
• Glomerulonephritis - inflammation of the kidney filters, sometimes linked to infections or immune diseases such as lupus.
• Polycystic kidney disease and other inherited conditions.
• Infections - HIV-associated kidney disease, hepatitis B and hepatitis C can all affect the kidneys, and these infections are more common in parts of Africa and Central Asia.
• Sickle cell disease - common in West and Central Africa and parts of the Middle East, it can damage the kidneys over time.
• Kidney stones and urinary blockage - repeated stones, an enlarged prostate or narrowing of the urinary tract can cause back-pressure damage.
• Long-term use of painkillers (NSAIDs), certain herbal or traditional remedies, and some other medicines.

Other risk factors include obesity, smoking, older age, a family history of kidney disease, heart disease, and being of African or South Asian ancestry, as these groups have a higher risk of kidney failure.

Symptoms of Chronic Kidney Disease

In stages 1 to 3 most people feel completely well. Symptoms usually appear only when function is significantly reduced. They may include:

• Tiredness, weakness and shortness of breath (often due to anaemia)
• Swelling of the ankles, feet, hands or face
• Passing more or less urine than usual, or needing to urinate at night
• Foamy or frothy urine (a sign of protein) or blood in the urine
• Loss of appetite, nausea, vomiting and weight loss
• Itchy, dry skin and muscle cramps
• Difficulty sleeping and poor concentration
• High blood pressure that is difficult to control

Warning signs that need urgent medical attention: severe breathlessness or difficulty lying flat, chest pain, confusion or drowsiness, very little or no urine, seizures, or an irregular heartbeat (which can be caused by a dangerously high potassium level).

How is CKD Diagnosed?

Because CKD is often silent, anyone with diabetes, high blood pressure or a family history of kidney disease should be tested at least once a year. Common tests include:

• Serum creatinine and eGFR - to measure how well the kidneys are filtering.
• Urine albumin-to-creatinine ratio (ACR) and urine routine examination - to detect protein and blood.
• Blood tests for haemoglobin, potassium, sodium, calcium, phosphate, parathyroid hormone (PTH), vitamin D and bicarbonate.
• Ultrasound of the kidneys - to check their size and look for cysts, stones or blockage.
• Kidney biopsy - a small sample of kidney tissue is examined in selected patients to find the exact cause, especially in glomerulonephritis.

Treatment Options for Chronic Kidney Disease

1. Slowing down the disease

In the early stages the aim is to protect remaining kidney function. This includes strict control of blood sugar and blood pressure, and the use of medicines such as ACE inhibitors or ARBs, which reduce protein leakage. Newer medicines called SGLT2 inhibitors (for example dapagliflozin and empagliflozin) have been shown in large international trials to slow the progression of CKD, both in people with and without diabetes, and are widely available in India. Your nephrologist will also review all your medicines and stop any that may harm the kidneys.

2. Treating complications

As CKD advances, doctors treat anaemia (with iron and erythropoietin injections), bone and mineral problems (with phosphate binders, vitamin D and, if needed, removal of overactive parathyroid glands through parathyroidectomy), fluid overload, acidosis and high potassium. A renal dietitian advises on salt, potassium, phosphate, protein and fluid intake.

3. Dialysis

When the kidneys fail (usually stage 5), dialysis takes over the job of cleaning the blood.

• Haemodialysis - the blood is filtered through a machine, usually three times a week for about four hours per session. The best long-term access is an AV fistula, a connection between an artery and a vein in the arm created by a vascular surgeon, ideally several months before dialysis is needed.
• Peritoneal dialysis (PD) - a soft tube is placed in the abdomen and special fluid is used to remove waste. PD can be done at home, which suits many international patients who return to areas with limited dialysis centres.

4. Kidney transplantation

For most suitable patients, a kidney transplant offers the best quality of life and survival. In India, transplants are mainly performed from living related donors (such as a parent, sibling, spouse or child). For foreign nationals, Indian law (the Transplantation of Human Organs and Tissues Act) requires the donor to be a close relative, with documents proving the relationship verified by the embassy and the hospital's authorisation committee. Leading Indian centres also perform ABO-incompatible transplants (when blood groups do not match) and laparoscopic donor nephrectomy, which means a quicker recovery for the donor.

5. Conservative kidney management

For some elderly or very frail patients, a planned approach focused on symptom control and quality of life, without dialysis, may be chosen after careful discussion with the family.

Living with CKD and Prevention

Many people with CKD lead active lives for many years. The following steps help protect the kidneys:

• Keep blood pressure at the target advised by your doctor (often below 130/80 mmHg).
• Control blood sugar if you have diabetes, and check HbA1c regularly.
• Reduce salt, avoid processed foods and follow your dietitian's advice on potassium and phosphate.
• Stop smoking, stay active and keep a healthy weight.
• Avoid over-the-counter painkillers such as ibuprofen and unregulated herbal products.
• Get vaccinated against hepatitis B, influenza and pneumococcus as advised.
• Attend regular follow-up and blood tests, even when you feel well.

After a kidney transplant, patients must take anti-rejection medicines every day for life and have regular blood tests. Most can return to work and normal activities within two to three months.

Frequently Asked Questions

Can chronic kidney disease be cured?

CKD usually cannot be reversed, but its progression can often be slowed or even stopped with good control of blood pressure, blood sugar and the right medicines. Some causes, such as a urinary blockage or certain types of glomerulonephritis, can improve with treatment.

At what stage of CKD is dialysis needed?

Dialysis is usually started in stage 5, when eGFR falls below about 15, but the decision is based on symptoms and blood results rather than a number alone. Some patients start earlier because of fluid overload or high potassium.

How long can a person live on dialysis?

Many patients live for many years on dialysis, depending on their age and other illnesses such as diabetes or heart disease. A successful kidney transplant usually offers longer survival and a better quality of life than staying on dialysis.

Who can donate a kidney to a foreign patient in India?

For international patients, the donor must be a close blood relative or spouse, and the relationship must be proven with official documents and approved by the hospital's transplant authorisation committee. Commercial or unrelated donation is not permitted under Indian law.

How long do I need to stay in India for a kidney transplant?

Usually about 6 to 8 weeks in total: around 1 to 2 weeks for donor and recipient evaluation and paperwork, 7 to 10 days in hospital after surgery, and 3 to 4 weeks of close follow-up before flying home.

What is the cost of dialysis in India?

Haemodialysis at a reputed private hospital in Delhi NCR typically starts at around $45 per session, excluding medicines such as erythropoietin. Costs are lower at standalone dialysis centres.

Can I travel to India if I am already on dialysis?

Yes. Your dialysis sessions can be booked in advance at the treating hospital or a nearby centre, so you do not miss any treatment during your stay. Share your latest dialysis prescription and reports with us before you travel.

What foods should a CKD patient avoid?

This depends on the stage and blood results, but most patients should limit salt, processed and fast foods, and colas. Some need to limit high-potassium foods (such as bananas, oranges, potatoes and tomatoes) and high-phosphate foods. Always follow a renal dietitian's personalised plan.
