Kidney Disease in India: 29 Data-Backed Insights on Risk, Treatment Costs & Recovery

Kidney disease is becoming an increasingly important health concern in India, affecting millions of people and developing silently until significant kidney damage has already occurred. Conditions such as diabetes, high blood pressure, ageing, and lifestyle-related health issues are contributing to a growing burden of kidney disease across the country¹.

Based on Go Digit General Insurance (Digit) health insurance data for the Calendar year 2025, these 31 insights highlight who may be more vulnerable to kidney disease, the factors that can increase the risk, how treatment patterns vary across different regions, and how long recovery can take. Understanding these trends can help you recognise early warning signs, risk factors and seek timely medical care.

Kidney disease is often called a “silent” condition because many people do not experience obvious symptoms until the disease has already progressed. Yet its impact can be far-reaching, affecting daily life, long-term health, recovery timelines, and healthcare costs.

These insights explore real-world patterns related to kidney disease across India, covering who is most affected, how treatment costs vary, what recovery typically looks like, and the factors that can influence disease severity.

1. Kidney Disease Cases Have Risen Sharply Over the Past Five Years

The number of people seeking treatment for kidney disease has increased steadily in recent years, highlighting the growing burden of kidney-related health conditions. According to Digit, “the number of reported kidney disease cases shows an increasing trend from 2021 to 2025.”

This rise may be linked to an increase in risk factors such as diabetes, high blood pressure, obesity, sedentary lifestyles, and an ageing population. Improved awareness and better diagnostic testing may also be helping more people identify kidney problems earlier than before².

2. Chronic Kidney Disease Accounts for the Majority of Kidney Disease Burden in India

Kidney disease is broadly classified into two main types, Acute Kidney Injury (AKI) and Chronic Kidney Disease (CKD). AKI develops suddenly, often due to severe infections, dehydration, certain medications, or a medical emergency, and may improve with timely treatment. CKD, on the other hand, develops gradually over months or years and is usually linked to long-term conditions such as diabetes and high blood pressure.

Chronic Kidney Disease is the more common and long-lasting form of kidney disease in India, affecting an estimated 8.5% of the population³.

3. People Above 40 Years of Age Should Monitor Kidney Health Regularly

Digit data suggests that the highest number of kidney-related treatment is seen among people aged 42 - 66. This is the age group where long-term health conditions such as diabetes, hypertension, obesity, and heart-related issues often become more common.

Hence, people above 40 should monitor kidney health regularly, especially if they have diabetes, high blood pressure, or heart-related conditions.

4. Senior Citizens (60+ Years of Age) are More Vulnerable to Kidney Disease

The risk of kidney disease tends to increase with age, as kidney function naturally declines over time. According to Digit, people above 60 years of age are among the most affected by kidney disease, making regular health check-ups, kidney function tests, and timely management of existing health conditions especially important for senior citizens.

Older adults are also more likely to have health conditions such as diabetes, high blood pressure, and heart disease, which can further increase the risk of developing kidney disease⁴.

5. Over 70% of Kidney Disease Cases are Seen in Men Compared to Women

Kidney disease can affect both men and women, but certain risk factors such as diabetes, smoking, and lifestyle-related health conditions may increase the risk among men⁵.

Digit data shows that, around 70% of kidney disease cases are seen in men, compared to women, highlighting the importance of regular kidney health screenings and early management of risk factors, especially for men.

6. High Blood Pressure, Diabetes and Heart Disease are a Major Risk Factor for Kidney Disease

Digit findings highlight that high blood pressure, diabetes and heart disease are closely connected with kidney disease. Adults aged 42 - 66 report the highest number of kidney disease cases linked to high blood pressure and diabetes.

Digit data also show that people with kidney disease and additional health conditions spend an average of 14 days in the hospital, highlighting how managing multiple health issues can extend recovery time and increase the need for ongoing monitoring.

7. Bengaluru Reports the Highest Number of Kidney Disease Cases Among Major Indian Cities

Digit findings suggest that Bengaluru reports the highest number of kidney disease cases among major Indian cities, followed by New Delhi, Hyderabad, Gurgaon, and Chennai. This highlights the growing burden of kidney disease in large urban centres and the importance of regular kidney health screening. 

This can be because of rapid urbanisation, sedentary lifestyles, and the growing prevalence of health conditions

8. Nearly 79% of Kidney Disease Cases are Reported from Rural Areas

According to Digit, “nearly 79% of kidney disease cases are reported from rural areas, compared to urban areas.” In many rural areas, limited access to specialist healthcare, lower awareness of kidney disease symptoms, and delays in diagnosis may result in kidney problems being detected at a more advanced stage⁶.

This highlights the importance of improving awareness and encouraging regular health check-ups, especially in rural communities where the disease may go undetected for longer periods.

9. Frequent Urination and Swelling in Feet are Among the First Signs of Kidney Disease

One of the biggest challenges with kidney disease is that symptoms may not appear in the early stages. As kidney function declines, the body may start showing signs such as fatigue, swelling in the feet and ankles, frequent urination (especially at night), difficulty concentrating, loss of appetite, muscle cramps, dry or itchy skin, and persistent high blood pressure⁷.

Because the symptoms of kidney disease can be mild or easy to overlook, many people do not realize they have a kidney problem until significant damage has already occurred.

10. A Simple Blood and Urine Test Can Help Detect Kidney Disease Early

Doctors can diagnose kidney disease using simple tests such as a blood test to measure kidney function (GFR), a urine test to check for protein leakage, and imaging tests like ultrasound when needed³.

Detecting kidney disease early can help slow its progression, prevent complications, and reduce the chances of needing dialysis or a kidney transplant in the future.

11. Most Kidney Disease Cases Progress Gradually Through Five Distinct Stages

Chronic Kidney Disease is not a single condition but a progressive disease that is divided into different stages based on how well the kidneys are filtering waste from the blood. Doctors assess this using the Glomerular Filtration Rate (GFR), a measure of how efficiently the kidneys are working. The lower the GFR, the more severe the kidney damage⁷.

• Stage 1: GFR 90 or above - Kidney function is normal, but there may be early signs of kidney damage.
• Stage 2: GFR 60 – 89 - Mild reduction in kidney function.
• Stage 3: GFR 30 – 59 - Moderate kidney damage and symptoms may start becoming noticeable.
• Stage 4: GFR 15 – 29 - Severe loss of kidney function and increased risk of complications.
• Stage 5: GFR below 15 - Kidney failure, often requiring dialysis or a kidney transplant.

12. Kidney Disease Treatment Requires Long-Term Care Rather Than a One-Time Cure

The treatment for kidney disease depends on its type, stage, and underlying cause. In the early stages, doctors usually recommend lifestyle changes, medications, and regular monitoring to slow down further kidney damage. As the disease progresses, more intensive treatment like dialysis or transplant may be needed⁷.

Early diagnosis and timely treatment can help slow disease progression and improve quality of life.

13. Dialysis-related Treatment Involves Repeated Hospital Visits

Data analysed by Digit indicates dialysis may be needed when the kidneys cannot filter waste and excess fluid properly. For many patients, dialysis is not a one-time procedure but a repeated treatment cycle.

This can affect time, routine, travel, work, and finances. Families should understand the hospital network, cashless availability, and documentation process if dialysis is part of the treatment plan⁴.

14. Kidney Transplant is the Most Effective Treatment for Kidney Failure

When kidney disease progresses to kidney failure, the kidneys are no longer able to effectively remove waste and excess fluids from the body. A kidney transplant involves replacing a failed kidney with a healthy kidney from a donor, allowing many patients to return to a more active and independent life⁸.

For people with advanced kidney disease, a timely transplant can improve quality of life, reduce dependence on dialysis, and support better long-term health outcomes.

15. Kidney Disease Treatment Can Cost Around ₹27,000 on Average

According to Digit data, the average treatment cost for a kidney disease-related hospitalization is around ₹27,000, highlighting the significant financial burden kidney disease can place on individuals and families.

Early detection, regular health check-ups, and managing risk factors such as diabetes and high blood pressure may help reduce both health complications and treatment expenses³.

16. Kidney Disease Hospitalisation Can Cost Around ₹7- 8K Per Day in Room Charges

Digit states that the average daily room cost for kidney disease treatment is around ₹7 - 8K per day. Since kidney disease hospital stays can be longer than many other conditions, room charges alone can become a major part of the total bill.

Hence, expenses such as room rent, nursing care, monitoring, and other hospital services can significantly increase the overall cost of care, especially during longer hospital stays.

17. ICU Treatment for Kidney Disease Can Cost Nearly 68% More Than Regular Hospital Care

Most kidney disease cases can be managed through regular hospitalization, medication, dialysis, and ongoing monitoring. When serious complications such as severe infections, fluid overload, breathing difficulties, or heart-related issues arise, patients may require treatment in the Intensive Care Unit (ICU), where the level of care is much more advanced and resource-intensive⁹.

Digit data reveals that the cost of treating kidney disease in the ICU is approximately 68% higher than non-ICU treatment, highlighting how severe complications can significantly increase medical expenses.

18. Kidney Disease Treatment Costs are Nearly 48% Higher in Private Hospitals

On average, kidney disease treatment cost in private hospitals is nearly 48% higher than the average cost of treatment in public hospitals, as per Digit. It can vary depending on the type of hospital chosen, room charges, specialist consultations, diagnostic tests, and overall treatment expenses.

The higher cost may reflect access to more comprehensive facilities and specialised care and shorter waiting time.

19. Kidney Disease Treatment Costs in Tier 1 Cities is Double than in Tier 2 Cities

The cost of treating kidney disease can vary significantly depending on where you receive treatment. Hospitals in Tier 1 cities often have higher healthcare costs due to factors such as advanced medical facilities, access to super-specialists, higher operational expenses, and the availability of specialized treatment options².

Based on Digit's analysis, kidney disease treatment in Tier 1 cities costs around is approximately double the average treatment cost of in Tier 2 cities. This highlights how the location of treatment can have a major impact on overall healthcare expenses.

20. Kochi Reports the Highest Kidney Disease Treatment Costs in Tier 1 cities

According to treatment patterns observed by Digit, Kochi records the highest kidney disease treatment cost, followed by Visakhapatnam, Meerut, and Vellore. The higher costs in these cities may reflect access to advanced medical infrastructure, specialised kidney care, and treatment for more severe cases, highlighting the importance of being financially prepared for kidney-related healthcare expenses.

These cities also tend to treat more complex and severe kidney disease cases, which may require intensive care, specialised procedures, or longer hospital stays.

21. Severe Kidney Disease Treatment Costs Can Exceed ₹5 Lakh

In severe cases, kidney disease treatment costs can exceed ₹5 lakh as per Digit, highlighting the financial impact that advanced kidney-related complications can have on patients and their families.

The expenses may rise due to prolonged hospital stays, intensive care, dialysis, multiple procedures, and ongoing medical management.

22. Recovery From Kidney Disease Can Take Around 14 - 15 Days on Average

Kidney disease-related hospital stays tend to be much longer than many common infections. Digit's data reveals that the average hospital stays for chronic kidney disease is around 14 – 15 days, suggesting that recovery from severe kidney-related complications can take time and may require consistent medical care and follow-up support.

23. Around 5% of Kidney Disease Patients May Need Intensive Care During Severe Complications

Kidney disease can sometimes become serious enough to require intensive medical care, particularly when complications affect other organs or vital body functions.

In fact, Digit states that around 5 - 6% of people with chronic kidney disease may require ICU care, highlighting ICU may be needed if the patient develops severe complications such as fluid overload, very high blood pressure, infection, breathing difficulty, electrolyte imbalance, or other organ-related concerns.

24. Severe Kidney Disease Cases May Require 7 Days or More of Intensive Medical Care

Patients may need 7+ days of hospital care intensive monitoring and treatment to manage severe kidney issues such as fluid imbalance, infections, breathing difficulties, or complications affecting the heart and other organs.

ICU treatment may include close monitoring of fluids, blood pressure, oxygen levels, infection markers, dialysis-related support, and other critical parameters¹⁰.

25. More Than 56% of Kidney Disease Patients May Require Follow-Up Treatment or Ongoing Care After Initial Treatment

Kidney disease is a long-term condition that often requires continuous monitoring and follow-up care, even after a patient leaves the hospital.

According to Digit data, 56% of kidney disease patients require additional care or follow-up treatment after their initial discharge, highlighting that kidney disease management does not end with one round of treatment and often requires long-term medical attention

26. Reimbursement Claims are 11% More Than Cashless Claims

Digit claims data suggests that reimbursement-based claims are almost 11% higher than cashless treatments, suggesting that many kidney disease patients may still be seeking care outside network hospitals or facilities offering cashless services.

However, cashless health insurance claim is generally a simpler and more convenient process, as it reduces the need for large upfront payments and extensive claim paperwork during treatment.

27. Kidney Disease Affects Relatively Few People, but the Health and Financial Impact Can Be High

At Digit, kidney disease accounts for less than 1% of total health claims. However, this does not mean the disease has a small impact. Kidney disease can involve long hospital stays, repeat claims, dialysis, transplant-related care, and lifelong monitoring.

So, even if the claim volume is not very high, the personal and financial impact on affected families can be significant. Hence, having a health insurance can help provide access to timely treatment and offer financial protection against the high and often recurring costs associated with managing kidney disease.

28. Do not ignore swelling, low urine output, or unusual tiredness

Kidney disease symptoms may not show up initially. However, swelling in the feet or face, reduced urine output, foamy urine, high blood pressure, nausea, fatigue, breathlessness, and loss of appetite can all be warning signs³.

These symptoms should not be ignored, especially if they continue or appear along with diabetes or hypertension.

29. Many Kidney Disease Cases Can Be Prevented Through Early Lifestyle Changes

Taking preventive steps early can help protect kidney function and reduce the risk of long-term complications. Few preventive methods can significantly reduce the risk of developing kidney disease or slow its progression if detected early⁷.

• Maintaining healthy blood pressure and blood sugar levels
• Staying physically active
• Drinking enough water
• Eating a balanced diet,
• Avoiding tobacco and smoking
• Getting regular health check-ups

Kidney disease is a growing health concern that can affect people across different age groups, regions, and lifestyles. It is often linked to common health issues such as diabetes, high blood pressure, and heart disease, making early detection and regular health monitoring critical for preventing serious complications. Longer hospital stays, the need for ongoing treatment, ICU admissions in severe cases, dialysis, and even kidney transplants can increase both the physical and financial burden on patients and their families. 

Recognising risk factors, paying attention to early warning signs, undergoing regular kidney function tests, and managing underlying conditions such as diabetes and hypertension can help reduce the risk of advanced kidney damage.
