Chronic Kidney Disease (CKD) is an escalating health concern in India, with studies indicating a high and rising prevalence across urban and rural populations. CKD often progresses silently, earning it the moniker of a “silent killer,” as symptoms become apparent only in advanced stages. This lack of early warning makes CKD a critical public health issue, compounded by its association with diabetes, hypertension, and lifestyle factors prevalent in India.
Let’s understand what is chronic kidney disease, the stages, its impact an dhow to combat it.
What is Chronic Kidney Disease?
Chronic Kidney Disease (CKD) is a condition where the kidneys gradually lose their ability to filter waste and excess fluids from the blood. This damage often occurs over a long period, typically due to conditions like diabetes, high blood pressure, and heart disease. In its early stages, CKD may not show obvious symptoms, making it difficult to detect.
If left untreated, it can lead to kidney failure, requiring dialysis or a transplant. With the growing prevalence of risk factors in India, CKD is becoming a major health concern, emphasising the need for early diagnosis and better awareness.
One of the leading studies on CKD in India highlights the country’s unique risk profile. Diabetes and hypertension, highly prevalent in Indian populations, are major drivers of kidney damage. The CKD prevalence in India is estimated to be between 10% and 13% of the general population, with millions requiring treatment for end-stage renal disease (ESRD). (Source: ScienceDirect )
Alarmingly, a significant portion of affected individuals remain undiagnosed until irreversible damage has occurred. This highlights the need for greater awareness and routine screening, especially among high-risk groups.
Understanding the stages of Chronic Kidney Disease (CKD)
Chronic Kidney Disease (CKD) progresses through several stages, each reflecting the degree of kidney function loss. Identifying the CKD stages early can help in managing the disease and preventing further complications.
Stage 1: Kidney Damage with Normal or High GFR (Glomerular Filtration Rate)
In this stage, the kidneys are still functioning normally, or the GFR is above 90, but there is detectable kidney damage, often shown by protein or blood in the urine. Early detection is key to slowing down progression.
Stage 2: Mild Decrease in Kidney Function (GFR 60-89)
The kidneys are starting to lose some function, but the decrease is mild. Routine testing can help monitor changes, and managing risk factors like high blood pressure or diabetes is important at this stage.
Stage 3: Moderate Decrease in Kidney Function (GFR 30-59)
In stage 3, kidney function is significantly reduced. Symptoms may start to appear, such as fatigue, swelling, or changes in urination. It’s critical to manage kidney health with medications and lifestyle changes to prevent further decline.
Stage 4: Severe Decrease in Kidney Function (GFR 15-29)
At this stage, kidney function is severely impaired, and symptoms such as swelling, nausea, and shortness of breath may become more pronounced. Dialysis or a kidney transplant may be discussed as options for future treatment.
Stage 5: Kidney Failure (GFR below 15)
This is the final stage of CKD, also known as end-stage renal disease (ESRD). Kidney function is almost completely lost, and dialysis or a kidney transplant is necessary to sustain life.
Early detection and management are essential at every stage to slow the progression of CKD. Regular checkups and lifestyle changes can make a significant difference in how the disease progresses.
Impact of urbanisation and lifestyle on CKD prevalence in India
Urbanisation and lifestyle changes have exacerbated the CKD burden in India. Risk factors for chronic kidney disease include diets high in salt, sugar, and processed foods, combined with sedentary lifestyles, which are fueling the rise of diabetes and hypertension, both precursors to CKD.
Furthermore, the accessibility and affordability of healthcare services remain significant barriers in rural areas, where CKD prevalence is often underdiagnosed or mismanaged. This geographic disparity underscores the importance of addressing healthcare inequities in combating CKD.
CKD not only affects health but also places a heavy financial burden on individuals and families. The costs of dialysis and kidney transplantation are prohibitively high for many, making the disease a significant contributor to out-of-pocket healthcare expenditure in India.
Insurance coverage for CKD-related expenses remains limited, leaving patients to shoulder a large share of the financial burden. For many, this results in delayed or inadequate treatment, worsening disease outcomes.
Comprehensive CKD management: Health monitoring, lifestyle changes, and insurance
Managing CKD risk requires a multi-pronged approach. Routine health check-ups, particularly for individuals with diabetes or hypertension, can facilitate early detection of kidney damage. Blood and urine tests, such as serum creatinine and albumin-to-creatinine ratio (ACR), are vital for monitoring kidney function.
Lifestyle modifications, including maintaining a balanced diet, reducing salt intake, staying hydrated, and exercising regularly, play a pivotal role in preventing the onset of CKD. For those already diagnosed, adherence to treatment protocols, including prescribed medications and dietary guidelines, is essential to slowing disease progression.
Insurance holders should also prioritise financial risk management by ensuring adequate health coverage for CKD and related complications. Policies with critical illness riders or specific kidney care benefits can provide a crucial safety net.
Insurance apps can help users stay on top of renewals, understand policy benefits, and explore options for enhanced coverage, ensuring financial preparedness for potential CKD-related healthcare needs. Try CoverSure – find out is CoverSure a legit insurance app.
Combating CKD in India
The fight against Chronic kidney disease in India requires both individual and systemic efforts. On a personal level, awareness, regular health screenings, and lifestyle changes can significantly reduce the risk.
At a broader level, improved healthcare infrastructure, targeted awareness campaigns, and policies that make treatment accessible and affordable are critical. By taking a proactive approach, individuals and families can mitigate the risks of CKD and protect their health and financial well-being.
