Growing older often brings attention to heart, lung, and joint health, but kidney function remains surprisingly under-recognized. Globally, an estimated 788 million adults lived with chronic kidney disease (CKD) in 2023.
In India, the prevalence has increased from approximately 11.1% during 2011-17 to around 16.4% between 2018 and 2023. Among seniors, the risk soars: reduced kidney filtration and albuminuria significantly raise the likelihood of cardiovascular illness, hospitalization, and loss of independence.
Early stages of CKD usually cause no symptoms; in fact, many affected adults remain unaware of their condition. Against this backdrop, it is not surprising that CKD is emerging as one of the top ten causes of death worldwide.
This article explains what chronic kidney disease is, how it develops and progresses, and what early warning signs to look out for. Most importantly, it outlines how seniors and their families can collaborate to prevent kidney damage and maintain quality of life.
What Is Chronic Kidney Disease
Chronic kidney disease (CKD) refers to a gradual loss of kidney function over time. The kidneys filter waste, balance fluids, regulate blood pressure, and support bone health and red blood cell production. When their function begins to decline, these processes become less efficient, often without obvious symptoms in the early stages.
Doctors define chronic kidney disease as reduced kidney filtration or abnormal levels of protein in the urine that persist for several months. It is a slow-moving condition for many older adults, which makes early understanding and timely screening essential. Even modest changes in kidney function can influence overall health, energy, appetite, and resilience, especially in seniors living with other chronic illnesses.
Why Kidney Health Is Important for Older Adults
Kidney function slows down with age, but chronic kidney disease is not something every older adult is destined to develop. It usually appears when natural age-related changes are combined with long-standing health issues such as diabetes or high blood pressure. These conditions are very common in India and are often detected late or managed irregularly, which places extra strain on the kidneys over many years.
For many seniors, chronic kidney disease grows quietly in the background. It does not cause pain or obvious discomfort initially, which is why it can often go unnoticed for so long. By the time the kidneys lose a significant amount of their filtering ability, symptoms such as swelling, fatigue, breathlessness, or a decrease in appetite begin to appear.
Another reason CKD is becoming more common is related to everyday habits. Modern lifestyles, frequent use of over-the-counter pain medicines for joint pain, and limited routine screening all increase the chances of kidney stress over time.
How Chronic Kidney Disease Begins and Progresses
The kidneys contain millions of tiny filtering units that work continuously throughout life. When these filters are exposed to high blood pressure, high blood sugar, infections, or harmful medications, they begin to wear down. Once damaged, they do not regenerate easily. The loss is gradual at first, then becomes more noticeable as more filters fail.
Chronic kidney disease may start after years of diabetes or uncontrolled blood pressure. It may follow repeated episodes of kidney infections, obstruction from untreated prostate enlargement, long-term use of certain painkillers, or exposure to toxins. In some seniors, autoimmune diseases or inherited kidney conditions play a role. For a few, the cause remains unclear.
The decline usually follows stages. At first, the kidneys work harder to compensate. Later, as filtration decreases, waste products accumulate, causing tiredness, swelling, nausea, and other symptoms. Understanding this slow progression helps families appreciate why regular monitoring is important, even when the older adult appears stable.
Early Symptoms Families Should Pay Attention To
In its early stages, chronic kidney disease rarely announces itself. Many seniors feel well and are able to continue their routines. The earliest changes often resemble ordinary ageing, which makes them easy to dismiss.
As kidney function declines further, the body begins to send clearer signals. These may include:
- Persistent tiredness that does not improve with rest
- Swelling in the legs, ankles, or around the eyes
- Breathlessness during routine activities
- A noticeable decrease in appetite
- Nausea, indigestion, or a change in the taste of food
- Itchy or dry skin
- Muscle cramps, especially at night
- More frequent urination at night
- Foamy urine, which may indicate protein loss
- Difficulty concentrating or feeling mentally slower
None of these symptoms confirms chronic kidney disease on its own, but they do signal that medical evaluation is necessary.
Who Is at Higher Risk
Chronic kidney disease develops more commonly when specific health and lifestyle factors are present. Older adults are at higher risk if they have:
- Long-standing diabetes or high blood pressure
- Heart disease or a history of stroke
- Obesity or a sedentary lifestyle
- A family history of kidney conditions
- Repeated kidney infections
- Enlarged prostate leading to urinary obstruction
- Long-term use of over-the-counter painkillers
- Exposure to contaminated water, unregulated herbal medications, or agricultural chemicals
- Chronic dehydration is often seen in seniors who avoid drinking adequate water
In India, certain risks play an additional role. Many seniors rely on unprescribed pain medicines for joint pain, which can harm the kidneys over time. Others may have lived in regions where water quality poses health risks. Early screening becomes especially important for people with these exposures, even if they feel well.
How Screening and Diagnosis Are Done
Chronic kidney disease often progresses quietly, which is why routine screening matters so much for older adults. Diagnosis does not rely on a single test. Doctors usually look at patterns that emerge over time and combine several investigations to understand how well the kidneys are working.
The primary tools include:
- Blood tests: A simple blood test measures creatinine, which is used to estimate the glomerular filtration rate (eGFR). Persistently low eGFR values suggest reduced kidney function.
- Urine tests: The urine albumin–creatinine ratio (ACR) helps detect early protein leakage into the urine. Even small amounts are meaningful, as they often indicate early kidney damage long before symptoms appear.
- Blood Pressure Monitoring: High blood pressure can damage the kidneys silently. Regular checks help identify seniors who require closer monitoring to protect their kidney function.
- Blood Sugar Evaluation: Older adults with diabetes require routine screening because elevated glucose levels can damage kidney filters over time.
- Ultrasound and Additional Tests: Imaging may be advised if obstruction, long-term infection, or anatomical changes are suspected.
How Chronic Kidney Disease Is Staged
Kidney function is assessed in stages. These stages help families understand how far the condition has progressed and what kind of care may be required. The most widely accepted method classifies CKD into five stages based on eGFR levels.
| Stage | eGFR (ml/min/1.73 m²) | What It Means |
| Stage 1 | 90 or higher | Normal filtration with evidence of kidney stress or protein leakage |
| Stage 2 | 60 to 89 | Mild reduction in function, often without symptoms |
| Stage 3a | 45 to 59 | Moderately reduced filtration; early symptoms may appear |
| Stage 3b | 30 to 44 | Clear reduction with increasing physical signs |
| Stage 4 | 15 to 29 | Severe decline, higher risk of complications |
| Stage 5 | Below 15 | Very low function; symptoms are significant and require specialized care |
How Seniors Can Prevent Kidney Decline
Kidney damage is not always reversible, but it can be slowed significantly. Prevention focuses on protecting the kidneys from stress and correcting the conditions that strain them.
- Manage Blood Pressure: Maintaining blood pressure within the recommended range is one of the most effective ways to protect your health. Regular checks, medication adherence, and a reduced salt intake help maintain kidney function.
- Control Diabetes Carefully: Stable blood sugar protects kidney filters from long-term injury. Routine monitoring, balanced meals, and medication review all play a role.
- Choose Kidney-safe Nutrition: Diets rich in fresh vegetables, fruits, whole grains, adequate protein, and low sodium support kidney health. Seniors benefit from limiting packaged snacks, pickles, salted foods, and fried items.
- Avoid Unnecessary Pain Medications: Long-term use of certain over-the-counter painkillers can harm the kidneys. Safer alternatives should be discussed with a doctor.
- Stay Hydrated: Many older adults reduce water intake to avoid frequent urination. Gentle hydration through small, regular sips helps prevent dehydration, which strains the kidneys.
- Maintain a Healthy Weight: Gentle daily movement, appropriate activity levels, and mindful eating help reduce the burden on the kidneys.
- Check Medications Regularly: Seniors often take multiple medicines. Reviewing these with a doctor or pharmacist helps avoid drug combinations that may strain the kidneys.
- Be Cautious with Herbal Products: Unregulated supplements can contain harmful substances that stress the kidneys. Medical advice is essential before using them.
How Chronic Kidney Disease Is Managed In Older Adults
Management focuses on slowing progression, preventing complications, and supporting daily comfort. Care needs vary depending on how advanced the disease is and what other health conditions the senior has.
- Stabilizing Blood Pressure and Blood Sugar. These remain the foundation of CKD care. Good control reduces further kidney damage and protects the heart.
- Using Appropriate Medications: Doctors may prescribe drugs that reduce protein leakage into the urine or protect the kidneys from stress. Medication timing and dosing matter, especially when other chronic conditions are present.
- Monitoring Complications: Anemia, bone weakness, fluid overload, and electrolyte imbalances can develop as CKD progresses. Regular blood tests help identify and treat these early.
- Adjusting Diet and Protein Intake: Depending on the stage of CKD, some seniors may need guidance on protein balance. Dietitians play an important role in tailoring meals so that nutrition remains adequate without straining the kidneys.
- Reviewing Medicines for Safety: Older adults often use medicines for heart disease, diabetes, arthritis, or sleep problems. Some may need adjustments to avoid unnecessary kidney stress.
- Supporting Emotional Well-being: Chronic illness affects how seniors feel and how they participate in daily activities
When Families Should Seek Urgent Medical Help
Certain changes require prompt attention because they may signal worsening kidney function or complications related to chronic kidney disease. Families should act quickly if an older adult experiences:
- A sudden drop in the amount of urine passed
- New or rapidly worsening swelling in the legs, feet, or around the eyes
- Difficulty breathing, especially at rest
- Persistent vomiting or nausea that limits food or fluid intake
- Severe tiredness, confusion, or unusual drowsiness
- Chest discomfort or a feeling of heaviness
- A high fever along with urinary discomfort
- Blood pressure readings that stay much higher than usual
These signs do not always indicate an emergency, but they do suggest that the kidneys may be under strain. Seeking medical guidance early helps prevent avoidable complications and gives families clarity about next steps.
Chronic Kidney Disease and India’s Health Landscape
Chronic kidney disease is increasingly recognized as a growing health challenge in India. Several factors contribute to this rise. Diabetes and hypertension remain widespread across the country and are often diagnosed late, which increases the risk to the kidneys. In many regions, long-term use of unprescribed pain medicines is common, especially among older adults living with joint pain.
Studies also show geographical variation. Some districts report higher numbers of CKD due to water quality concerns, agricultural exposures, or limited access to preventive healthcare. Access to dialysis and transplant services varies across states, and many families encounter delays in seeking care because symptoms appear slowly.
