On the occasion of World Kidney Day 2026, the global theme — “Kidney Health for All – Caring for People, Protecting the Planet” — delivers a timely and powerful message. Kidney health is not only about treating disease; it is about prevention, awareness, equal access to care and environmental responsibility. At a time when kidney diseases are steadily increasing worldwide, this theme reminds us that protecting kidney health is both a personal and collective responsibility.
Kidney diseases are often described as “silent” because they progress quietly, without obvious symptoms in the early stages. Many individuals remain unaware of kidney damage until it has advanced significantly. By the time symptoms become noticeable, the condition may already require intensive treatment. This silent progression is what makes kidney disease particularly dangerous and underscores the need for regular screening and awareness.
Chronic Kidney Disease (CKD) affects nearly one in ten adults worldwide. In India, the burden is rising steadily due to the increasing prevalence of diabetes mellitus, hypertension, obesity and cardiovascular disease. Many patients remain unaware of kidney damage until advanced stages, when dialysis or kidney transplantation[1] becomes necessary.
Diabetes and high blood pressure are the leading causes of kidney failure. Persistent high blood sugar damages the kidney’s filtering units over time, while uncontrolled blood pressure injures blood vessels within the kidneys. Without proper management, this damage progresses silently.
The kidneys are vital organs that perform several essential functions necessary for survival. Each kidney is connected to the urinary bladder by a tube-like structure called the ureter, through which urine travels. The bladder acts as a storage organ, holding urine until it is emptied. Most people have two kidneys that silently filter blood and remove waste products in the form of urine. In addition to this, they regulate blood pressure, produce hormones that maintain normal haemoglobin levels, activate vitamin D for bone strength, and balance fluids, salts and minerals in the body. They carry out all these functions efficiently, often without producing noticeable symptoms until their function is severely compromised.
When kidney function declines, harmful substances accumulate in the body, increasing the risk of heart disease, stroke, anaemia and bone disorders. Healthy kidneys are therefore fundamental to overall wellbeing.
Kidney disease is not limited to adults. Children can also be affected, particularly by congenital anomalies present from birth. These may include a single kidney, blockages in the kidney or urinary tract, differences in kidney size, reversal of urine from the bladder back into the kidney, cystic kidney disease and bladder abnormalities.
In older children, urinary tract infections, kidney stones, leakage of protein or blood in the urine, autoimmune diseases and hypertension are more commonly seen. Kidney injury in children may also occur due to over-the-counter medications, nephrotoxic drugs, contrast agents used in certain tests, and toxins such as snake envenomation or wasp stings.
The manifestations of kidney disease in children can vary. Some may have excessive or reduced urine output. Boys may experience a weak urinary stream. Frothy or bloodstained urine, persistent bedwetting beyond an expected age, passage of stones, poor growth, short stature, bending of leg bones, pale skin, easy fatigability and swelling of the body are other warning signs. In severe cases, if children reach end-stage kidney disease, they may require blood purification in the form of dialysis or even kidney transplantation.
Kidney disease can be detected early through simple tests. A blood test measuring serum creatinine and estimating the glomerular filtration rate (eGFR) helps assess kidney function. A urine test to detect albumin or protein can identify early damage.
People at high risk — including those with diabetes, hypertension, heart disease, obesity or a family history of kidney disease — should undergo regular screening at least once a year. Early detection allows timely treatment and significantly reduces complications.
“An ounce of prevention is worth a pound of cure.” This holds especially true for kidney health. Preventive measures include reducing salt intake, ensuring adequate water consumption, staying physically active, avoiding over-the-counter medications without medical advice and regularly checking blood pressure and blood sugar levels.
World Kidney Day also emphasises maintaining a healthy diet, not smoking, and avoiding frequent use of anti-inflammatory painkillers. Regular kidney function testing further strengthens preventive care. These simple steps can greatly reduce the risk of severe kidney disease.
When kidney function declines severely, patients may require kidney replacement therapy in the form of haemodialysis, peritoneal dialysis or kidney transplantation. Although life-saving, these treatments are costly and resource-intensive, and access remains limited in many settings. This highlights the importance of prevention and early intervention.
The message is clear — everyone deserves access to awareness, screening, essential medications and specialist care. Early detection and equitable healthcare access can dramatically reduce complications and improve quality of life.
The kidneys are often called silent organs because they work quietly and efficiently, without obvious signs of trouble until damage becomes severe. That is precisely why caring for them is so important. Stay hydrated, eat healthily, control blood sugar and blood pressure, and avoid unnecessary painkillers. Our kidneys may be silent, but their contribution to life is powerful. Let us recognise these silent lifelines and take active steps to protect them.

Why is early kidney screening important?
Early kidney screening helps detect kidney problems before symptoms appear. Identifying kidney disease at an early stage allows timely treatment and helps prevent serious complications such as kidney failure.
Who should undergo regular kidney screening?
People with diabetes, high blood pressure, obesity, heart disease, or a family history of kidney disease should undergo kidney screening regularly. Annual screening is recommended for individuals at higher risk.
What tests are used to check kidney health?
Kidney health is usually assessed through simple tests such as a blood test for serum creatinine, estimation of glomerular filtration rate (eGFR), and a urine test to detect protein or albumin.
What are the early warning signs of kidney disease?
Kidney disease often develops silently, but possible signs may include swelling in the legs or face, fatigue, changes in urine, frothy or bloodstained urine, and persistent high blood pressure.
Can kidney disease be prevented?
Many cases of kidney disease can be prevented by controlling blood sugar and blood pressure, maintaining a healthy diet, staying hydrated, exercising regularly, and avoiding unnecessary use of painkillers.
Can children develop kidney disease?
Yes, children can also develop kidney disease. It may occur due to congenital abnormalities, urinary tract infections, kidney stones, autoimmune diseases, or exposure to certain medications or toxins.
