Most people know that heart disease, cancer, and diabetes are major health threats.
Far fewer people realize that chronic kidney disease is rapidly becoming one of the world’s leading causes of death.
A major new collection of studies published in The Lancet reveals that millions of people are living with kidney disease without a diagnosis, missing valuable opportunities for early treatment.
The international research effort was led by Dr. Jennifer Lees of the University of Glasgow and brought together kidney specialists from around the world. Their message is simple but urgent: more people need to be tested before kidney disease progresses to a dangerous stage.
The kidneys perform several vital functions every day. They filter waste from the blood, remove excess water, help control blood pressure, and support many other processes that keep the body healthy. When kidney function gradually declines over time, a person develops chronic kidney disease.
The condition affects an estimated 844 million adults globally. Experts predict that it could become the fifth leading cause of death worldwide by 2040. Despite these alarming numbers, awareness remains extremely low.
One reason is that chronic kidney disease rarely causes symptoms during its early stages. A person may feel completely healthy even while kidney damage is slowly worsening. By the time symptoms such as swelling, fatigue, nausea, or difficulty concentrating appear, significant kidney damage may already have occurred.
Researchers argue that this hidden nature of the disease contributes to widespread underdiagnosis. In wealthier countries, as many as half of all cases may go undetected. In lower-income countries, the situation is likely even worse.
The researchers believe a simple solution could make a major difference. A basic urine test can detect protein leaking into the urine, which is often an early sign of kidney damage. The test is inexpensive and easy to perform, yet it is not consistently used in many healthcare settings.
The study also highlights important inequalities in diagnosis. Women and people from ethnic minority backgrounds are more likely to remain undiagnosed. This means some populations may miss out on treatments that could slow disease progression and improve long-term health outcomes.
The growing burden of kidney disease is closely linked to other chronic illnesses. People with diabetes, high blood pressure, obesity, and cardiovascular disease face a much higher risk of developing CKD. As these conditions become more common worldwide, kidney disease is expected to affect even more people.
Fortunately, researchers say there has been significant progress in understanding and treating the condition. Advances in laboratory testing, genetic analysis, and medical imaging now allow doctors to identify different forms of kidney disease more accurately than ever before. New medications are also helping patients preserve kidney function and avoid dialysis for longer periods.
Experts stress that timing is critical. Treatments work best when kidney disease is identified early. Routine screening using urine tests, blood tests, and blood pressure measurements can detect problems before permanent damage occurs.
The economic impact is another major concern. Advanced kidney disease often requires expensive treatments such as dialysis or transplantation. These therapies place enormous pressure on healthcare systems and can greatly affect patients’ quality of life. Earlier diagnosis could help reduce both healthcare costs and personal suffering.
The researchers are calling on governments, healthcare providers, and policymakers to invest more resources in kidney disease detection and prevention. They believe routine testing should become a greater priority, particularly for people with known risk factors.
This research provides one of the most comprehensive overviews of chronic kidney disease available today. Its strength lies in bringing together global evidence that highlights both the scale of the problem and the opportunities for improvement.
While the papers do not introduce a single new treatment, they make a powerful case that earlier diagnosis could have a greater impact than many people realize. The findings suggest that simple, affordable tests may be one of the most effective tools available to reduce the growing global burden of kidney disease.
