Chronic Kidney Disease Is Growing Faster Than Most People Realize
Your kidneys may be working hard right now without you even noticing — but a major new global study shows they’re under increasing pressure worldwide.
According to a new analysis published in The Lancet, chronic kidney disease (CKD) now affects an estimated 788 million adults globally. That’s more than double the number from 1990. The condition has become a leading cause of death and disability, driven by aging populations, rising diabetes, high blood pressure, and obesity.
What concerns me most is how silent this disease is. In its early stages, CKD rarely causes noticeable symptoms. Many people only discover they have it when kidney function has already declined significantly. By then, waste begins building up in the blood, and the risk of serious complications rises sharply.
A Double Threat to Heart and Kidneys
One of the most worrying findings is how closely CKD is linked to heart disease. Impaired kidney function significantly raises the risk of cardiovascular events. In many cases, people with kidney disease are more likely to die from heart-related problems than from kidney failure itself.
The study also highlights major inequalities. While wealthy countries have better access to dialysis and transplants, millions in lower-income regions have very limited treatment options, turning CKD into a major driver of suffering and early death.
Why Early Detection Matters
Because routine kidney function testing is not widespread in many health systems, a huge number of cases go undiagnosed until later stages. The researchers emphasize that broader screening — especially for people with diabetes, hypertension, or obesity — could help catch the disease earlier when it’s much more manageable.

What You Can Do
While we can’t control global trends, we can take steps to protect our own kidney health:
- Keep blood sugar and blood pressure well managed
- Maintain a healthy weight
- Stay hydrated and eat a balanced diet
- Avoid long-term overuse of certain pain medications (like NSAIDs)
The scale of this problem is sobering, but the message from the research is clear: chronic kidney disease is no longer a rare condition. Greater awareness and earlier action could prevent a great deal of suffering in the coming years.
