Why is kidney failure called the silent killer?

Kidney failure, a silent killer, often goes unnoticed as the body adapts, masking symptoms like fatigue and swelling. The kidneys don’t cry for help. They whisper — and those whispers are easy to miss. That’s what makes kidney failure one of the most silent and dangerous health threats. But with awareness, early checks, and a bit of cautious observation, it’s possible to stay one step ahead of this silent killer.
