15 Deadly Kidney Disease Symptoms You Need to Detect Early

One of the kidneys' main functions is fluid balance. When the kidneys stop functioning properly, excess fluid has nowhere to drain and accumulates in the tissues.

This causes swelling, also known as edema, which is most noticeable in the ankles, feet, and hands. Over time, the swelling can become more severe and uncomfortable, signaling the need to consult a doctor.

Blood in the urine

Healthy kidneys maintain blood cells in the body while filtering waste products. Blood leaking into the urine can be a warning sign of serious problems, such as infection, kidney stones, or even cancer.

If you notice pink, red, or cola-colored urine, never ignore it. This symptom always requires medical attention.

Foamy or bubbling urine

Occasional bubbles in the urine may be harmless, but persistently foamy urine is cause for concern. This usually indicates protein leakage into the urine—a classic sign of kidney damage.

Protein needs to remain in the blood to support muscles, repair tissue, and maintain normal body functions. Protein loss in the urine indicates kidney problems.

Frequent or decreased urination
