Kidney Disease: How Your Urine Can Reveal Hidden Problems

Kidney Disease: How Your Urine Can Reveal Hidden Problems

The Silent Threat

Kidney disease often develops quietly, with few early symptoms. But your urine can hold important clues about your kidney health.

Protein Power

One key sign of kidney trouble is protein in the urine, called proteinuria. Healthy kidneys keep protein in your blood, so its presence in urine can indicate damage to the kidney's filtering system. Persistent proteinuria is a red flag for kidney disease.

Cellular Clues

Microscopic examination of urine can reveal important cells. Red blood cells may indicate inflammation or damage. White blood cells might suggest infection. And kidney cells in urine could point to serious kidney injury.

Crystal Clear

Certain crystals in urine can be normal, but others may indicate problems. Calcium oxalate crystals, for example, are associated with kidney stones. Cystine crystals can reveal a rare genetic disorder. Your doctor can identify these crystals under a microscope.

Foam Factor

Excessively foamy urine that doesn't go away after flushing can be a sign of protein in the urine. While a little foam is normal, persistent foaminess should be checked out as it could indicate kidney issues.
