What is proteinuria?

Proteinuria is the medical name for having protein in your urine.

Healthy kidneys filter waste and extra fluid from blood. The body gets rid of these wastes and fluid through urine. With proteinuria, some protein “leaks” out of the blood along with the wastes.

Protein acts like a sponge in the blood. It holds fluids that the body needs inside arteries and veins. If there is not enough protein, this fluid leaks out into other body tissues. This causes swelling, or edema. This usually happens around the eyes, face, feet, ankles and belly.

Proteinuria is an early sign of kidney damage.
