People with proteinuria have unusually high amounts of protein in their urine. The condition is often a sign of kidney disease. Your kidneys are filters that don’t usually let a lot of protein pass through. When kidney disease damages them, proteins such as albumin may leak from your blood into your pee. You can also have proteinuria when your body makes too much protein. Kidney disease often has no early symptoms. Protein in your pee might be one of the first signs. Your doctor may spot proteinuria on a urine test during a routine physical.might have symptoms including:

Foamy or bubbly pee Swelling (edema) in your hands, feet, belly, and face Peeing more often Shortness of breath Fatigue Loss of appetite Upset stomach and vomiting Muscle cramps at night
