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.

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
