What Is Proteinuria? Proteinuria is a medical condition in which an excessive amount of protein is present in the urine. Normally, the kidneys filter waste products from the blood while keeping essential proteins in the body. When the kidneys’ filtering units become damaged or weakened, protein can leak into the urine, leading to proteinuria.
Understanding Proteinuria is important because it can sometimes be an early sign of kidney problems. This condition may occur due to several factors, including kidney disease, diabetes, high blood pressure, infections, or certain medications. In some cases, temporary proteinuria can also occur due to dehydration, stress, fever, or intense physical activity.
One of the common signs of proteinuria is foamy or bubbly urine, although many people may not notice symptoms in the early stages. Doctors usually diagnose proteinuria through urine tests that measure protein levels. Early detection and proper treatment are important to manage the underlying cause and protect kidney health.
