What Is Proteinuria? Proteinuria is a condition in which an excessive amount of protein is found in the urine. Normally, the kidneys act as filters that remove waste and extra fluids from the blood while keeping important substances like proteins in the body. However, when the kidney’s filtering units become damaged, protein can leak into the urine, leading to proteinuria.

Understanding Proteinuria is important because it can be an early sign of kidney-related problems. This condition may occur due to health issues such as diabetes, high blood pressure, kidney disease, infections, or certain medications. Sometimes, temporary proteinuria can also happen due to dehydration, fever, stress, or heavy physical activity.

A common symptom of proteinuria is foamy or bubbly urine, although some people may not notice any symptoms in the early stages. Doctors usually diagnose proteinuria through urine tests. Early detection helps manage the condition and protect long-term kidney health.
