Excess Protein in Kidney (Proteinuria)

Proteinuria refers to the presence of excess protein in the urine. Normally, healthy kidneys filter waste products from the blood while retaining essential substances like proteins. When the kidneys are damaged or stressed, protein may leak into the urine—a sign that the kidneys are not functioning properly.

Proteinuria is not a disease itself but often an indicator of an underlying condition such as chronic kidney disease, diabetes, high blood pressure, or glomerulonephritis. Detecting it early is crucial to prevent progression to serious kidney damage.

Signs & Symptoms

In many cases, proteinuria does not cause obvious symptoms and is found during routine urine tests. However, when present, symptoms may include:

  • Foamy or frothy urine (due to excess protein)

  • Swelling in the hands, feet, abdomen, or face (edema)

  • Frequent urination, especially at night

  • Fatigue and weakness

  • Loss of appetite or nausea

  • Uncontrolled high blood pressure

  • Weight gain due to fluid retention

  •  

Diagnostic Procedures

  • Urine Analysis: First-line test to detect protein levels in urine.

  • 24-Hour Urine Collection: Measures the exact amount of protein excreted.

  • Urine Albumin-to-Creatinine Ratio (UACR): Sensitive test to detect early kidney damage.

  • Blood Tests (Creatinine, eGFR): To assess overall kidney function.

  • Imaging Studies (Ultrasound, CT, MRI): To check kidney structure and detect any abnormalities.

  • Kidney Biopsy: In select cases, to determine the exact cause of protein leakage.
