Proteinuria
Proteinuria (Protein in Urine) Nephrologists in Virginia
Protein in urine, medically known as proteinuria, occurs when your kidneys allow an abnormal amount of protein to pass from your blood into your urine. While a small amount of protein is normal, consistently high levels can be a key indicator of kidney damage. Healthy kidneys work like filters, keeping essential proteins in the bloodstream. When these filters are damaged, protein can “spill” into the urine, which can lead to other complications.
Causes of Proteinuria
The causes of proteinuria can range from temporary, benign conditions to more serious, chronic diseases. Temporary causes include strenuous exercise, fever, or dehydration. Persistent proteinuria, however, often points to an underlying kidney issue or a systemic disease affecting the kidneys. The most common chronic causes include uncontrolled diabetes and high blood pressure, which can damage the kidneys’ filtering units over time.

Frequently Asked Questions About Proteinuria (Protein in Urine)
What does protein in the urine mean?
Protein in the urine, also called proteinuria, occurs when the kidneys are not filtering blood properly and allow protein to leak into the urine. While small amounts of protein can be normal, persistent proteinuria may be a sign of kidney disease, diabetes, high blood pressure, or other underlying health conditions. A nephrologist can help determine the cause and recommend appropriate treatment.
What are the symptoms of proteinuria?
Many people with proteinuria have no noticeable symptoms in the early stages. As kidney function declines, symptoms may include swelling in the hands, feet, ankles, or face, foamy urine, fatigue, difficulty concentrating, and changes in urination patterns. If you experience these symptoms, it is important to seek evaluation from a kidney specialist.
What are the symptoms of a kidney cyst?
Most simple renal cysts cause no symptoms. However, larger cysts may occasionally lead to flank pain, abdominal discomfort, urinary symptoms, or a feeling of pressure in the affected area. If symptoms occur, a nephrologist can determine whether the cyst is responsible and recommend appropriate treatment or monitoring.
Can proteinuria be reversed?
In some cases, proteinuria can be reduced or reversed by treating the underlying cause. Managing conditions such as diabetes, hypertension, dehydration, or infections can help lower protein levels in the urine and protect kidney function. Early diagnosis and treatment are key to preventing long-term kidney damage.
How is proteinuria diagnosed?
Proteinuria is typically diagnosed through urine testing, including a urine dipstick test, urine protein-to-creatinine ratio, or a 24-hour urine collection. Your nephrologist may also recommend blood tests, imaging studies, or additional kidney evaluations to identify the underlying cause.
When should I see a nephrologist for proteinuria?
You should see a nephrologist if protein in your urine persists, if you have a family history of kidney disease, or if you experience symptoms such as swelling, fatigue, high blood pressure, or declining kidney function. The nephrologists at Virginia Nephrology Group provide comprehensive proteinuria evaluation and treatment throughout Northern Virginia, helping patients protect their kidney health and reduce the risk of chronic kidney disease.
