Proteinuria

Protein in urine, also called proteinuria or albuminuria, occurs when proteins like albumin leak from the blood into urine due to kidney damage. Healthy kidneys prevent this, but kidney disease or some temporary conditions can cause protein leakage.

Frequently Asked Question's About Proteinuria

What does protein in urine mean?

Protein in the urine, known as proteinuria, means that more protein than usual is passing through the kidneys into the urine. It can sometimes be temporary, but persistent proteinuria may indicate that the kidneys need further evaluation.

What can cause proteinuria?

Proteinuria can be associated with conditions such as diabetes, high blood pressure, kidney disease, infections, dehydration, or strenuous physical activity. The cause can vary from person to person, so further assessment may be needed when protein in urine continues.

How is proteinuria diagnosed?

A doctor may begin with a urine test to check for protein. Depending on the result, additional tests such as a urine protein-to-creatinine ratio, blood tests, blood pressure measurement, or kidney imaging may be advised to assess kidney function and identify the possible cause.

Can proteinuria damage the kidneys?

Persistent proteinuria can be a sign of kidney damage and may be associated with worsening kidney function in some cases. Identifying and treating the underlying condition can help reduce further kidney damage and protect kidney health.

When should I consult a nephrologist for protein in urine?

A nephrology consultation is advisable when protein is repeatedly detected in urine, particularly when it is accompanied by swelling, high blood pressure, changes in urination, or abnormal kidney function tests. Early evaluation can help determine the cause and appropriate management.
