PROTEIN IN THE URINE
Proteinuria
The presence of protein in the urine, which can be a sign of kidney damage from diabetes, high blood pressure, glomerular diseases or other conditions. Careful workup guides targeted treatment.
ABOUT THIS CONDITION
What is Proteinuria
Proteinuria refers to the presence of an abnormal amount of protein in the urine. Normally, the kidney filters keep most protein in the blood, allowing only very small amounts to pass into the urine. When the kidney filters are damaged or stressed, protein leaks into the urine in significant quantities. Causes include diabetes, high blood pressure, glomerular diseases, urinary tract infections, transient causes such as fever or strenuous exercise, and rarely, conditions such as multiple myeloma. Most patients with proteinuria have no symptoms, and the condition is detected on routine urine testing. When proteinuria is heavy (as in nephrotic syndrome), it can cause swelling and other symptoms. Proteinuria is an important marker of kidney damage and a significant risk factor for progressive kidney disease and cardiovascular complications. Diagnosis involves quantifying the amount of protein, urine and blood tests, imaging and sometimes kidney biopsy. Treatment focuses on the underlying cause and reducing protein loss with kidney-protective therapy. Dr. Patnam Pravallika Reddy provides comprehensive proteinuria evaluation and care at Lux Hospitals, Hyderabad.

HOW WE TREAT IT
Treatment Approach
Cause Identification with Kidney-Protective Therapy
The most effective approach is identifying and treating the underlying cause — particularly diabetes, high blood pressure or glomerular diseases — combined with kidney-protective medical therapy that reduces protein loss and slows progression of kidney damage.
- 1
Consultation & Assessment
Dr. Pravallika reviews medical history, examines the patient and arranges quantitative urine tests, blood tests and imaging to determine cause and severity.
- 2
Treatment Planning
A personalised plan is created based on the identified cause and severity, with nephrology referral for persistent or significant proteinuria.
- 3
Medical Management
Treatment of underlying causes, kidney-protective medical therapy, dietary advice and management of cardiovascular risk factors.
- 4
Recovery & Follow-up
Regular follow-up with urine and blood tests to monitor response, detect progression and adjust therapy.
AVAILABLE TREATMENTS
Treatment Options
Identifying the Underlying Cause
A careful evaluation determines whether the cause is diabetes, high blood pressure, glomerular disease or another condition.
Treatment of Underlying Causes
Optimal control of diabetes, blood pressure and any autoimmune or systemic conditions significantly reduces proteinuria and protects the kidneys.
Kidney-Protective Medical Therapy
Specific medical therapy reduces protein loss and slows the progression of kidney damage.
Dietary Modification
Personalised dietary advice including controlled salt and, in some cases, protein intake supports kidney health.
Nephrology Referral for Significant Proteinuria (Referral for nephrology)
Patients with significant, persistent or unexplained proteinuria are referred for specialist nephrology evaluation, including consideration of kidney biopsy.
