Comprehensive Nephrology Care: Managing Kidney Health Long-Term
Dr. Feliciano Serrano
Nephrologist
Your kidneys are remarkable organs that work 24/7 to filter waste, balance fluids, regulate blood pressure, and produce hormones essential for bone health and red blood cell production. Comprehensive nephrology care focuses on protecting these vital functions and managing kidney disease at every stage.
What Does a Nephrologist Do?
Nephrologists specialize in diagnosing and treating kidney-related conditions. We provide comprehensive care for chronic kidney disease, acute kidney injury, electrolyte disorders, hypertension related to kidney disease, and complications from diabetes affecting the kidneys.

Stages of Chronic Kidney Disease
Stage 1 (GFR ≥90): Normal or High Function
Kidney function normal but with kidney damage (protein in urine). Focus on controlling blood pressure and diabetes.
Stage 2 (GFR 60-89): Mild Loss
Slight decrease in function. Lifestyle modifications and medication to slow progression.
Stage 3 (GFR 30-59): Moderate Loss
More intensive monitoring and treatment. Address complications like anemia and bone disease.
Stage 4 (GFR 15-29): Severe Loss
Prepare for dialysis or transplant. Close monitoring of all kidney functions.
Stage 5 (GFR <15): Kidney Failure
Dialysis or kidney transplant needed to sustain life.
Key Aspects of Kidney Care
Blood Pressure Control
Target BP below 130/80 mmHg. ACE inhibitors or ARBs are preferred as they protect kidneys. Regular monitoring is essential as kidney disease and high blood pressure form a dangerous cycle.
Diabetes Management
Keep HbA1c below 7%. Newer medications like SGLT2 inhibitors not only control blood sugar but also protect kidneys and heart. We work closely with your endocrinologist for optimal diabetes control.
Dietary Modifications
Kidney-friendly diet varies by CKD stage. Generally includes limiting sodium (under 2,300mg daily), monitoring protein intake, managing potassium and phosphorus, and staying hydrated. We provide personalized nutritional guidance.
Medication Safety
Many medications must be dose-adjusted for kidney function. Avoid NSAIDs (ibuprofen, naproxen) which can harm kidneys. Always inform all your doctors about your kidney disease before starting new medications.
Expert Nephrology Care Throughout Southern California
Dr. Serrano provides comprehensive kidney care from early CKD to advanced kidney disease, including dialysis management and transplant preparation.
When to See a Nephrologist
- GFR below 60 or declining kidney function
- Protein or blood in urine
- Difficult-to-control high blood pressure
- Diabetes with kidney involvement
- Recurring kidney stones
- Family history of kidney disease
Early referral to a nephrologist can significantly slow kidney disease progression and help you avoid or delay dialysis. Don't wait until kidney function is severely compromised—proactive management makes all the difference.
