Nephrology
Doctor Title: Nephrologist
Specializes in kidney health, chronic kidney disease (CKD), dialysis care, and electrolyte disorders.
What Does a Nephrologist Do?
Nephrology is the medical discipline focused on kidney function and renal diseases. Nephrologists preserve kidney architecture, manage fluid retention, treat acid-base disturbances, oversee hemodialysis and peritoneal dialysis, and care for kidney transplant recipients.
Core Clinical Responsibilities:
- Evaluates glomerular filtration rates (eGFR) and slows chronic kidney disease progression.
- Manages resistant hypertension originating from renovascular and renal parenchymal diseases.
- Corrects dangerous electrolyte imbalances including hyperkalemia, hyponatremia, and acidosis.
- Prescribes and manages outpatient hemodialysis and peritoneal dialysis regimens.
- Coordinates kidney transplant waitlisting and post-transplant immunosuppression regimens.
When to See a Nephrologist
You should consider scheduling an evaluation with a Nephrologist if you experience any of the following warning signs or persistent symptoms:
Persistent swelling (edema) in ankles, feet, legs, or around the eyes upon waking
Foamy or frothy urine indicating significant protein leakage (proteinuria)
Unexplained decline in kidney filtration rates (elevated serum creatinine)
Blood in the urine (hematuria) without pain or kidney stones
Severe, refractory high blood pressure requiring four or more antihypertensive medications
Metallic taste in the mouth, nausea, and persistent fatigue caused by uremic toxins
Conditions & Diseases Treated
A Nephrologist provides specialized diagnostic workups and therapeutic management for a wide range of conditions, including:
Common Tests & Procedures Ordered
To confirm diagnoses and monitor treatment effectiveness, a Nephrologist frequently utilizes the following clinical tests and procedures:
Kidney Function Test (KFT / RFT - Creatinine, BUN, eGFR)
Read Lab Test GuideStandard baseline panel quantifying serum creatinine, blood urea nitrogen, and calculated filtration rate.
Urine Microalbumin & Albumin-to-Creatinine Ratio (uACR)
Read Lab Test GuideSensitive early biomarker measuring tiny quantities of albumin leaking through damaged glomeruli.
Serum Electrolytes (Sodium, Potassium, Chloride, Bicarbonate)
Read Lab Test GuideEssential panel monitoring renal excretion and avoiding life-threatening cardiac arrhythmias.
Renal Ultrasound
Non-invasive sound wave scan measuring kidney size, cortical thickness, cysts, and hydronephrosis.
Percutaneous Ultrasound-Guided Renal Biopsy
Microscopic core tissue evaluation necessary to establish definitive glomerulonephritis diagnoses.
Subspecialties & Advanced Fellowships
Within Nephrology, physicians may pursue additional fellowship training to concentrate on specialized surgical procedures or disease subsets:
Frequently Asked Questions
Make the most of your consultation with a Nephrologist by coming prepared:
- Bring all recent blood and urine test reports showing creatinine levels over the past 1 to 2 years to gauge disease progression.
- List all over-the-counter NSAID painkillers (like ibuprofen, naproxen) or herbal remedies taken, as many injure kidneys.
- Record your daily urine output and bring a home blood pressure log.
