What does a nephrologist do?

A nephrologist is a specialist in internal medicine who has undergone further training in kidney diseases. Kidneys filter approximately 200 litres of blood per day and regulate blood pressure, fluid balance, and electrolytes. When they malfunction — gradually or acutely — the consequences affect the entire body: heart disease risk increases, bone density drops, anaemia develops, and if untreated, kidney failure can become irreversible.

A nephrologist evaluates kidney function through blood tests (creatinine, eGFR, urea, electrolytes), urine analysis (albumin-to-creatinine ratio, protein), imaging (kidney ultrasound), and in some cases kidney biopsy. Based on these results, the nephrologist diagnoses the underlying cause and designs a treatment plan.

Many kidney diseases progress silently for years. Regular monitoring by a nephrologist slows progression significantly — in some cases preventing kidney failure entirely.

Normal creatinine is approximately 0.6–1.2 mg/dL in adults, though normal ranges vary by age, sex, and muscle mass.
