Your kidneys filter about 180 litres of blood every day, removing waste and balancing fluids, minerals and blood pressure. They're also remarkably uncomplaining — symptoms of kidney disease typically appear only after 60–70% of function is already lost.
Why Indians Are at Higher Risk
India is seeing a surge in chronic kidney disease, driven by its two biggest causes:
- Diabetes — high sugar damages the kidney's delicate filters year after year
- High blood pressure — strains the same filtering units
- Add frequent painkiller overuse, and the risk multiplies
What the KFT Measures
- Serum Creatinine — the key marker. A muscle waste product your kidneys should clear; rising levels mean falling filtration.
- Blood Urea — another waste product; elevated when kidneys struggle
- Uric Acid — high levels cause gout and can both cause and result from kidney issues
- Electrolytes (Sodium, Potassium, Chloride) — the balance your kidneys maintain; critical for heart rhythm and nerve function
Your doctor can also calculate eGFR from creatinine — a percentage-like score of kidney function.
Early Warning Signs (When They Do Appear)
- Swelling around ankles or eyes, especially mornings
- Foamy urine (protein leakage)
- Changed urination frequency, especially at night
- Unexplained fatigue and loss of appetite
Who Should Test Yearly
- Every diabetic and hypertensive — no exceptions
- Anyone above 40
- Regular painkiller users
- Family history of kidney disease
Caught early, kidney decline can be slowed dramatically with BP control, sugar control and medication adjustments.
