What is Chronic Kidney Disease (CKD)?
Chronic Kidney Disease (CKD) is a progressive condition where the kidneys gradually lose their ability to filter waste and excess fluids from the blood. With over 17% of India's population affected by some form of kidney disease, CKD is one of the most significant health challenges facing the country today. Early detection and proper management can slow progression and significantly improve quality of life.
Understanding CKD Stages by GFR
CKD is classified into 5 stages based on the Glomerular Filtration Rate (GFR), which measures how well your kidneys filter blood: Stage 1 (GFR 90+): Kidney damage with normal function. Often no symptoms. Detected through urine tests showing protein or blood. Treatment focuses on managing underlying causes like diabetes or hypertension. Stage 2 (GFR 60-89): Mild reduction in kidney function. Still largely asymptomatic. Regular monitoring and lifestyle modifications are essential. Blood pressure control becomes critical. Stage 3a (GFR 45-59) & 3b (GFR 30-44): Moderate kidney damage. Symptoms may appear — fatigue, fluid retention, changes in urination. This is when most patients are first diagnosed. Nephrology consultation is strongly recommended at this stage. Stage 4 (GFR 15-29): Severe kidney damage. Significant symptoms including nausea, bone disease, anaemia, and appetite loss. Treatment planning for dialysis or transplant should begin. Diet restrictions become important. Stage 5 (GFR below 15): Kidney failure (End-Stage Renal Disease). Dialysis or kidney transplant is necessary for survival. With proper management including home hemodialysis, many patients maintain good quality of life.
Warning Signs You Should Not Ignore
Common early warning signs of kidney disease include: persistent fatigue and weakness, swelling in ankles, feet, or around the eyes, foamy or bubbly urine (indicating protein), blood in urine (pink, red, or cola-coloured), frequent urination especially at night, difficulty concentrating, poor appetite and unexplained weight loss, muscle cramping especially at night, dry and itchy skin, and persistent high blood pressure resistant to medication.
When Should You See a Nephrologist?
You should consult a nephrologist immediately if you have diabetes or hypertension with declining kidney function, a family history of kidney disease, GFR below 60 (CKD Stage 3 or higher), persistent protein or blood in urine, recurrent kidney stones or urinary tract infections, or unexplained decline in kidney function on routine blood tests. Early referral to a nephrologist can delay or prevent the need for dialysis.
CKD Treatment Options in India
Treatment varies by stage and includes: medication management (ACE inhibitors, ARBs, SGLT2 inhibitors), dietary modifications (low sodium, controlled protein, potassium management), blood pressure and diabetes control, anaemia management with EPO injections, phosphate binders for bone health, and in advanced stages — dialysis (in-centre, home hemodialysis, or peritoneal dialysis) or kidney transplant evaluation. Home hemodialysis, pioneered in India by centres like RENACARE, offers patients greater flexibility and often better outcomes than traditional in-centre dialysis.
