What Is Dialysis?
Dr. Anindya Biswas is a Senior Consultant Nephrologist and dialysis specialist in Delhi with 16+ years of experience, providing consultation for patients who need or are already on dialysis. Dialysis is required when the kidneys can no longer maintain adequate fluid, electrolyte and waste balance — but the right timing and type of dialysis depend on the patient’s overall clinical condition, not a single creatinine value.
Dialysis is a treatment that filters waste products and excess fluid from the blood when the kidneys can no longer do so adequately. The two main types are haemodialysis and peritoneal dialysis. Dr. Biswas evaluates each patient to recommend the most appropriate dialysis approach and long-term plan. Call +91 8800224333 to confirm consultation availability.

Dialysis Services Dr. Biswas Provides Consultation For
Dialysis care is individualised according to kidney function, symptoms, other medical conditions, treatment goals and access needs.
- Haemodialysis
- Peritoneal dialysis and CAPD
- Haemodiafiltration (HDF)
- AV fistula evaluation
- Temporary dialysis catheter planning
- Permacatheter care
- CAPD catheter placement planning
- Dialysis complication management
- Long-term dialysis monitoring
These signs do not always mean a serious kidney condition, but they should not be ignored when they persist, worsen, or appear with diabetes, hypertension, infection, heart disease or a known kidney history. A nephrologist helps connect symptoms, reports and risk factors so patients can understand whether the issue is temporary, progressive, procedure-related or part of chronic kidney disease.
When Is Dialysis Needed?
Dialysis may be considered in advanced kidney failure when the kidneys cannot safely control waste, fluid, potassium or acid balance. The decision is individualised and considers symptoms, examination, laboratory trends and the patient’s overall condition.
- Persistent nausea, poor appetite or severe weakness linked to waste buildup
- Fluid overload causing swelling or breathlessness
- Dangerously high potassium
- Acid buildup that cannot be controlled medically
- Very low kidney function with related complications
- Confusion, reduced alertness or other uraemic symptoms
Patients with diabetes, uncontrolled blood pressure, recurrent urinary problems, swelling, high creatinine or proteinuria may need more structured follow-up because early correction can slow complications and reduce emergency admissions.

Dialysis Access — Fistula & Catheter Planning
Haemodialysis requires reliable access to the bloodstream. An AV fistula is commonly preferred for suitable patients who are expected to need long-term haemodialysis, but it needs time to mature. A temporary catheter may be used when dialysis is urgent, while a permacatheter may be considered in selected situations. Access choice and timing are planned after clinical assessment.
The care approach focuses on protecting remaining kidney function, controlling complications, improving symptoms and guiding patients through decisions in simple language. Whenever a procedure such as kidney biopsy, dialysis catheter placement, permacatheter placement, AV fistula planning, CAPD catheter placement, hemodialysis, peritoneal dialysis, hemodiafiltration or plasmapheresis is relevant, the decision should be made after clinical assessment and counselling.
Haemodialysis vs Peritoneal Dialysis
| Feature | Haemodialysis | Peritoneal dialysis |
|---|---|---|
| How it works | Blood is filtered through a dialysis machine. | Dialysis fluid uses the abdominal lining as a natural filter. |
| Where it is done | Usually at a dialysis centre; home options vary. | Usually performed at home after training. |
| Typical schedule | Often several sessions each week, individualised by prescription. | Daily exchanges or overnight automated treatment, as prescribed. |
| Access | AV fistula, graft or dialysis catheter. | A catheter placed into the abdomen. |
| Who it may suit | Patients who prefer or need centre-based blood filtration. | Selected patients able to manage home treatment and infection precautions. |

Patients should bring recent blood reports, urine reports, ultrasound or CT scan reports, discharge summaries, dialysis records, transplant records and current medication lists. For long-term kidney conditions, a timeline of creatinine values, urine protein reports and blood pressure readings is especially helpful.
For urgent symptoms such as severe breathlessness, very low urine output, confusion, chest discomfort, severe weakness or sudden swelling, patients should seek emergency care through the nearest hospital facility rather than waiting for a routine appointment.
