The first time someone hears the word “dialysis,” it can feel overwhelming. Maybe your doctor has explained that your kidneys are no longer removing enough waste, or a family member has suddenly been advised to start dialysis after a serious kidney problem.
The questions usually come quickly: How often is it needed? Will it hurt? Can normal life continue? And does starting dialysis mean there is no other option?
The answers depend on the person's kidney function, overall health, and medical condition. Dialysis is not something to fear blindly, but it is also not a treatment that should be approached casually.
Healthy kidneys filter waste and extra fluid from the blood. When kidney function becomes severely reduced, dialysis can perform part of this work.
The two main forms are haemodialysis and peritoneal dialysis. Haemodialysis uses a machine and a special filter to clean the blood, while peritoneal dialysis uses the lining of the abdomen as part of the filtering process.
The appropriate option depends on individual medical circumstances and should be decided with a kidney specialist.
Dialysis is already an important part of kidney care in India.
According to the Ministry of Health and Family Welfare's 2024–25 Annual Report, the Pradhan Mantri National Dialysis Programme had reached 1,542 centres across 36 States/UTs by October 2024, with 25.66 lakh patients having availed dialysis services and more than 305 lakh haemodialysis sessions recorded under the programme.
These figures show how significant ongoing renal replacement care has become, particularly for people with advanced kidney disease.
Dialysis itself is generally considered when kidney function has fallen severely or when complications cannot be controlled adequately through other treatment.
Possible warning signs of advanced kidney problems include:
Significant swelling in the feet or face
Major changes in urine output
Persistent nausea or vomiting
Severe tiredness or weakness
Breathlessness caused by fluid buildup
Confusion or difficulty concentrating
Persistent itching
Loss of appetite
Abnormal kidney-function test results
These symptoms can have many causes, so they do not automatically mean dialysis is required.
A nephrologist may review creatinine, eGFR, electrolytes, urine tests, blood pressure, fluid status, symptoms, and other medical reports.
The decision about dialysis is based on the overall clinical picture rather than simply one number from a blood test.
Here is a point many families misunderstand.
Some patients need dialysis temporarily because of acute kidney injury. If the kidneys recover sufficiently after the underlying problem is treated, dialysis may no longer be required.
People with advanced chronic kidney disease may need long-term dialysis unless another treatment, such as kidney transplantation, becomes appropriate.
So, starting dialysis should not automatically be interpreted as a prediction of someone's entire future.
A common assumption is that dialysis should be delayed for as long as possible because starting it means the kidneys have completely “failed.”
That is too simplistic.
The timing of dialysis should be based on symptoms, complications, kidney function, fluid balance, and the patient's overall condition. Delaying medically necessary dialysis can itself create serious problems.
The decision belongs with the treating nephrologist, who can explain the reason for recommending it and discuss the available options.
For example, consider a person with long-standing diabetes and high blood pressure whose kidney function has gradually declined.
Initially, treatment may focus on controlling blood pressure and blood sugar, managing medicines, monitoring kidney function, and addressing diet and fluid needs. If kidney function later becomes severely impaired and complications cannot be controlled adequately, the care plan may need to include dialysis.
This is why regular follow-up matters. Kidney care is often a process rather than a single appointment.
For haemodialysis, blood is circulated through a dialysis machine and filter before being returned to the body.
A typical session requires monitoring of blood pressure, fluid removal, access site, symptoms, and treatment response. The exact schedule varies according to the patient's medical needs.
Good dialysis care also involves more than the machine itself. Nutrition, medication management, vascular access care, infection prevention, and regular nephrology follow-up are important parts of the overall plan.
A kidney clinic may provide or coordinate care for:
Haemodialysis
Peritoneal dialysis
Chronic kidney disease
Acute kidney injury
Diabetic kidney disease
Hypertension-related kidney problems
Electrolyte disorders
Vascular access assessment
Kidney transplant evaluation
Critical care nephrology
Interventional nephrology
At स्वस्थ Kidney Clinic, we believe dialysis care should be explained clearly to patients and families. Our focus is on understanding the underlying kidney condition, reviewing reports carefully, monitoring treatment needs, and helping patients understand what each stage of their kidney-care plan means.
People already receiving dialysis should also pay attention to changes between sessions.
Increasing swelling, breathlessness, fever, unusual weakness, chest discomfort, confusion, or problems around the dialysis access site should be discussed promptly with the treating medical team.
Dialysis schedules and fluid restrictions should also not be changed independently.
The frequency depends on the type of dialysis and the patient's medical condition. Haemodialysis is often scheduled several times a week, but the treating nephrologist determines the appropriate plan.
The dialysis process itself is not usually described as painful, although inserting needles for haemodialysis can cause temporary discomfort. Some patients may experience fatigue, cramps, blood-pressure changes, or other side effects.
Sometimes. Patients with acute kidney injury may recover enough kidney function to stop dialysis. In advanced chronic kidney disease, long-term dialysis may be necessary unless kidney transplantation or another appropriate treatment becomes possible.
If you or a family member has been advised to consider dialysis, do not rely only on information from friends, social media, or old reports.
Speak with a Kidney Care Specialist who can review the current kidney function, symptoms, treatment history, and overall condition before discussing the appropriate next step.
