Hemodialysis and Peritoneal Dialysis
Hemodialysis (HD) and Peritoneal Dialysis (PD) are advanced renal replacement therapies used to support patients with severe kidney dysfunction or kidney failure. When the kidneys lose their ability to effectively remove waste products, excess fluids, and toxins from the body, dialysis helps perform these essential functions artificially and maintains overall body balance.
At the clinic of Dr. Pranav Tyagi, comprehensive dialysis care is provided with a patient-centred and evidence-based approach. The focus is on improving quality of life, managing complications, ensuring treatment safety, and helping patients lead healthier and more active lives despite kidney disease.
Every dialysis treatment plan is personalised according to the patient’s medical condition, lifestyle, kidney function status, and long-term treatment goals.
What is Dialysis?
Dialysis is a medical treatment that performs the filtration work of damaged kidneys by removing:
- Waste products
- Excess fluids
- Harmful toxins
- Electrolyte imbalance
Dialysis becomes necessary when kidney function declines severely, usually in advanced Chronic Kidney Disease (CKD) or End-Stage Renal Disease (ESRD).
The two major types of dialysis are:
- Hemodialysis (HD)
- Peritoneal Dialysis (PD)
Hemodialysis (HD)
What is Hemodialysis?
Hemodialysis is a procedure in which a dialysis machine and special filter called a dialyzer are used to clean the blood outside the body. Blood is removed through a vascular access, filtered through the dialysis machine, and then returned to the body.
Hemodialysis is commonly performed:
- In dialysis centres or hospitals
- Typically 2–3 times per week
- Under medical supervision
How Hemodialysis Works
Blood Removal
Blood is taken from the body through a vascular access such as a fistula, graft, or catheter.
Filtration Process
The dialysis machine removes waste products, toxins, and excess fluids.
Clean Blood Return
Filtered blood is safely returned to the body.
Monitoring During Treatment
Blood pressure, fluid balance, and overall patient condition are monitored continuously.
Benefits of Hemodialysis
- Effective toxin and fluid removal
- Helps maintain electrolyte balance
- Improves symptoms of kidney failure
- Reduces swelling and breathing difficulty
- Performed under professional supervision
Types of Vascular Access for HD
Arteriovenous (AV) Fistula
A surgically created connection between an artery and vein.
Why It Is Preferred
It provides long-term, safer, and more effective dialysis access.
AV Graft
A synthetic tube connects the artery and vein when veins are not suitable for fistula creation.
Why It Is Important
Provides reliable blood flow for dialysis treatment.
Dialysis Catheter
A temporary tube inserted into a large vein.
Why It Is Important
Used for emergency or short-term dialysis access.
Peritoneal Dialysis (PD)
What is Peritoneal Dialysis?
Peritoneal Dialysis is a home-based dialysis treatment that uses the lining of the abdomen (peritoneal membrane) as a natural filter to remove waste products and excess fluid from the body.
A special dialysis fluid is introduced into the abdominal cavity through a catheter. Waste products and extra fluids pass into the fluid, which is later drained and replaced.
How Peritoneal Dialysis Works
Catheter Placement
A soft catheter is placed into the abdomen through a minor surgical procedure.
Dialysis Fluid Infusion
Special sterile dialysis fluid is introduced into the abdominal cavity.
Waste & Fluid Removal
The peritoneal membrane acts as a filter, removing toxins and extra fluids.
Fluid Drainage & Exchange
Used dialysis fluid is drained and replaced with fresh fluid regularly.
Types of Peritoneal Dialysis
Continuous Ambulatory Peritoneal Dialysis (CAPD)
Manual fluid exchanges are performed several times during the day.
Benefits
- No machine required
- Greater independence and mobility
- Flexible treatment schedule
Automated Peritoneal Dialysis (APD)
A machine performs fluid exchanges automatically, usually during sleep.
Benefits
- Convenient overnight treatment
- More daytime freedom
- Reduced manual exchanges
Benefits of Peritoneal Dialysis
- Home-based treatment convenience
- Greater lifestyle flexibility
- Fewer dietary restrictions in some patients
- Gentle and continuous fluid removal
- Increased independence and mobility
Who Needs Dialysis?
Dialysis may be recommended for patients with:
- End-Stage Kidney Disease (ESRD)
- Severe Chronic Kidney Disease
- Acute Kidney Injury (AKI)
- Severe fluid overload
- Dangerous electrolyte imbalance
- Uncontrolled toxin accumulation
Symptoms Indicating Dialysis Need
Severe Fatigue
Toxin buildup may cause extreme weakness and reduced energy.
Swelling in Legs & Face
Fluid overload can lead to visible swelling.
Difficulty Breathing
Fluid accumulation may affect lung function.
Persistent Nausea & Vomiting
Waste accumulation can affect digestion and appetite.
Reduced Urine Output
Kidney failure often decreases urine production.
Uncontrolled Blood Pressure
Advanced kidney disease may cause severe hypertension.
Dialysis Planning & Patient Counselling
At the clinic of Dr. Pranav Tyagi, detailed dialysis counselling is provided to help patients and families understand:
- Dialysis options
- Lifestyle modifications
- Treatment expectations
- Dietary guidance
- Infection prevention
- Long-term kidney care planning
Every patient receives support in selecting the most suitable dialysis modality according to their medical and lifestyle needs.
Lifestyle & Dietary Management During Dialysis
Fluid Restriction
Fluid intake may be adjusted to prevent overload.
Why It Is Important
Excess fluid can increase strain on the heart and lungs.
Kidney-Friendly Diet
Dietary recommendations may include salt, potassium, and phosphorus management.
Why It Is Important
Proper nutrition helps maintain energy and reduce complications.
Infection Prevention
Dialysis access care and hygiene are extremely important.
Why It Is Important
Infections can lead to serious complications and hospitalisation.
Medication Compliance
Regular medicines help control blood pressure, anemia, and electrolyte balance.
Why It Is Important
Proper medication management improves dialysis outcomes and overall health.
Benefits of Early Dialysis Planning
- Prevents emergency complications
- Allows safer vascular access preparation
- Improves treatment adaptation
- Enhances long-term quality of life
- Reduces hospitalisation risk
- Supports smoother transition to dialysis care

Frequently Asked Questions (FAQs)
1. What is dialysis?
Dialysis is a treatment that removes waste products, toxins, and excess fluid when the kidneys cannot function properly.
2. What is the difference between Hemodialysis and Peritoneal Dialysis?
Hemodialysis uses a machine to filter blood outside the body, while Peritoneal Dialysis uses the abdominal lining as a natural filter.
3. How often is Hemodialysis performed?
Most patients undergo hemodialysis around 2–3 times per week, depending on their condition.
4. Can Peritoneal Dialysis be done at home?
Yes, Peritoneal Dialysis is commonly performed at home after proper training and guidance.
5. Is dialysis painful?
Dialysis itself is generally not painful, although some patients may experience mild discomfort during access procedures.
6. Can dialysis cure kidney disease?
Dialysis does not cure kidney disease but helps replace lost kidney function and manage symptoms.
7. What foods should dialysis patients avoid?
Patients may need to limit salt, potassium, phosphorus, and excessive fluid intake according to medical advice.

9. Can dialysis patients lead normal lives?
With proper treatment, diet, and medical care, many dialysis patients continue active and productive lives.
