What Is Dialysis?

Dialysis is a life-saving medical treatment for people whose kidneys can no longer filter blood the way they should. Healthy kidneys remove toxins, excess fluids, and waste from the bloodstream. They also balance minerals, control blood pressure, and support the body’s overall chemical stability. When the kidneys fail, harmful wastes build up in the body.

This can lead to life-threatening complications like swelling, electrolyte imbalance, shortness of breath, high blood pressure, and heart problems. Dialysis acts as an artificial replacement for these kidney functions, allowing patients to live longer, healthier, and more stable lives. Dialysis does not cure kidney disease, but it replaces enough kidney function to keep the patient safe, active, and medically stable.

Why Dialysis Is Necessary

When kidneys lose most of their function due to chronic kidney disease (CKD), diabetes, hypertension, infections, or other conditions, the body cannot remove toxins and fluids naturally.

Without dialysis, toxins like urea, creatinine, and acids accumulate in the blood. Extra fluid collects in the lungs, heart, and limbs, causing dangerous swelling.

Untreated kidney failure can lead to:


• Severe fatigue
• Vomiting and nausea
• Confusion and sleep disturbances
• Heart failure
• Breathing difficulty
• Swelling of the brain
• Irregular heartbeat
• Coma


Dialysis prevents these risks by cleaning and balancing the blood at regular intervals.

Dialysis maintains:


• Safe potassium levels
• Calcium and sodium balance
• Fluid stability
• Toxin removal
• Safe blood pH levels

This ensures that the patient’s heart, brain, and muscles continue functioning normally

Patients who follow their dialysis schedule live significantly longer than those who miss or skip sessions. Studies consistently show that missing dialysis increases mortality risk by many times.

Types Of Dialysis

Hemodialysis

In hemodialysis, blood is filtered using a medical machine and a dialyzer (artificial kidney). This is the most common form of dialysis and requires regular sessions.

Peritoneal Dialysis

This uses the lining of the abdomen to filter blood. It is less common but suitable for some patients depending on medical conditions.

Diagnex specialises in Home Hemodialysis, offering the convenience and safety of treatment at home under expert supervision.

Why Many Patients Prefer Home Dialysis

Home dialysis has become one of the most preferred choices for kidney patients because it reduces stress, improves comfort, and provides greater freedom.

1. Comfort And Peace Of Mind

Patients feel relaxed in their own home, surrounded by familiar faces and spaces. This reduces anxiety and makes each session emotionally easier.

2. Lower Infection Risk

Hospitals are crowded environments where infections spread easily. Home dialysis significantly lowers this risk, especially for elderly or immunocompromised patients.

3. No Travel Stress

Many patients travel 3 to 4 times a week to dialysis centres. Long travel, traffic, and waiting hours add physical strain. Home dialysis removes all of that.

4. Personalised Care

At home, a Diagnex nurse focuses only on one patient. There is no rush, no multitasking, and no distractions, leading to safer and smoother sessions.

5. Better Flexibility & Scheduling

Patients can choose a convenient time slot between 9 AM and 9 PM. This makes it easier to manage work, family, and daily routines.

6. Emotional Support From Family

Family presence helps patients stay positive and reduces emotional stress.

Frequently Asked Questions about Dialysis

Understanding dialysis can feel overwhelming, especially when you’re already dealing with the challenges of kidney disease or managing care for a loved one. To make things easier, we’ve collected the most important questions patients usually ask when they begin dialysis or consider switching to home-based treatment. These FAQs cover everything from how dialysis works, why it’s needed, types of dialysis, session timings, safety, long-term expectations, home dialysis advantages, and more.

Dialysis is a life-sustaining medical treatment used when the kidneys can no longer filter blood on their own due to chronic kidney disease, end-stage renal disease, or severe kidney failure. During dialysis, waste products, toxins, and extra fluid are removed from the bloodstream using either a hemodialysis machine or the natural lining of the abdomen in peritoneal dialysis. This process helps maintain proper electrolyte balance, blood pressure stability, and overall body function. Dialysis acts as an artificial kidney and is essential for patients whose kidney function has dropped dangerously low and need consistent, medically supervised renal replacement therapy.

Patients need dialysis when their kidneys are unable to remove waste, filter blood, or regulate fluid levels effectively. This usually happens due to advanced chronic kidney disease, diabetes-related kidney damage, hypertension-related kidney failure, or sudden acute kidney injury. Without dialysis, toxins like urea and creatinine build up in the bloodstream, leading to life-threatening complications such as swelling, breathlessness, severe weakness, high potassium levels, fluid overload, and heart failure. Dialysis prevents these complications and keeps the body stable while the patient either awaits kidney function recovery or qualifies for a kidney transplant.

The two main types of dialysis are Hemodialysis and Peritoneal Dialysis. Hemodialysis uses a dialysis machine and dialyzer filter to clean the blood externally; it is commonly performed in hospitals, dialysis centers, and increasingly through home hemodialysis setups. Peritoneal dialysis uses the body’s peritoneal membrane to filter blood internally using specialized dialysis fluid, allowing treatment to be done at home, during the day, or overnight using an automated cycler. Both types are effective kidney replacement therapies, and the choice depends on medical condition, lifestyle, convenience, mobility, infection risk, and long-term kidney care requirements as advised by a nephrologist.

A typical hemodialysis session takes about 3 to 4 hours and is usually performed 2 to 3 times per week depending on the patient’s creatinine levels, fluid retention, and nephrologist recommendations. Peritoneal dialysis timings vary from 30-minute manual exchanges performed multiple times a day to 8–10 hour automated cycles performed overnight while the patient sleeps. Home dialysis (both hemodialysis and peritoneal dialysis) often offers more flexible schedules, better comfort, and improved treatment consistency, especially for working professionals, elderly patients, and those with mobility challenges.

Dialysis itself is not painful because the actual filtering process happens externally or within the abdomen without causing discomfort. Some patients may feel mild, temporary pain during needle insertion in hemodialysis or occasional abdominal fullness during peritoneal dialysis fluid exchanges. Most of these sensations reduce once the patient gets accustomed to the treatment. With trained dialysis nurses, advanced cannulation techniques, high-quality dialysis machines, and proper patient preparation, dialysis becomes a smooth and comfortable experience for long-term kidney failure management.

Most hemodialysis patients require treatment 2 to 3 times a week to maintain safe toxin levels and fluid balance. Some may require more frequent sessions depending on kidney function, age, co-existing conditions, or dialysis efficiency. Peritoneal dialysis patients usually undergo daily treatment, either through Continuous Ambulatory Peritoneal Dialysis (CAPD) or Automated Peritoneal Dialysis (APD). Regular dialysis helps maintain consistent kidney support, stable electrolytes, controlled blood pressure, and an overall better quality of life for chronic kidney disease patients.

Yes, home dialysis is safe, medically approved, and increasingly recommended for patients who want convenience, privacy, and better treatment consistency. With a properly installed home dialysis machine, sterile consumables, NABL-approved medical equipment, and trained dialysis technicians or certified nurses, home hemodialysis and peritoneal dialysis offer the same clinical safety standards as in-center dialysis. Home dialysis reduces travel stress, lowers infection exposure, allows flexible timing, and often delivers better clinical outcomes because treatments are more frequent and comfortable.

Dialysis does not cure kidney disease. It supports the body by taking over the essential filtration work that kidneys can no longer do. Patients may remain on dialysis long-term unless they recover kidney function or receive a successful kidney transplant. Dialysis helps improve symptoms, maintain energy levels, stabilize health, and prevent complications related to kidney failure, making it a vital part of long-term kidney care.

Yes, dialysis patients can travel with proper planning. Many dialysis centers across India and globally offer temporary dialysis appointments, and peritoneal dialysis patients can carry travel-friendly dialysis supplies for exchanges during trips. With the growth of home dialysis and portable dialysis setups, patients now enjoy more independence and mobility without compromising their treatment schedule.

Missing a dialysis session can be dangerous because toxins and fluid build up rapidly in the body. According to medical studies, missing sessions significantly increases the risk of hospitalization, heart complications, breathing difficulties, and even mortality. Consistent dialysis is crucial to maintaining stable health, preventing severe symptoms, and ensuring long-term kidney treatment success. Patients should never skip or delay their scheduled dialysis unless instructed by their nephrologist.
