Dialysis Explained: Types, Procedure & how it works?

One of the important functions of the kidneys is to help keep the body healthy by removing waste products and balancing fluid and minerals in the blood. Poor kidney function can lead to the accumulation of unwanted waste products and extra fluid in the body. Under these circumstances, dialysis might be advised to maintain these functions.

Hearing the word “dialysis” can feel overwhelming at first, but understanding how it works can help patients and families feel more informed and reassured. Today’s dialysis therapy is intended to keep the person healthy, control symptoms, and allow him or her to lead many of the same lives that people with diabetes enjoy.

We will address in this guide why dialysis is required, how it functions, the various types of dialysis, and what to anticipate throughout dialysis treatment.

Why and When Is Dialysis Needed?  

Dialysis is a therapeutic procedure that takes over one or more of the functions of healthy kidneys. It may be suggested that when the kidneys can’t expel sufficient waste products, surplus fluids, and toxins from the blood.

India is witnessing a rising number of Chronic Kidney Disease (CKD) cases, with approximately 2.2 lakh new patients reaching End-Stage Renal Disease (ESRD) annually, as per PubMed Central. This places a significant burden on the healthcare system and underscores the importance of preventive kidney care. Dialysis might be required in certain common circumstances:

• Severe chronic kidney disease
• Kidney failure
• Some acute renal failures
• Severe fluid imbalance
• A large accumulation of waste substances in the bloodstream.

Before deciding on dialysis, doctors take the time to examine kidney function through blood and urine tests, symptoms, and imaging studies.

What Symptoms May Indicate the Need for Dialysis?

India has approximately 950 nephrologists serving patients across the country. There are also around 700 dialysis centres equipped with nearly 4,000 dialysis machines, according to Scientific Scholar. A large share of kidney care facilities is situated in private hospitals and metropolitan areas, making advanced nephrology services more accessible to people living in cities.

The symptoms may differ from one person to another and will depend on the degree of kidney function. Common symptoms include:

• Fatigue: If kidney function is impaired, there may be a general sense of fatigue or tiredness.
• Feet, ankles, or hands may become swollen: When the kidneys are not working well, they can accumulate extra fluid in the body.
• Low urine output: If the urine output decreases, the kidneys have decreased function.
• Dyspnea: Sometimes, fluid accumulation in the body can make breathing more difficult.
• Lack of concentration: As the bloodstream becomes more toxic, it can make it harder to focus and think clearly.
• Loss of appetite or nausea: Some may have digestive upset or decreased appetite.
• Difficulty sleeping: Sometimes, changes in the kidneys can disrupt sleep and make it more difficult to get a good night’s rest.
• Retention of fluid: Excess fluid may be retained in the body, causing weight changes and puffiness.

Many health issues can cause these symptoms, and it is important to get a proper medical evaluation. Consulting experienced specialists at a trusted nephrology centre within the best multispeciality hospital in Chennai can help ensure accurate diagnosis, timely treatment, and comprehensive care for underlying kidney-related conditions.

How Does Dialysis Work?

The kidneys do not function properly, and dialysis serves as a substitute for the filtering function. The treatment helps:

• Remove waste products from the blood
• Remove excess fluid
• Maintain electrolyte balance
• Support general health and well-being.

While dialysis is not a perfect substitute for the functions of a healthy kidney, it does take over many of the important filtration roles that a healthy kidney would play. Dialysis helps reduce discomfort and keep you more comfortable while keeping your body in balance.

What Are the Different Types of Dialysis?

There are two main types of dialysis. The best choice is one that suits a person’s medical condition, lifestyle and overall health needs.

Hemodialysis

Hemodialysis is a special machine and filter that removes blood from the body. Treatment involves draining the blood from the body, filtering it through a dialysis machine, and reintroducing it into the body.

Hemodialysis is often done in a dialysis clinic or hospital by trained health care professionals. Depending on medical circumstances, some patients may also be candidates for home-based hemodialysis.

Peritoneal Dialysis

In peritoneal dialysis, the lining of the abdomen (peritoneum) acts as a natural filter. During the procedure, a specially prepared dialysis solution is introduced into the abdominal cavity through a soft catheter. Waste and excess fluids enter the fluid and are drained and replaced.

This can be done at home and can provide more flexibility for certain patients. Peritoneal dialysis is recommended or not depending on the condition and lifestyle of the patient, which is determined by doctors. Access to timely medical support and emergency care is also important for dialysis patients, ensuring immediate attention whenever critical health concerns arise.

Comparison of Hemodialysis and Peritoneal Dialysis

What Happens During a Dialysis Procedure?

Depending on the type of dialysis being performed, the dialysis process will differ.

During Hemodialysis:

• Blood is connected to the dialysis machine through a vascular access.
• The machine removes excess fluid and waste products.
• Cleaned blood is returned to the body.
• The patient is closely monitored by healthcare professionals during the session.

During Peritoneal Dialysis:

• Dialysis fluid is placed into the abdomen.
• The peritoneal membrane allows waste products to enter the fluid.
• The used fluid is replaced with a fresh solution.

Patients are closely monitored to ensure comfort and safety during treatment. They may also require prescribed medications as part of their ongoing care plan, making access to a reliable online pharmacy in Chennai convenient for timely medication refills and uninterrupted treatment support.

Benefits of Dialysis

Dialysis serves to maintain the body when kidney function is greatly diminished. Some benefits include:

• Removal of Waste Products: Dialysis removes waste substances from the bloodstream, which may build up if the kidneys are not working properly.
• Fluid Balance: This treatment removes unwanted fluid and helps to reduce swelling.
• Improved Comfort: A lot of people find that their symptoms improve with the improvement of their kidney function.
• Better Daily Function: Dialysis helps maintain balance within the body and can help restore energy and general good health.
• Support for Long-Term Kidney Care: Dialysis is a procedure that helps the patient live with kidney disease while they continue to work closely with their healthcare team to develop a treatment plan.

Are There Any Side Effects of Dialysis? 

As with other medical treatments, side effects can sometimes occur with dialysis. But medical staff keep a close track of patients and offer support to manage them. Side effects may include:

• Anxiety of fatigue following treatment
• Muscle cramps
• Blood pressure changes
• Headaches
• Mild nausea
• Some people may experience itching.

These effects are not universal, and many symptoms can be controlled with proper medical care. Through periodic follow-up appointments, doctors in Chetpet can fine-tune treatment and make patients more comfortable.

Living Well While Receiving Dialysis

A large number of people still live an active and full life during dialysis. Some healthy habits that can help include:

• Following dietary recommendations
• Maintaining activity as recommended
• Taking medications regularly
• Going to regular dialysis appointments
• Watching intake of fluid when indicated
• Regular medical follow-up is important.

The role of health care workers, family members and caregivers is also significant in overall well-being.

When Should You Consult a Kidney Specialist? 

If swelling in the legs and face, decreased urine output, fatigue, shortness of breath, or changes in urination persist, it is important to see a nephrologist. People who have chronic kidney disease (CKD), diabetes, hypertension or abnormal blood tests for kidney function should also get specialist advice, as these conditions can slowly affect kidney function and may need more monitoring. Certain features like elevated creatinine, proteinuria or falling estimated glomerular filtration rate (eGFR) are significant findings that require nephrology consultation.

A kidney specialist can perform an early assessment to help determine the cause of kidney problems, assess the need for advanced treatments like dialysis, and help develop a strategy to slow the disease process. In Dr Mehta’s Hospitals, the nephrology team offers a holistic treatment for chronic kidney disease, kidney failure, dialysis management, and metabolic complications associated with kidney disorders, ensuring the patients have healthy kidneys and a good quality of life.

Conclusion

Dialysis is a significant treatment used to maintain the body if the Kidneys don’t work well. Dialysis is important because it helps eliminate waste products, excess fluids and toxins from the body, contributing to overall health and quality of life.

Knowing the various kinds of dialysis, how the dialysis procedure works, and what to expect during dialysis can help patients and families feel more confident and informed.
