Understanding Hemodialysis: A Lifeline for Kidney Failure | Dr Manish Sharma

Hemodialysis is a life-saving treatment for individuals suffering from kidney failure, a condition where the kidneys can no longer filter waste, excess fluid, and toxins from the blood effectively. This form of dialysis uses a machine to mimic the kidney’s function, helping maintain a balance of fluids, salts, and minerals in the body when the kidneys are no longer able to do so on their own.

As a leading Consultant Nephrologist in Lucknow, Dr. Manish Sharma specializes in providing comprehensive care for patients requiring hemodialysis, offering guidance on the procedure and long-term management.

What is Hemodialysis?

Hemodialysis involves using a dialysis machine that acts as an artificial kidney. During the procedure, a patient's blood is drawn from the body, filtered through a dialyzer (an artificial kidney filter), and then returned to the body after it has been cleaned. This process helps remove waste products like urea, excess salts, and fluids that would otherwise build up in the body and cause severe health complications.

Who Needs Hemodialysis?

Hemodialysis is typically recommended for individuals with end-stage kidney disease (ESKD), where the kidneys have lost about 85% to 90% of their function. It is most often necessary in cases of chronic kidney disease (CKD) that have progressed to kidney failure. Common causes of kidney failure include:

Diabetes
Hypertension (high blood pressure)
Polycystic kidney disease
Glomerulonephritis
Severe kidney infections

For those with these conditions, hemodialysis helps manage symptoms and maintain a reasonable quality of life.

How Does Hemodialysis Work?

Hemodialysis involves several key steps:

Access to Bloodstream: A vascular access point is created for the procedure. This could be an arteriovenous (AV) fistula (a connection between an artery and vein) or a catheter placed in a large vein.
Blood Filtration: Once connected to the dialysis machine, the patient's blood flows through tubing into the dialyzer, where it is cleaned. The dialyzer has two sections, one for blood and one for dialysis fluid (dialysate), which helps remove waste and excess substances from the blood.
Return of Clean Blood: The filtered blood is then returned to the body, with the entire process taking about 3 to 4 hours per session. Hemodialysis is typically performed 3 times a week, depending on the patient’s condition.

Common Symptoms Managed by Hemodialysis

Hemodialysis helps alleviate several symptoms that arise from kidney failure, including:

Fluid retention and swelling: Excess fluid is removed from the blood, reducing swelling in the legs, ankles, and other parts of the body.
Fatigue and weakness: By clearing waste products, hemodialysis can help restore energy levels and reduce fatigue.
High blood pressure: Dialysis helps balance the body's fluid and electrolyte levels, which can help control blood pressure.
Shortness of breath: Removing extra fluid helps prevent fluid buildup in the lungs, making breathing easier.

Life on Hemodialysis: What to Expect

While hemodialysis is crucial for survival, it does require lifestyle adjustments. Patients must adhere to specific dietary guidelines, limit fluid intake, and attend regular dialysis sessions. Though time-consuming, these measures are necessary to ensure effective treatment and avoid complications such as:

Low blood pressure (hypotension)
Muscle cramps
Infection at the access site
Anemia (due to reduced red blood cell production)

Patients undergoing hemodialysis are encouraged to maintain a healthy lifestyle, follow medical advice, and attend routine check-ups to monitor their condition.
