Key Takeaways
Hemodialysis removes waste and excess fluid when the kidneys can no longer function effectively.
Treatment is typically performed three times per week in a medically supervised dialysis center, with each session lasting about 3–4 hours.
Healthcare professionals closely monitor dialysis, and Medicare covers treatment for eligible patients with End-Stage Kidney Disease (ESKD).
If you or a loved one needs dialysis, choosing the right hemodialysis center is one of the most important decisions for long-term health and stability. Reliable treatment, experienced specialists, and consistent scheduling all play a critical role in protecting your health.
Our dialysis services are overseen by board-certified nephrologists and delivered by experienced dialysis nurses focused on safety, comfort, and coordinated kidney care.
What Is Hemodialysis?
Hemodialysis is a life-sustaining treatment for advanced kidney disease and End-Stage Kidney Disease (ESKD). When the kidneys lose the ability to filter the blood effectively, dialysis replaces essential kidney function.
A dialysis machine and specialized filter (called a dialyzer) remove:
- Waste products
- Extra fluid
- Electrolyte imbalances such as potassium and sodium
During treatment, blood is gently circulated through the dialysis machine, filtered, and safely returned to the body. While hemodialysis does not cure kidney disease, it prevents dangerous toxin buildups and supports long-term stability.
How Does Hemodialysis Work?
Understanding how hemodialysis works can make the process feel more manageable.
- A vascular access (fistula, graft, or catheter) provides safe access to the bloodstream.
- Blood flows into the dialyzer, which acts as an artificial kidney.
- Waste and excess fluid are removed.
- Clean blood returns to your body.
Each session is monitored by trained dialysis nurses under nephrology supervision. Vital signs, fluid balance, and laboratory values are reviewed regularly to ensure safe and effective treatment.
In-Center Hemodialysis: What to Expect
Most patients receive in-center hemodialysis:
- Three times per week
- 3–4 hours per session
- On a consistent schedule (such as Monday/Wednesday/Friday or Tuesday/Thursday/Saturday)
During treatment, patients may rest, read, watch shows, or use personal devices. Our dialysis centers focus on comfort, predictable scheduling, and continuous clinical oversight.
If you are new to dialysis, our team provides education and guidance to help you feel confident about your care plan.
How Long Does Dialysis Take?
A common question is: how long does dialysis take?
- Each treatment: 3–4 hours
- Frequency: Typically, three times weekly
- Duration of therapy: Ongoing unless a kidney transplant is performed
Your nephrologist adjusts treatment time and fluid removal based on lab results, symptoms, and overall health needs.
Dialysis Side Effects & Monitoring
Some patients may experience dialysis side effects, including:
- Fatigue
- Muscle cramps
- Low blood pressure
- Nausea
Our care team closely monitors your response to treatment and adjusts fluid removal rates and medications as needed. Regular lab testing helps maintain safe electrolyte levels and prevent complications.
Hemodialysis vs. Peritoneal Dialysis vs. Home Hemodialysis
There are different types of dialysis, and the right option depends on your medical condition and lifestyle.
Hemodialysis
- Performed in a dialysis center
- Uses a machine to filter blood
- Scheduled multiple times weekly
Peritoneal Dialysis
- Performed at home
- Uses the abdominal lining (peritoneal membrane) to filter waste
- Typically performed daily
Home Hemodialysis
- Performed at home
- Uses a home hemodialysis machine with special dialysate fluid
- Scheduled 4-5 times per week for 3-4 hours
Some patients prefer home-based therapy, while others benefit from in-center supervision.
Your nephrologist can help determine the safest and most appropriate treatment plan.
Dialysis Diet & Lifestyle Support
Diet plays a critical role in dialysis of safety and symptom management. Patients are often advised to monitor:
- Fluid intake
- Sodium
- Potassium
- Phosphorus
Our team provides individualized nutritional counseling and ongoing lab monitoring. A proper diet helps reduce complications and supports better energy levels between treatments.
Insurance, Medicare & Dialysis Referrals
Most patients with ESKD qualify for Medicare coverage for dialysis, regardless of age. We also accept most major commercial insurance plans.
We welcome:
- New dialysis patients
- Individuals transferring from another dialysis clinic
- Referrals from nephrologists and hospital teams
Our staff assists with insurance verification and coordination before your first visit.
