Kidney disease can be a devastating diagnosis. The kidneys are essential for removing waste and excess fluid from the body.
When they stop functioning correctly, waste and excess fluids can build up, leading to complications like high blood pressure, anemia, nerve damage, and even death.
Hemodialysis is a treatment that helps filter the blood and remove waste and excess fluid in patients with kidney disease. In this article, we’ll explore what hemodialysis is, how it works, and who may benefit from this treatment.
What is Hemodialysis?
Hemodialysis is a medical treatment used to help clean the blood in patients with kidney disease. During hemodialysis, blood is filtered through a machine that helps remove waste, excess fluid, and toxins from the body.
There are two types of hemodialysis, hemodialysis using an arteriovenous fistula (AVF) or graft (AVG), and hemodialysis using a catheter. An AVF is created surgically by connecting an artery to a vein in the arm.
An AVG is a synthetic tubing graft that connects an artery to a vein. A catheter is a tube that is inserted into a large vein, usually in the neck or groin area.
How Does Hemodialysis Work?
Hemodialysis uses a machine that is connected to the AVF, AVG, or catheter. The machine has a filter called a dialyzer, which helps clean the blood. The patient’s blood is pumped through the dialyzer, where it is cleaned using a fluid called dialysate.
The cleaned blood is then returned to the patient’s body.
The process of hemodialysis usually takes three to four hours and is typically performed two to three times per week. However, the frequency and duration of hemodialysis can vary based on the patient’s individual needs.

Who Needs Hemodialysis?
Hemodialysis is a treatment used for patients with kidney disease who have reached end-stage renal disease (ESRD). ESRD is a condition where the kidneys have lost almost all of their function.
Hemodialysis can help alleviate the symptoms of ESRD and improve the quality of life for patients.
In addition to ESRD, hemodialysis may also be used for patients with acute kidney injury (AKI). AKI occurs when the kidneys suddenly stop functioning or when they are weakened due to another medical condition.
Hemodialysis can help remove excess fluids and waste from the body while the patient’s kidneys recover.
The Benefits of Hemodialysis
There are several benefits to hemodialysis for patients with kidney disease. These benefits include:.
- Improved Quality of Life: Hemodialysis can help alleviate the symptoms of kidney disease, such as nausea, vomiting, and fatigue, which can improve a patient’s overall quality of life.
- Reduced Risk of Complications: Hemodialysis helps remove excess fluids and waste from the body, which can help reduce the risk of complications like high blood pressure, nerve damage, and anemia.
- Extended Life Expectancy: Hemodialysis can help extend the life expectancy of patients with ESRD.
Risks of Hemodialysis
While hemodialysis is a safe and effective treatment for kidney disease, there are some risks associated with the treatment. These risks include:.
- Infection: Hemodialysis requires access to the bloodstream, which can increase the risk of infection.
- Low Blood Pressure: Hemodialysis can cause a drop in blood pressure, which can lead to dizziness and other symptoms.
- Bleeding: There is a risk of bleeding during hemodialysis if the patient has a clotting disorder or is taking blood thinners.
Despite these risks, the benefits of hemodialysis far outweigh the potential complications for patients with kidney disease.
Conclusion
Hemodialysis is a vital treatment for patients with kidney disease who have reached end-stage renal disease or who are experiencing acute kidney injury.
While the treatment comes with some risks, it provides significant benefits and can improve the quality of life for patients. If you or someone you know has kidney disease, talk to your healthcare provider about hemodialysis as a potential treatment option.
