Understanding Dialysis: A Life-Saving Treatment for Kidney Disease

Kidney disease is a serious health condition that affects millions of people around the world. When the kidneys are unable to effectively filter waste and excess fluid from the blood, a medical procedure called dialysis becomes a vital lifeline. In this article, we will learn what dialysis is, its different types, reasons for its need and how it can improve the quality of life of individuals with kidney disease.

What is dialysis?

Dialysis is a medical procedure that replicates some of the functions of a healthy kidney. It is commonly used when a person’s kidneys are no longer able to perform their essential roles. The primary functions of the kidneys include filtering wastes and excess fluids from the blood, maintaining the balance of electrolytes, and controlling blood pressure.

Types of dialysis:

There are two primary types of dialysis:


Hemodialysis involves using a dialysis machine to filter the blood. During hemodialysis, the patient’s blood is pumped through a special filter (dialyzer) that removes waste and excess fluid. This filtered blood is then returned to the patient’s body. Hemodialysis is usually performed in a dialysis center, usually three times a week, and each session lasts several hours.

peritoneal dialysis:

Peritoneal dialysis uses the peritoneum, a lining inside the abdominal cavity, as a natural filter. A special dialysis solution is inserted into the abdominal cavity through a catheter. This solution absorbs the waste and excess fluid, and after a few hours it is flushed out, taking with it the impurities. Peritoneal dialysis can be done at home, giving patients greater flexibility and independence.

Reasons for dialysis:

Dialysis is primarily recommended for individuals with end-stage kidney disease, where the kidneys have lost almost all of their function. Common reasons for needing dialysis include:

Chronic Kidney Disease (CKD): In the advanced stages of CKD, the kidneys become unable to perform their filtration functions effectively.

Acute kidney injury (AKI): Severe and sudden kidney damage may require temporary dialysis until the kidneys heal.

Some chronic diseases: Conditions such as diabetes and high blood pressure can cause kidney damage, which may require dialysis.

Hereditary Kidney Disease: Some people are born with genetic kidney problems that may require dialysis.

Benefits of Dialysis:

Dialysis plays an important role in maintaining the health and quality of life of people suffering from kidney disease. Its benefits include:

waste removal: Dialysis helps remove harmful waste products from the body that accumulate when the kidneys do not function properly.

fluid balance: It helps regulate fluid levels in the body, which is essential for maintaining blood pressure and overall health.

Electrolyte Balance: Dialysis helps maintain the balance of essential electrolytes such as sodium and potassium.

better health: By providing these vital functions, dialysis can significantly improve a patient’s overall well-being and quality of life.
