What is Dialysis? Types, Process & Side Effects
Dialysis is a life-saving treatment for people whose kidneys are no longer able to function properly. When the kidneys fail to filter waste, excess fluids, and toxins from the blood, dialysis steps in to perform this critical function.
If you’ve been advised by a Kidney Doctor Dubai or a Kidney Specialist Doctor In Dubai, understanding how dialysis works can help you feel more prepared and confident about the treatment process.
What is Dialysis?
Dialysis is a medical procedure that removes waste products, excess fluids, and toxins from the blood when the kidneys are damaged or fail completely. It is commonly recommended for patients with advanced kidney disease or kidney failure.
A qualified Nephrologist In Dubai or the Best Nephrologist In Dubai will determine when dialysis is necessary based on your kidney function and overall health condition.
Why is Dialysis Needed?
Dialysis is required when kidney function drops to a critical level (usually below 10–15% of normal function). Common reasons include:
Chronic Kidney Disease (CKD)
Acute Kidney Failure
Diabetes-related kidney damage
High blood pressure complications
Genetic kidney disorders
Consulting a Kidney Specialist Doctor In Dubai helps in early diagnosis and timely treatment planning.

Typically done in a hospital or dialysis center
Performed 3–4 times a week, each session lasting 3–5 hours
This is the most common type and is often recommended by a Kidney Doctor Dubai.
๐ 2. Peritoneal Dialysis

Uses the lining of the abdomen (peritoneum) as a filter
Can be done at home
Requires daily exchanges of dialysis fluid
Many patients prefer this option for flexibility, under the guidance of a Nephrologist In Dubai.
