Dialysis removes waste and fluids from your body that your kidneys are not able to remove. Dialysis also aims to keep your body in balance by correcting the levels of various toxic substances in your blood.hichever treatment is chosen, the aims of dialysis are very similar: dialysis is designed to replace several functions of the kidney. The therapy must: remove waste products, remove excess fluid and balance the amount of chemicals (electrolytes) and other substances in your body.
Although dialysis helps patients whose kidneys have failed, it is not as efficient as a normal kidney. Consequently, patients on dialysis need to be careful about what and how much they drink and eat. They will also need medications. A significant number of patients on dialysis can work and lead normal lives.eople whose kidneys either do not work properly or not at all experience a buildup of waste in their blood. Without dialysis the amount of waste products in the blood would increase and eventually reach levels that would cause coma and death. Dialysis is also used to rapidly remove toxins or drugs from the blood.
