What is dialysis?
user
The process of dialysis is used to treat patients who have kidney failure.   The kidneys are two organs that clean the blood of waste products.   They also produce hormones that control the levels of substances in the blood.

Does it make the patients weak and sick?
user
It might, especially if the kidneys are very sick.   Sometimes when the kidneys don’t work as well, fluid builds up in the body.   The dialysis machine pulls the fluid out of the patient’s body.   But this treatment is very helpful.  Without dialysis, some patients might die.
assistant
That is very sad.
