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.
assistant
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.
user
But the dialysis machine can help.   Unfortunately, the number of patients who need this treatment is increasing.   However, a lot of work is being done to find other treatments for kidney disease.   This is a long-term effort.   It will take many years to develop.

Yes, it is.  But it is a sad thing that sometimes happens.   It is the nature of the universe to cause harm.  When this happens it’s best to find out how to help.  If there was a new kind of treatment for the kidney failure, would you like to know about it?
