Dialysis is a medical procedure that helps filter the blood in a person's body when their kidneys are unable to do so. The term "Dialyses" refers to multiple instances of the procedure, but there are a few antonyms to this word. One such antonym is "kidney function," which means that a person's kidneys are working properly, and there is no need for dialysis. Another antonym is "prevention," meaning that measures have been taken to avoid or delay the need for dialysis. Lastly, "recovery" could also serve as an antonym for Dialyses, which would mean that a person's kidney function has improved, and dialysis is no longer needed.
