She has been given a second chance at life.
Because of the illness, Hyland’s kidneys developed unsightly growths, which made it impossible for the organs to execute their basic function, which is to remove waste from the circulation. This caused Hyland a lot of discomfort. As a direct consequence of this, Hyland’s kidneys were unable to perform their normal functions.
In the end, both of her kidneys stopped functioning properly, and she had a kidney transplant in order to keep surviving. She was not a good candidate for the dialysis treatment, unfortunately. Because her father’s organ was a match with the one that was necessary to save her life, he generously gave it to her so that she might continue living. Because of this, she was able to survive.
