Organ transplant is surgery that replaces a diseased organ (such as a kidney, liver, heart, lungs, pancreas, or intestine) with a healthy organ from a donor. Donated organs come from both living donors and people who decided to donate organs upon their death.

After an organ transplant, a person will need to make certain lifestyle changes (such as consistently getting good nutrition, regular sleep, and exercise) along with taking numerous daily medicines that prevent the body from rejecting the new organ.
