"How does living donation affect the donor?
People can live normal lives with only one kidney. As long as the donor is evaluated thoroughly and cleared for donation, he or she can lead a normal life after the surgery.
When the kidney is removed, the single normal kidney will increase in size to compensate for the loss of the donated kidney.
The American Academy of Pediatrics, American Academy of Family Physicians and the Medical Society of Sports Medicine have suggested that people with one kidney avoid sports that involve higher risks of heavy contact or collision. This includes, but is not limited to, boxing, field hockey, football, ice hockey, Lacrosse, martial arts, rodeo, soccer and wrestling. This may also include extreme activities such as skydiving. Anyone with a single kidney who decides to participate in these sports should be extra careful and wear protective padding. He or she should understand that the consequences of losing a single kidney are very serious."
