Can you live with one lung if you chose to donate one?
People can survive even if an entire lung is removed.
Healthy, and non-smoking adults, can donate part of one of their lungs and live a normal life after the surgery. The lung that remains will inflate to take up some extra space. Usually, it doesn't affect everyday tasks or life expectancy. The donor will be able to live a normal life in all aspects with less exercise tolerance for competitive sports. However, on some occasions risks and complications can occur for the donor.
