Donated livers can originate from bodies or living contributors. When it comes to living benefactors, the donor contributes part of his/her liver to another individual, according to the American College of Gastroenterology. The liver can regrow itself, so both people need to end up with healthy, functional livers. There might be no signs and symptoms of a bigger liver, though if they are they are the same as the symptoms for liver condition. Typically, the liver can not be really felt unless you take a deep breath, however if it is bigger, your doctor might have the ability to feel it, according to the NIH.
