 Hi, I am Dr. Ravichan Siddhachari. I am a consultant hepatobiliary and liver transplant surgeon for Manipal Hospital group Bangalore There are two kinds of donation one is the cadaver and the other is the living person donating part of his liver When it comes to cadaver donation somebody with a brain is dead There is no age barrier in this case any age is okay for liver donation a person as old as 80 and above can also donate provided his liver quality is good So at the same time somebody like an infant also can donate liver which can be used for another small child When it comes to living related liver transplants, there is age limit as per the law any person younger than 18 cannot donate liver and There is no upper limit the lower limit is 18 years upper limit We go up to 40 to 50 years because the liver quality declines with the age So normally we accept a person with between 18 and 40 years of age for living donation
