A liver transplant is a life-saving surgical procedure performed to replace a diseased liver with a healthy one. The liver is the largest and one of the most complex organs in the body, with more than 400 functions. Damage to the liver can limit the absorption of vitamins and nutrients, prevent waste elimination and reduce the production of proteins needed to clot the blood. A person who needs a liver transplant may suffer from liver disease such as hepatitis, Wilson’s disease, blood clots, cirrhosis or autoimmune disease. One donor liver can be separated into two separate lobes and transplanted into two recipients, saving two lives.
