Liver is the largest and one of the most important organs in the human body. It is responsible for the optimal performance of several metabolic functions such as digestion of food, storage of vitamins, minerals, and sugars, removing toxins, manufacturing bile, and helping the body fight infection. Liver failure due to a disease or lifestyle choices (such as alcoholism) could be potentially life threatening. In such a condition, a doctor is likely to recommend screening for liver transplant. If the criteria for transplant are cleared and a matching donor liver found, a major surgery is undertaken to perform the transplant. The donor may be dead or living. In case of living donors, the portion of the liver donated regrows to its full size. After a transplant, the patient may be required to be on strong medication and closely monitored for a long time.
