Typically, a liver donor spends approximately seven days in the hospital, and will have an additional six to eight weeks of recovery time.
During the early recovery period, you will experience some pain and discomfort from your incision, which is usually well controlled with pain medications. You are monitored very closely early after surgery for all the appropriate signs of recovery and liver regeneration. Once your pain is well controlled, you are eating and drinking well and you are up and walking around without too much difficulty, you are discharged from the hospital.
After discharge, you are advised not to lift anything heavier than 20 pounds for at least six weeks. You are instructed not to drive while on sedating medications, which are used at least two to three weeks after discharge. You are encouraged to walk several times a day. If you have small children, you may need initial help in caring for them. Depending on the type of work you do, you may be able to return to work six to eight weeks after surgery. Your liver will begin to regenerate immediately after surgery and will be back to normal size in six to eight weeks. Your recovery after discharge will be closely monitored with routine clinic visits and laboratory tests.

Pain and discomfort
Nausea
Wound infection
Bleeding that may require transfusion
Blood clots
Pneumonia
Bile leakage, bile duct problems
Hernia
Scar tissue formation
In rare instances liver failure, which may require transplantation, and death may occur.
