What Does the Liver Do?
The liver is a large, reddish-brown organ located on the right side of your upper belly, just under the ribs. It’s like your body’s personal filter and chemical factory.
Here’s what it does:
Cleans your blood by removing toxins
Helps digest food by producing bile
Stores energy (in the form of sugar called glycogen)
Helps clot blood to stop bleeding
Processes medicines and alcohol
You can’t live without your liver—but the amazing part is, the liver can regrow after part of it is removed!
Why Would Someone Need Liver Surgery?
There are several reasons a person might need liver surgery, such as:
Liver cancer – either starting in the liver or spreading from another organ
Liver cysts or benign tumors – non-cancerous growths that may cause problems
Liver injury or trauma – due to accidents or internal bleeding
Liver donation – in living-donor liver transplant
Hydatid cyst – caused by a parasite, common in some countries
Bile duct issues – sometimes part of the liver must be removed
Types of Liver Surgeries
Liver Resection (Hepatectomy):
Removal of part of the liver. This could be a small portion or even up to half, depending on the problem.
Liver Transplant:
Removing a damaged liver and replacing it with a healthy one (from a donor). This is done for people with liver failure.
Laparoscopic (Minimally Invasive) Liver Surgery:
Performed through small cuts using a camera. Less pain and quicker recovery.
What to Expect Before Surgery
Blood tests, CT or MRI scans
Possibly a liver biopsy
A discussion with your surgeon about the risks, benefits, and recovery
Stop certain medicines, fast before surgery
You might also be evaluated to see if your liver can regenerate well after surgery.
Recovery After Liver Surgery
Recovery depends on how much liver was removed and your general health. Here’s what’s common:
Hospital stay: usually 3–7 days (longer for transplant)
Pain is managed with medications
Gradual return to normal activities
Full recovery: usually a few weeks to months
The liver starts growing back within weeks—an amazing fact!
Are There Risks?
Yes, like any surgery, there are possible risks:
Bleeding (liver has a lot of blood vessels)
Infection
Bile leakage
Temporary liver dysfunction
But with experienced surgical teams and modern techniques, many liver surgeries are safe and successful.
Living With One Part of Your Liver
Most people live completely normal lives with part of their liver removed. After recovery:
Eat a healthy, low-fat diet
Avoid alcohol
Stay active
Follow-up with your doctor regularly
Final Words
Liver surgery might sound overwhelming, but it’s often a life-saving or life-improving procedure. Whether its to remove a tumor, treat trauma, or donate to someone in need, liver surgery is backed by decades of medical progress and expertise.
If you or a loved one is facing liver surgery, know this: the liver is strong, and so are you.
