Learn if you can live without a liver

The liver is one of the largest and most important organs in your body.

Found in your upper-right abdomen, just below your diaphragm, the liver performs more than 500 different functions including:

  • Processing nutrients
  • Breaking down fats
  • Storing vitamins
  • Metabolizing proteins
  • Breaking down old blood cells

So, Can You Live Without Your Liver?

No. Your liver is so vital that you cannot live without it.

But it is possible to live with only part of your liver.

Liver Regeneration

The liver is the only organ in your body that can regenerate itself, or grow back, after damage or surgical removal.

While it seems hard to believe, your liver really can grow back to its full size and function in a few months.

Living-Donor Liver Transplants

Because your liver grows back, you can actually donate a piece of your liver to someone else.

There’s a growing waiting list for liver transplants, but a shortage of deceased-donor organs. A living-donor liver transplant is a lifesaving option for someone in need of a new liver.

During a living-donor liver transplant, doctors remove a piece of your healthy liver. They then use it to replace the damaged liver of a recipient.

After surgery, your liver will regenerate back to its full size. The other person’s new liver will grow as well, leaving both people with healthy, functioning livers.

Living-donor liver transplants are possible for both adults and children.

How Much of My Liver Will Be Removed?

It depends on the size of the person you’re donating to.

It’s possible to remove between 25 to 65 percent of your liver and it will still grow back in a few months.

How to Become a Living Liver Donor

With more than 15,000 people waiting for a liver transplant, living-donor liver transplants save lives.

So although you can’t live without your liver, you can share part of it with someone else in need.

To be a living liver donor, you must:

  • Be between the ages of 18 and 55
  • Be in good general health
  • Have no history of:
