Liver failure occurs when large parts of the liver become damaged beyond repair and the liver is no longer able to function.
Liver failure is a life-threatening condition that demands urgent medical care. Most often, liver failure occurs gradually and over many years. However, a more rare condition known as acute liver failure occurs rapidly (in as little as 48 hours) and can be difficult to detect initially.
If detected early enough, acute liver failure caused by an overdose of acetaminophen can sometimes be treated and its effects reversed. Likewise, if a virus causes liver failure, supportive care can be given at a hospital to treat the symptoms until the virus runs its course. In these cases, the liver will sometimes recover on its own.
For liver failure that is the result of long-term deterioration, the initial treatment goal may be to save whatever part of the liver is still functioning. If this is not possible, then a liver transplant is required. Fortunately, liver transplant is a common procedure that is often successful.
