Liver failure refers to a functional impairment of the liver, which could be acute or chronic damage. For instance, it could be the end stage of chronic liver disease, or an acute condition such as hepatitis, or another acute liver lesion. Other common lesions may also cause a sudden abnormality in liver function, resulting in severe liver dysfunction. At this point, liver cirrhosis is a common cause of liver failure. For example, in the middle and late stages of liver cirrhosis, liver function is completely decompensated, meaning the liver can no longer maintain its basic normal functions, leading to liver failure. Therefore, liver failure is one of the major consequences of liver cirrhosis, but the two are distinct. Liver failure can also be caused by other reasons not related to cirrhosis. For example, acute ischemia in the liver, such as in shock patients, can lead to liver ischemia and subsequently liver failure. Liver cirrhosis is just one of the common causes thereof.
