Cirrhosis is a condition in which the liver slowly deteriorates and malfunctions due to chronic injury. Scar tissue replaces healthy liver tissue, partially blocking the flow of blood through the liver. Scarring also impairs the liver’s ability to control infections, remove bacteria and toxins from the blood, process nutrients, hormones, and drugs, make proteins that regulate blood clotting, and produce bile to help absorb fats— including cholesterol—and fat-soluble vitamins.
A healthy liver is able to regenerate most of its own cells when they become damaged. With end-stage cirrhosis, the liver can no longer effectively replace damaged cells. A healthy liver is necessary for survival.
