Cirrhosis - Topic Overview
Cirrhosis (say "suh-ROH-sus")
is a very serious condition in which scarring damages the

- Filters poisons from the blood.
- Breaks down

When a person has cirrhosis, scar tissue (fibrosis ) replaces healthy tissue. This scar tissue prevents the
liver from working as it should. For example, the liver may stop producing

in the vein that carries blood from the intestines through the liver (portal hypertension). This can lead to severe bleeding
in the digestive tract and other serious problems.
