Late-stage symptoms. In the later stages of cirrhosis, you may vomit blood or have tarry, black stools. This is because blood can’t flow through the liver properly, which causes an increase in blood pressure in the vein that carries blood from the gut to the liver (portal vein).

The increase in blood pressure forces blood through smaller, fragile vessels that line your stomach and gullet (varices). These can burst under high blood pressure, leading to internal bleeding, which is visible in vomit and/or stools.

Over time, the toxins that would normally be removed from the body by a healthy liver can cause multiple organ failure, followed by death.
