Blood in the stools
Since liver cirrhosis patients have a slow healing process, those who suffer from gastrointestinal problems such as duodenal or stomach ulcers would have a worse prognosis. They would have sustained gastrointestinal bleeding, which in most cases appear in the stools.
Blood in the stools can be either macroscopic, or clearly visible, or microscopic, which is only traceable under a microscope. Macroscopic blood often changes the color of the stools to a darker black, and it has a strong smell that results from the decay of blood when it comes into contact with the gut microbiota.
