TCM Analysis of the Causes of Blood in the Stool

Hematochezia is also known as "bloody stool", "bleeding" and "hemedema", and is characterized by bloody stool or fresh stool after defecation. It is more common in upper gastrointestinal ulcer bleeding, gastrointestinal polyps, small intestinal bleeding, tumors, bleeding from perianal diseases, as well as some blood diseases, acute infectious drugs, parasites, etc. This refers to blood in the stool caused by hemorrhoid rupture, anal fissure, anal sinusitis, and rectal colon mucosal damage. The stool is soft and formed or hard, with blood attached to the surface of the stool. Sometimes the blood comes before the stool, and sometimes the stool comes before the blood. The blood is mostly bright red, and sometimes dark red and turbid. When the amount of blood is large, it will not stop dripping, and the pain in the anus will worsen after defecation.
