Bleeding stool may be caused by fire. In addition to fire, other diseases may also cause bleeding stool, so the cause should be clarified and treated accordingly. Fire means that the internal fire in the body is strong, which can lead to dry and hard stools, and when the mucous membrane around the anus is cut during discharge, the phenomenon of bleeding stools will occur. Anorectal diseases such as hemorrhoids and anal fissures may also cause bleeding stools. Usually, anal fissure bleeding is mostly accompanied by pain, bright red blood, dry, hard stools, and periodic pain; internal hemorrhoid bleeding is also bright red, but there is no obvious pain, and the bleeding stops after the stool. In addition, intestinal polyps, rectal cancer and other diseases can also show symptoms of bleeding stools, so fire can cause bleeding stools, but the cause of bleeding stools is not limited to fire. If you have bleeding stools, besides identifying the cause, you should avoid spicy and irritating foods in your diet, eat more vegetables and fruits with coarse fiber and high water content, drink more water, and laxative.
